Components of Nervous Co Ordination

NERVOUS CO-ORDINATION:


This type of co-ordination involves specialized cells or neurons linked together directly or via the central nervous system, to form a network that connects the cell organs which receive stimuli (receptors) and those which carry out actions or responses (effectors). The neuron has the ability to generate and conduct impulses which travel across the synapse and pass from the receptors to the effectors, brings about nervous co-ordination. The elements of the nervous system which helps co-ordination are:
  • Receptors
  • Neurons
  • Effectors
    The neuron fibers and cell bodies can be excited by slight electric shocks, mechanical, chemical, light and temperature stimuli. Receptors detect changes in the external and internal environment of the animal. The receptor may be a cell, or neuron ending or a receptor organ. Receptors are classified as follows:

    Chemoreceptors:

    These are for smell, taste and for blood Carbon dioxide, oxygen, glucose, amino acids and fatty acids.

    Mechanoreceptors:

    These detect stimuli of touch, pressure, hearing and equilibrium.
    (E.g. free nerve endings + expanded tip endings + Stray endings)

    Photoreceptors: 

    These (electromagnetic receptors) respond to stimuli of light for example in eyes, rods and cones.

    Thermoreceptors:

    These are free nerve endings. These show response to cold and warmth.

    Nocireceptors:

    (Undifferentiated endings) which produces the sensation of pain.

    Structure of five different types of sensory receptors in brain
    Each type of principal type of sensation that we can experience_ pain, touches, sight, sound and so forth are called Modalities of sensation. Yet despite the fact that we experience these different modalities of sensation; nerve fibers transmit only impulses. How is it that different nerve fibers transmit different modalities of sensation? The answer to this question is:
    Each nerve tract terminates at a specific point in the CNS; and the type of sensation is determined by the point in the nervous system to which the fiber leads. So touch stimulus is carried by the nerve impulse in the ‘touch’ area of the brain. Similarly fibers from the eyes (retina) terminate in the visual cortex of the brain.


    There are numerous receptors which respond to mechanical conditions of internal organs. Examples are the receptors of the stomach wall which may be concerned with arousal of ‘hunger’; stretch receptors in the carotid and aortic arteries of tetrapods have important roles in regulation of blood pressure; endings with similar properties are found in branchial vessels of fishes.

    Neurons:

    "The structural and functional unit of the nervous system in all animals including man is the neuron”. This is a highly specialized cell which contains the typical organelles found in most eukaryotic cells. This cell is particularly adapted for communication because of its wire like projection; the dendrites which are often further branched and carry impulses towards the central cell body. The cell body is the thicker region of the neuron containing the nucleus and most of the cytoplasm. The axon is the projection, generally very long, that carries impulses away from the cell body. Usually a neuron has a single axon. A fatty substance covering the axon is the myelin sheath along with short regions of exposed axons is called Nodes of Ranvier. Many axons and even dendrites combine to form a single nerve. 

    The chief structural and functional units of the nervous system are neurons, but there are other cells, in higher animals, and in humans called neuroglia, which make up as much as half of the nervous system. Neuroglia plays a vital role in the nutrition of neurons and their protection from the myelin sheath. There are three functional types of neurons:

    • Sensory
    • Associative (intermediate/relay)
    • Motor

    The neuron has protoplasmic processes arising from its cell body containing a nucleus and various organelle embedded in the cytoplasm. There are two main types of cytoplasmic processes or fibers. One which carries impulse towards cell body is called Dendron, if it is a single fiber, but if smaller fibers _they are called dendrites (singular: dendrite). The processes conducting impulses away from the cell body are termed axons: These may be more than a meter long in some neurons. Nissls granules which are groups of ribosomes associated with rough E.R and Golgi apparatus are present in the cell body. Microtubules, neurofibrils, rough endoplasmic recticulum and mitochondria are present throughout the axoplasm of neuron.
    The cell body or soma is the main nutritional part of the cell and is concerned with the biosynthesis of the materials necessary for the growth and maintenance of the neuron. If the cell body of the neuron remains intact, it can regenerate axonal and dendrite fibers; but neurons once mature, do not divide any further.
    Effectors:
    These are the structures which respond when they are stimulated by impulses coming via motor neuron. The principal effectors is glands, which respond by secreting; and muscles which respond by contracting. Flow of information through the nervous system is explained with the help of a reflex arc.
    Effectors in Human Body
    Reflex Arc:

    Flow of impulse through the nervous system involving receptors, neurons and effectors will be quite clear if we study an example of a reflex arc. Reflex arc is the pathway of passage of an impulse during a reflex action. Reflex action is a form of involuntary action. The direction of stimulus is from receptors to the sensory neuron to associative (Association / relay) neuron and then through the motor neuron to the effectors. 

    Autonomic Reflex:

    Any of a large number of normal reflexes governing and regulating the functions of the viscera.
    Autonomic reflexes control such activities of the body as blood pressure, heart rate, peristalsis, sweating, and urination.

    Autonomic Reflex

    Somatic Reflex:

    An involuntary control system characterized by a control loop which includes skeletal muscles.

    Kissing an octopus and other diversions

    In Washington, a Pacific Giant Octopus is released into the wild with a kiss!  I dont know that Id kiss a cephalopod, but the picture of science center directer Patrick Mus doing it is pretty darling.

    The German branch of PETA released a statement demanding that Paul the (psychic) octopus be released into the wild, claiming that octopuses are "capable of complex thought processes, they have short- and long-term memories, use tools, learn by observation, show different personalities and are particularly sensitive to pain."  Id argue that their first point is highly dependent on the definitions of "complex" and "thought processes", their second point says little about the intellectual capacity of an animal, their third point is contentious even among those who care, being supported by a very few examples, their fourth point is based on one study that (as far as I know) has not been replicated, their fifth point is only supported by anecdotal evidence (and "personality" is a very loosely defined term,) and their last point (again, as far as I know,) has never been specifically investigated.  Nonetheless, it makes good news.

    In the town of Whyalla (where our heroes from the last link post were arrested for stealing cuttlefish,) cuttlefish are an important tourist trap, as well as possibly being a special, isolated genetic pool.  If I were in Australia, Id go see them.

    In the most exciting recent news story (in my opinion, at least,) a deep sea squids penis is seen in action.  Really.  No, Im not joking.  Just click it.

    Partially in response to the whole Pepsi-blog incident at Science Blogs (which seems to have mostly resolved pretty quickly,) Adam Bly, CEO of SEED Media Group has started a new blog, Science is Culture.  In response to the fiasco, Ive updated my blogroll to link to the new locations of those who left Science Blogs.

    Ive also updated my format and added some new folks to the blogroll.  Im working on a few posts at the moment (including a cephalopod reading list with reviews,) so stay tuned!

    THESEUS Greek Mythology Legends

    Aegeus, king of Athens, being twice married, and having no children, was so desirous of an heir to his throne that he made a pilgrimage to Delphi in order to consult the oracle. But the response being ambiguous, he repaired to Troezen to consult his wise friend Pittheus, who reigned over that city, by whose advice he contracted a secret marriage with his friends daughter Aethra.

    After passing some time with his bride, Aegeus prepared to take his departure for his own dominions; but before doing so he led Aethra to the sea-shore, where, after depositing his sword and sandals under a huge rock, he thus addressed her: "Should the gods bless our union with a son, do not reveal to him the name and rank of his father until he is old enough to possess the strength requisite for moving this stone. Then send him to my palace at Athens bearing these tokens of his identity."

    A son was born to Aethra, whom she called Theseus, and who was carefully trained and educated by his grandfather Pittheus. When he had developed into a strong and manly youth his mother conducted him to the spot where the rock had been placed by Aegeus, and at her command he rolled away the stone, and took possession of the sword and sandals which had lain there for sixteen years, and which she now desired him to convey to his father Aegeus, king of Athens.

    His mother and grandfather were anxious that the youth should travel by the safe sea route, the road between Troezen and Athens being at this time infested with robbers of great ferocity and enormous strength. But feeling within himself the spirit of a hero, Theseus resolved to emulate the deeds of Heracles, with whose fame all Greece resounded, and therefore chose the more dangerous journey by land, as calculated to afford him an opportunity of distinguishing himself by feats of valour.

    His first adventure occurred at Epidaurus, where he met Periphetes, a son of Hephæstus, who was armed with an iron club, with which he killed all travellers. Having received from his grandfather a full description of this savage, Theseus at once recognized him, and rushing upon him with his sword, succeeded after a desperate encounter in killing him. He appropriated the club as a trophy of his victory, and proceeded on his journey without hinderance until he arrived at the Isthmus of Corinth.

    Here the people warned him to beware of Sinnis the robber, who forced all travellers to bend with him one of the branches of a tall pine-tree. Having dragged it to the ground, the cruel Sinnis suddenly released his hold, whereupon the bough rebounding high up into the air, the unfortunate victim was dashed to the ground and killed. When Theseus beheld Sinnis advancing towards him he steadily awaited his approach; then seizing his powerful club, he killed the inhuman wretch with one blow.

    Passing through the woody district of Crommyon Theseus next slew a wild and dangerous sow which had long ravaged the country.

    He then continued his journey and approached the borders of Megara, where, on a narrow path overhanging the sea, dwelt the wicked Scyron, another terror to travellers. It was his custom to compel all strangers who passed his abode to wash his feet, during which operation he kicked them over the rock into the sea. Theseus boldly attacked the giant, overcame him, and then flung his body over the cliff where so many of his victims had perished.

    Theseus now journeyed on to Eleusis, where he found another adversary in the person of King Cercyon, who forced all comers to wrestle with him, and killed those whom he vanquished; but Theseus overcame the mighty wrestler and slew him.

    Near Eleusis, on the banks of the river Cephissus, Theseus met with a new adventure. Here lived the giant Damastes, called Procrustes or the Stretcher, who had two iron beds, one being long and the other short, into which he forced all strangers; In the short one he placed the tall men, whose limbs he cut to the size of the bed, whilst to the short ones he assigned the large bed, stretching them out to fit it; and thus he left his victims to expire in the most cruel torments. Theseus freed the country from this inhuman monster by serving him as he had done his unfortunate victims.

    The hero now continued his journey, and at length reached Athens without meeting with any further adventures. When he arrived at his destination he found his father a helpless tool in the hands of the sorceress Medea, whom he had married after her departure from Corinth. Knowing, by means of her supernatural powers, that Theseus was the kings son, and fearing that her influence might be weakened by his presence, she poisoned the mind of the old king against the stranger, whom she represented as being a spy. It was accordingly arranged that Theseus should be invited to a banquet, and a strong poison mixed with his wine.

    Now Theseus had resolved to reveal himself at this feast to the father whom he yearned to embrace. Before tasting the wine he put his plan into execution, and drew out his sword so that the eyes of the king might rest upon it. When Aegeus beheld once more the well-known weapon which he had so often wielded, he knew that it was his son who stood before him. He warmly embraced him, presented him as his heir to his courtiers and subjects, and then, no longer able to endure the sight of Medea, he banished her for ever from his dominions.

    When Theseus was acknowledged as the rightful heir to the throne he was opposed by the fifty sons of Pallas, the kings brother, who had confidently expected that on the demise of the old king the government of the country would devolve upon them. They therefore resolved to put Theseus to death; but their plans becoming known to him, he surprised them as they lay in ambush awaiting his approach, and destroyed them all.

    Fearing, however, lest the Athenians might entertain a prejudice against him on account of his extermination of their fellow-citizens, the Pallantids, Theseus resolved to perform some signal service for the state, which should gain for him the hearts of the people. He accordingly decided to rid the country of the famous bull of Marathon, which had become a terror to the cultivators of the land. He captured the animal and brought him in chains to Athens, where, after publicly exhibiting him to the astonished multitude, he solemnly sacrificed him to Apollo.

    The next enterprise undertaken by Theseus far surpassed all his other feats of heroic daring, and secured to him the universal admiration and gratitude of his fellow-citizens. This was the slaying of the Minotaur, which put an end for ever to the shameful tribute of seven youths and seven maidens which was exacted from the Athenians every nine years.

    The origin of this barbarous tribute was as follows: Androgeos, the youthful son of Minos, king of Crete, having been treacherously murdered by the Athenians, his father, anxious to avenge the death of his son, declared war against their king Aegeus, and conquered Athens and the villages in its vicinity. The conqueror henceforth compelled the Athenians to send to him every nine years a tribute of seven youths and seven maidens of the noblest families of the land, who became the prey of the Minotaur, a monster, half-man, half-bull, whose lair was in the wonderful labyrinth, constructed by Dædalus for the Cretan king.

    When Theseus informed his father of his heroic determination, he was overwhelmed with grief, and endeavoured, by every means in his power, to shake his sons resolution, but, confident of success, Theseus assured his father that he would slay the Minotaur and return home victorious.

    It was customary for the vessel bearing its unhappy freight of human victims to use on this voyage black sails only; but Theseus promised his father that, should he return in safety, he would hoist white ones in their place.

    Before leaving Athens Theseus, by the advice of an oracle, chose Aphrodite as his guardian and protectress, and accordingly offered up a sacrifice to her. When he arrived in the presence of king Minos, the goddess of Love inspired Ariadne, the beautiful daughter of the king, with an ardent attachment for the noble young hero. During a secret interview, in which a mutual confession of affection took place, Ariadne furnished him with a sharp sword and a clue of thread, the end of which she desired him to fasten at the entrance to the labyrinth and to continue to unwind it till he reached the lair of the Minotaur. Full of hope as to the successful issue of his undertaking, Theseus took leave of the kind maiden, after expressing his gratitude for her timely aid.

    At the head of his companions he was now conducted by Minos to the entrance of the labyrinth. Strictly adhering to the injunctions of the fair Ariadne he succeeded in finding the Minotaur, whom, after a fierce and violent struggle, he defeated and killed; then carefully feeling his way, by means of the clue of thread, he led his companions safely out of the labyrinth. They then fled to their ship, taking with them the lovely maiden to whose affection for their deliverer they owed their safety.

    Arrived at the island of Naxos, Theseus had a dream, in which Dionysus, the wine-god, appeared to him, and informed him that the Fates had decreed that Ariadne should be his bride, at the same time menacing the hero with all kinds of misfortunes should he refuse to resign her. Now Theseus, having been taught from his youth to reverence the gods, feared to disobey the wishes of Dionysus. He accordingly took a sad farewell of the beautiful maiden who so tenderly loved him, and left her on the lonely island, where she was found and wooed by the wine-god.

    Theseus and his companions felt keenly the loss of their benefactress, and in their grief at parting with her, forgot that the ship still bore the black sails with which she had left the Attic coast. As she neared the port of Athens, Aegeus, who was anxiously awaiting the return of his son on the beach, caught sight of the vessel with its black sails, and concluding that his gallant son had perished, threw himself in despair into the sea.

    With the unanimous approval of the Athenians, Theseus now ascended the vacant throne, and soon proved himself to be not only a valiant hero but also a wise prince and prudent legislator. Athens was at this time but a small city surrounded by a number of villages, each of which possessed its own separate form of government; but by means of kind and conciliatory measures Theseus induced the heads of these different communities to resign their sovereignty, and to intrust the administration of public affairs to a court which should sit constantly at Athens, and exercise jurisdiction over all the inhabitants of Attica. The result of these judicious measures was, that the Athenians became a united and powerful people, and that numbers of strangers and foreigners flocked to Athens, which became a flourishing maritime port and a commercial centre of great importance.

    Theseus renewed the Isthmian Games, and also instituted numerous festivals, the principal of which was the Panathenæa, held in honour of Athene-Polias.

    It is related that Theseus upon one occasion arrived during a voyage at the Amazonian coast. Anxious to ascertain the object of his visit, the Amazons sent Hippolyte, one of their number, with presents to the stranger; but no sooner did the fair herald set foot on board his vessel than Theseus set sail and carried her off to Athens, where he made her his queen. Enraged at this indignity the Amazons determined to be revenged. Some time afterwards, when the whole affair would appear to have been forgotten, they seized the opportunity when the city of Athens was in a defenceless condition and landed an army in Attica. So sudden was their attack that they had penetrated into the very heart of the city before the Athenians could organize their forces; but Theseus expeditiously collected his troops and commenced such a furious onslaught upon the invaders that, after a desperate encounter, they were driven from the city. Peace was then concluded, whereupon the Amazons evacuated the country. During this engagement Hippolyte, forgetful of her origin, fought valiantly by the side of her husband against her own kinsfolk, and perished on the field of battle.

    Hippolyte

    It was soon after this sad event that Theseus joined the world-renowned Calydonian Boar-hunt, in which he took a leading part. He also formed one of the brave band who shared in the perils of the Argonautic expedition.

    The remarkable friendship which existed between Theseus and Pirithöus originated under such peculiar circumstances that it is worthy of mention.

    Hearing upon one occasion that his herds, pasturing in the plains of Marathon, had been carried off by Pirithöus, Theseus collected together an armed force and sallied forth to punish the plunderer. But, when the two heroes met face to face, both were seized with an impulse of sympathetic admiration for each other. Pirithöus, holding out his hand in token of peace, exclaimed, "What satisfaction shall I render thee, oh Theseus? Be thou thyself the judge." Theseus seized the proffered hand and replied, "I ask nought save thy [266]friendship;" whereupon the heroes embraced each other and swore eternal fidelity.

    When, soon afterwards, Pirithöus became united to Hippodamia, a Thessalian princess, he invited Theseus to the wedding-feast, which was also attended, among other guests, by a large number of Centaurs, who were friends of Pirithöus. Towards the end of the banquet Eurytion, a young Centaur, heated and flushed with wine, seized the lovely bride and sought by force to carry her off. The other Centaurs, following his example, each endeavoured to capture a maiden. Pirithöus and his followers, aided by Theseus, who rendered most valuable assistance, attacked the Centaurs, and after a violent hand-to-hand struggle in which many perished, forced them to relinquish their prey.

    After the death of Hippolyte Theseus sought the hand of Phædra, the sister of his former bride Ariadne, to whom he became united. For some years they lived happily together, and their union was blessed by the birth of two sons. During this time Hippolytus, the son of the Amazonian queen, had been absent from home, having been placed under the care of the kings uncles in order to be educated. When, having grown to manhood, he now returned to his fathers palace, his young stepmother, Phædra, fell violently in love with him; but Hippolytus failed to return her affection, and treated her with contempt and indifference. Filled with rage and despair at his coldness Phædra put an end to her existence; and when she was discovered by her husband she held in her hand a letter, accusing Hippolytus of being the cause of her death, and of having conspired against the honour of the king.

    Now Poseidon had upon one occasion promised to grant Theseus whatever request he should demand; he therefore called upon the sea-god to destroy Hippolytus, whom he cursed in the most solemn manner. The fathers awful malediction fell but too soon upon his innocent son; for, as the latter was driving his chariot along the sea-shore, between Troezen and Athens, a [267]monster, sent by Poseidon, rose out of the deep, and so frightened the horses that they became altogether unmanageable. As they rushed on in their mad career the chariot was dashed to pieces, and the unfortunate youth, whose feet had become entangled in the reins, was dragged along until life was nearly extinct.

    In this condition he was found by the unhappy Theseus, who, having ascertained the true facts of the case from an old servant of Phædra, had hastened to prevent the catastrophe. But he arrived too late, and was only able to soothe the last moments of his dying son by acknowledging the sad mistake which he had committed, and declaring his firm belief in his honour and innocence.

    After these events Theseus was persuaded by his friend Pirithöus, who had also about this time lost his young wife, Hippodamia, to join him in a journey through Greece, with the object of carrying off by force the most beautiful maidens whom they should chance to meet.

    Arrived at Sparta they beheld, in the temple of Artemis, Helen, the daughter of Zeus and Leda, who was engaged in performing sacred dances in honour of the goddess. Although the maiden was only nine years old the fame of her beauty, which was destined to play so important a part in the history of Greece, had already spread far and wide. Theseus and Pirithöus forcibly abducted her, and then having cast lots for her, she fell to Theseus, who placed her under the charge of his mother Æthra.

    Pirithöus now requested Theseus to assist him in his ambitious scheme of descending to the lower world and carrying off Persephone, the queen of Hades. Though fully alive to the perils of the undertaking Theseus would not forsake his friend, and together they sought the gloomy realm of Shades. But Aïdes had been forewarned of their approach, and scarcely had the two friends set foot within his dominions when, by his orders, they were seized, bound with chains, and secured to an enchanted rock at the entrance of Hades. Here the two friends languished for many years, until Heracles passed by in his search for Cerberus, when he released Theseus; but in obedience to an injunction of the gods, left Pirithöus to endure for ever the punishment of his too daring ambition.

    While Theseus was imprisoned in the under world Castor and Pollux, the brothers of Helen, invaded Athens, and demanded the restoration of their young sister. Seeing his country threatened with the horrors of warfare, an Athenian citizen named Academus, who knew of Helens place of concealment, repaired to the camp of the Dioscuri, and informed them where they would find her. Æthra at once resigned her charge, whereupon the brothers took leave of Athens, and, accompanied by Helen, returned to their native country.

    But the prolonged absence of Theseus gave rise to other troubles of a more serious character. Thinking the opportunity favourable for a revolt, a faction, headed by Menesthius, a descendant of Erechtheus, arrogated to themselves supreme power, and seized the reins of government.

    Returned to Athens, Theseus at once took active measures to quell the insubordination which existed on all sides. He expelled Menesthius from office, rigorously punished the ringleaders of the revolt, and placed himself once more upon the throne. But his hold upon the people was gone. His former services were all forgotten, and, finding at length that dissensions and revolts were rife, he voluntarily abdicated the throne, and retired to his estates in the island of Scyros. Here Lycomedes, king of the island, feigned to receive him with the utmost friendship; but being, as it is supposed, in league with Menesthius, he led the old king to the summit of a high rock, under pretence of showing him his estates, and treacherously killed him by pushing him over the cliff.

    Many centuries after his death, by the command of the oracle of Delphi, Cimon, the father of Miltiades, at the conclusion of the Persian war, brought the remains of Theseus, the great benefactor of Athens, to that city, and in his honour a temple was erected, which exists to the present day, and serves as a museum of art.

    THE DREAM OF LITTLE TUK Hans Christian Andersen Fairy Tales

    Ah! yes, that was little Tuk: in reality his name was not Tuk, but that was what he called himself before he could speak plain: he meant it for Charles, and it is all well enough if one does but know it. He had now to take care of his little sister Augusta, who was much younger than himself, and he was, besides, to learn his lesson at the same time; but these two things would not do together at all. There sat the poor little fellow, with his sister on his lap, and he sang to her all the songs he knew; and he glanced the while from time to time into the geography-book that lay open before him. By the next morning he was to have learnt all the towns in Zealand by heart, and to know about them all that is possible to be known.

    His mother now came home, for she had been out, and took little Augusta on her arm. Tuk ran quickly to the window, and read so eagerly that he pretty nearly read his eyes out; for it got darker and darker, but his mother had no money to buy a candle.

    "There goes the old washerwoman over the way," said his mother, as she looked out of the window. "The poor woman can hardly drag herself along, and she must now drag the pail home from the fountain. Be a good boy, Tukey, and run across and help the old woman, wont you?"

    So Tuk ran over quickly and helped her; but when he came back again into the room it was quite dark, and as to a light, there was no thought of such a thing. He was now to go to bed; that was an old turn-up bedstead; in it he lay and thought about his geography lesson, and of Zealand, and of all that his master had told him. He ought, to be sure, to have read over his lesson again, but that, you know, he could not do. He therefore put his geography-book under his pillow, because he had heard that was a very good thing to do when one wants to learn ones lesson; but one cannot, however, rely upon it entirely. Well, there he lay, and thought and thought, and all at once it was just as if someone kissed his eyes and mouth: he slept, and yet he did not sleep; it was as though the old washerwoman gazed on him with her mild eyes and said, "It were a great sin if you were not to know your lesson tomorrow morning. You have aided me, I therefore will now help you; and the loving God will do so at all times." And all of a sudden the book under Tuks pillow began scraping and scratching.

    "Kickery-ki! kluk! kluk! kluk!"—that was an old hen who came creeping along, and she was from Kjoge. "I am a Kjoger hen," [*] said she, and then she related how many inhabitants there were there, and about the battle that had taken place, and which, after all, was hardly worth talking about.

         * Kjoge, a town in the bay of Kjoge. "To see the Kjoge
         hens," is an expression similar to "showing a child London,"
         which is said to be done by taking his head in both bands,
         and so lifting him off the ground. At the invasion of the
         English in 1807, an encounter of a no very glorious nature
         took place between the British troops and the undisciplined
         Danish militia.

    "Kribledy, krabledy—plump!" down fell somebody: it was a wooden bird, the popinjay used at the shooting-matches at Prastoe. Now he said that there were just as many inhabitants as he had nails in his body; and he was very proud. "Thorwaldsen lived almost next door to me.* Plump! Here I lie capitally."

    * Prastoe, a still smaller town than Kjoge. Some hundred paces from it lies the manor-house Ny Soe, where Thorwaldsen, the famed sculptor, generally sojourned during his stay in Denmark, and where he called many of his immortal works into existence.

    But little Tuk was no longer lying down: all at once he was on horseback. On he went at full gallop, still galloping on and on. A knight with a gleaming plume, and most magnificently dressed, held him before him on the horse, and thus they rode through the wood to the old town of Bordingborg, and that was a large and very lively town. High towers rose from the castle of the king, and the brightness of many candles streamed from all the windows; within was dance and song, and King Waldemar and the young, richly-attired maids of honor danced together. The morn now came; and as soon as the sun appeared, the whole town and the kings palace crumbled together, and one tower after the other; and at last only a single one remained standing where the castle had been before,* and the town was so small and poor, and the school boys came along with their books under their arms, and said, "2000 inhabitants!" but that was not true, for there were not so many.

    *Bordingborg, in the reign of King Waldemar, a considerable place, now an unimportant little town. One solitary tower only, and some remains of a wall, show where the castle once stood.

    And little Tukey lay in his bed: it seemed to him as if he dreamed, and yet as if he were not dreaming; however, somebody was close beside him.

    "Little Tukey! Little Tukey!" cried someone near. It was a seaman, quite a little personage, so little as if he were a midshipman; but a midshipman it was not.

    "Many remembrances from Corsor.* That is a town that is just rising into importance; a lively town that has steam-boats and stagecoaches: formerly people called it ugly, but that is no longer true. I lie on the sea," said Corsor; "I have high roads and gardens, and I have given birth to a poet who was witty and amusing, which all poets are not. I once intended to equip a ship that was to sail all round the earth; but I did not do it, although I could have done so: and then, too, I smell so deliciously, for close before the gate bloom the most beautiful roses."

    *Corsor, on the Great Belt, called, formerly, before the introduction of steam-vessels, when travellers were often obliged to wait a long time for a favorable wind, "the most tiresome of towns." The poet Baggesen was born here.

    Little Tuk looked, and all was red and green before his eyes; but as soon as the confusion of colors was somewhat over, all of a sudden there appeared a wooded slope close to the bay, and high up above stood a magnificent old church, with two high pointed towers. From out the hill-side spouted fountains in thick streams of water, so that there was a continual splashing; and close beside them sat an old king with a golden crown upon his white head: that was King Hroar, near the fountains, close to the town of Roeskilde, as it is now called. And up the slope into the old church went all the kings and queens of Denmark, hand in hand, all with their golden crowns; and the organ played and the fountains rustled. Little Tuk saw all, heard all. "Do not forget the diet," said King Hroar.*

    *Roeskilde, once the capital of Denmark. The town takes its name from King Hroar, and the many fountains in the neighborhood. In the beautiful cathedral the greater number of the kings and queens of Denmark are interred. In Roeskilde, too, the members of the Danish Diet assemble.

    Again all suddenly disappeared. Yes, and whither? It seemed to him just as if one turned over a leaf in a book. And now stood there an old peasant-woman, who came from Soroe,* where grass grows in the market-place. She had an old grey linen apron hanging over her head and back: it was so wet, it certainly must have been raining. "Yes, that it has," said she; and she now related many pretty things out of Holbergs comedies, and about Waldemar and Absalon; but all at once she cowered together, and her head began shaking backwards and forwards, and she looked as she were going to make a spring. "Croak! croak!" said she. "It is wet, it is wet; there is such a pleasant deathlike stillness in Sorbe!" She was now suddenly a frog, "Croak"; and now she was an old woman. "One must dress according to the weather," said she. "It is wet; it is wet. My town is just like a bottle; and one gets in by the neck, and by the neck one must get out again! In former times I had the finest fish, and now I have fresh rosy-cheeked boys at the bottom of the bottle, who learn wisdom, Hebrew, Greek—Croak!"

    * Sorbe, a very quiet little town, beautifully situated, surrounded by woods and lakes. Holberg, Denmarks Moliere, founded here an academy for the sons of the nobles. The poets Hauch and Ingemann were appointed professors here. The latter lives there still.

    When she spoke it sounded just like the noise of frogs, or as if one walked with great boots over a moor; always the same tone, so uniform and so tiring that little Tuk fell into a good sound sleep, which, by the bye, could not do him any harm.

    But even in this sleep there came a dream, or whatever else it was: his little sister Augusta, she with the blue eyes and the fair curling hair, was suddenly a tall, beautiful girl, and without having wings was yet able to fly; and she now flew over Zealand—over the green woods and the blue lakes.

    "Do you hear the cock crow, Tukey? Cock-a-doodle-doo! The cocks are flying up from Kjoge! You will have a farm-yard, so large, oh! so very large! You will suffer neither hunger nor thirst! You will get on in the world! You will be a rich and happy man! Your house will exalt itself like King Waldemars tower, and will be richly decorated with marble statues, like that at Prastoe. You understand what I mean. Your name shall circulate with renown all round the earth, like unto the ship that was to have sailed from Corsor; and in Roeskilde—"

    "Do not forget the diet!" said King Hroar.

    "Then you will speak well and wisely, little Tukey; and when at last you sink into your grave, you shall sleep as quietly—"

    "As if I lay in Soroe," said Tuk, awaking. It was bright day, and he was now quite unable to call to mind his dream; that, however, was not at all necessary, for one may not know what the future will bring.

    And out of bed he jumped, and read in his book, and now all at once he knew his whole lesson. And the old washerwoman popped her head in at the door, nodded to him friendly, and said, "Thanks, many thanks, my good child, for your help! May the good ever-loving God fulfil your loveliest dream!"

    Little Tukey did not at all know what he had dreamed, but the loving God knew it.

    ANABOLISM AND CATABOLISM

    BIOCHEMISTRY:

    Biochemistry is a branch of Biology, which deals with the study of chemical components and the chemical processes in living organisms. A basic knowledge of biochemistry is essential for understanding anatomy and physiology, because all of the structures of an organism result from biochemical reactions. For example, photosynthesis, respiration, digestion, muscle contraction can all be described in biochemical terms.

    COVALENT BOND:

    Covalent bonds result when two or more atoms complete their electron shells by sharing electrons. When an electron pair is shared between two atoms, a single covalent bond is formed. An example is the bond between two hydrogen atoms to form a hydrogen molecule. Covalent bond stores large amount of energy.

    METABOLISM:

    All the chemical reactions taking place within a cell are collectively called metabolism. Metabolic processes are characterized as anabolism and catabolism.

    ANABOLIC AND CATABOLIC REACTIONS:

    Those reactions in which simpler substances are combined to form complex substances are called anabolic reactions. Anabolic reactions need energy. 



    Energy is released by the break down of complex molecules into simpler ones. Such reactions are called catabolic reactions. 


    Explanation Anabolic and catabolic reactions go side by side in the living cells. Complex molecules are broken down and the resulting smaller molecules are reused to form new complex molecules. Inter-conversions of carbohydrates, proteins, and lipids that occur continuously in living cells are examples or coordinated catabolic and anabolic activities. The survival of an organism depends upon its ability to take some chemicals from its environment and use them to make chemicals of its living matter. For this reason, cells of every organism are constantly taking in new cellular materials and obtaining energy for their needs. Life of an organism depends upon the endless chemical activities in its cells. This chemical activity is maintained with a high degree of organization.

    CLASSIFICATION OF PROTEINS BASED ON PHYSIOCHEMICAL PROPERTIES

    Based on proteins function, proteins may be classified as regulatory or hormonal proteins, structural proteins, transport proteins, genetic proteins and physiochemical proteins. But here, I am only going to define proteins based on physiochemical behaviorBased on physiochemical properties, proteins are classified into following types:
    • Simple Proteins
    • Compound or Conjugated Proteins
    • Derived Proteins


    Simple Proteins:
    These proteins on hydrolysis yield only amino acids or occasional carbohydrates and their derivatives. For example, albumins, globulins, lefumin, collagen, etc. Globulins are insoluble in water but soluble in dilute salt solutions. They are found in animals, e.g. lactoglobulin is found in muscles and also in plants. Legumin and collagen proteins are present in the connective tissues throughout the body. They are the most abundant proteins in the animal kingdom forming some 25-35 percent of body protein.

    Globulin 


    Compound or Conjugated Proteins:
    In these molecules the protein is attached or conjugated to some non-protein groups which are called prosthetic groups. For example, phospho-proteins are conjugated with phosphoric acid; lipoproteins are conjugated with lipid substances like lecithin, cholesterol and fatty acids.




    Derived Proteins:
    As the word “derived” is showing that this class of protein includes substances which are derived from simple and conjugated proteins. For example, proteoses enzymes, peptones, oligopeptides, polypeptides, etc.


    Polypeptide chain

    What Is The Issue With Ireland

    Let me specify it once again,even though I have told this earlier.I am not a Catholic (not even a Catholic Marxist),I am not a Protestant,I am just a mere human being (who is a Marxist) from India,Asia.I do not think I belong to any religion like that at all,so you can consider my judgement neutral. 
    So,let us see this from the angle of secularism first.The misery practised by almost all Roman Catholics until the sixteenth century is unbearable and intolerable.I agree.Until Martin Luther came up with his thesis and hung it in front of the Wittenberg Church in 1517,the misery might not have just stopped.The way they hung Menocchio for just coming up with a new way of decoding the Bible is a huge crime.You have to let people interpret God the way they wish to.And even if a million other people today do not agree with my philosophy,there is another million who do - and even if there is no other individual who think alike me in any way(just for the sake of the analogy), I am free to think what I want to think and I ought to have full right to speak it aloud.These thoughts ultimately contribute to a collective ideology called democracy.We will not go about Economics at the moment to keep us focused on what we are dealing with.This topic will be discussed in the next topic,that is the post to be brought up next day. 
    The second thing that we will try to look at if Politics and Religion can be separated in such an utopian manner.Many scholars believe that it is not possible and if you look at it logically,then it truly will never be possible.What do we do,then?All that can be done is give people belonging to different religions as well as different sectors within the religion a sense of equality.It must be seen that none feels alienated.Forced integration is a very,very negative social factor causing even riots and violence in certain cases.This is exactly what was not done in Ireland.What actually happened was the Protestants had a much better economic condition and as a result,a better social position.The Catholics are poorer,more prone to belong to the lower and downtrodden section of the society.What is even more annoying for them is that Ireland was a largely Catholic country.England tactfully (Ah yes,tactful - as they always are!) ensued the Protestant population and incited them to form a base in Ireland,to have a stronger hold and say over United Kingdom.They have shown a lot more tactful approach towards Scotland as well,but what they did towards the Irish and especially the Irish Roman Catholics somehow looks like a very wrong and negative incident to the eye.I remember looking at a poster in our Political Science book which read - "No Dogs.No Blacks.No Irish."How odd,how insane and how insensitively idiotic is that?
    The third thing is that what the case is with Northern Ireland and what actually is their demand.The Northern part of Ireland ultimately started an armed revolt against the Unionists.They wanted to join with The Republic of Ireland (which was formed long back in 1937 and ultimately named The Republic of Ireland in 1948) but they actually accepted a peace treaty,or rather were compelled to do so.

    The Two Irelands : Northern Ireland and Republic of Ireland


    The Flag of The Republic of Ireland

    There were a lot of reasons behind the revolt,though.The Irish were prohibited from wearing their traditional dress,speak in Gaelic language or spread their own culture independently so that the British could carry on their own monopoly decisions practically over the socio-political conditions of the United Kingdom.This is where a certain sector of the religion - that is,the Catholics who wanted their separate identity to retain,which was obviously logical.The Protestants were conservative and remained submissive to the command of England.The war took lives,but when it comes to violence on the linguistic and cultural sentiments,people are bound to get emotionally devoted to sustain their own culture.And what the Unionists were trying to do was not justified,either.That you will be forced to sing the national anthem in a different language just because a certain powerful sector is dictating to do so cannot be justified.
    Coming to the second fact that we have talked about,the economy,the Catholics are poorer economically than the Protestants and that is quite possibly where the concept of Catholic Marxism finds a place in the political scenario of Europe.Now,that is strange to me because I dont know how something as independent and as secular as Marxism can be opted for by a certain sector of a religion.
    Looking at the distribution of the economy in the current years,the number of poor is continuously increasing in Northern Ireland. (Reference : http://www.ofmdfmni.gov.uk/child-working-age-poverty-update-jan-2014.pdf)The economical conditions are marginally better in the Republic of Ireland.(Reference : http://www.thejournal.ie/report-700000-living-in-poverty-in-ireland-412250-Apr2012/)
    What really is a stake here is that a part of the Irish are socially stable and happy to practise their own culture whereas a part still faces injustice.However,I do not think you can forcibly change the culture of an entire group.As for the Republic of Ireland,it fills us with a certain warmth that the pure Irish culture is never going to vanish.

    Cellulose What is Cellulose

    Cellulose is a carbohydrate that does not change chemically during the human digestive process. Since  cellulose is indigestible, it passes through the intestinal tract unchanged.
    Cellulose is present in fiber-containing foods, such as green vegetables, fruits, and whole-grain wheat bread.
    Cellulose aids in the elimination of waste products from the intestine, and for this reason, it is sometimes used in the treatment of constipation.

    People Are The Ones

    The title of this post is inspired by Jean Jacques Rousseaus philosophy on people during the French Revolution.Looking at the Russian Revolution and looking at the way they removed the Tsar,looking at the Napalm used in the Vietnam War and yet,when the Vietnamese won,looking at the way the Chinese took power,looking at every part of how people arose for communism/socialism/true democracy,I find people are the ones who ultimately rule.And if you get them raged,its your responsibility to bear their rage as well.Thats what Trinomool Congress Party has got to do.Pay back - pay back to the millions for whom a mere  6,000 (About $ 1000) is the ultimate riches of their life. Instead of helping these chit funds and trying to cover up your misdeeds,you should have tried to pay back (You know,the other way is always there) Pay back these families where the daughter has been raped and you have given shelter to the goons involved.Pay back to those young people who have come from a middle class/poor family to give exams for getting jobs and later have found the names were already paneled for only TMC candidates.Pay back the lives of those Leftist workers whom you have murdered.Pay back those broken party offices.Pay back for this antidemocratic rulePay back the entire amount which according to me cannot even be estimated. And now comes the topic,rigging.Rigging in booths,Shooting CPI(M) party workers and even not leaving the Congress/BJP workers at some places,but the leftists are the most affected.Just what happened to our State President of DYFI (Democratic Youth Foundation of India) is intolerable. Just what you did to Sudipto Gupto (SFI Leader) is intolerable.Just what you did to those hundreds of Leftist workers/supporters is intolerable.Just what you did to those thousands of Party Offices of ours is intolerable.Rigging and trying to break the camera of journalists or shooting other party workers or scaring people is not the way.You will have to pay back for all these factors.Its people who rule,this truth must be realised and its this people whom you are getting frustrated - I just can say this wont help for a long time.Red cannot be killed like that because THE HAMMER AND SICKLE IS STRONGER THAN AN AK-47,MORTAR,TANK OR A NUCLEAR BOMB.

    Ileitis Causes Symptoms Treatment What is Ileitis



    Ileitis is an inflammation of the third portion of the small intestine (Ileum), often also involving the colon.
    Ileitis affects males and females equally, usually under the age of 40.

    Ileitis causes

    Ileitis may result from infection, previous bowel surgery, or, most commonly, an immunologic factor.

    Ileitis symptoms

    The condition usually causes acute abdominal pain, similar to appendicitis. Other symptoms of Ileitis include diarrhea (sometimes alternating with constipation), fever, anorexia, weight loss, and a distention of the abdomen.

    Ileitis treatment

    No specific treatment has been discovered for Ileitis. Sometimes a complete recovery will follow an initial isolated attack of acute ileitis. More commonly, the disease is chronic, in which case various drugs can help reduce the symptoms.
    A bypass operation or the removal of the affected bowel can also diminish the symptoms, though surgery will not eliminate the condition.

    First Bank In The World When was the first bank established in the world

    Today banks provide a variety of services, but they actually have two main tasks.
    The first task is to accept deposits from people and keep their money until they need them again.
    The second task is to give money loans to people that they are willing to pay back with interest.
    Having this definition in mind, we can say that the banking is old as mankind.
    In ancient Babylon, Egypt and Greece people were engaged in banking. The temples were usually the place where the money were deposited.
    In Rome, in 210 BC with decree published by the Forum, the location of the money changers was determined.
    However, in the Middle Ages, taking interest was considered a sin, and some countries have banned their citizens to establish a bank.
    Of course, some people were still doing it.
    Thus, in the Middle Ages money changers in Italy did their business on the street, on the bench, which on Italian is called “banco”, and hence came the name "bank".

    When was the first bank established in the world?

    Modern banking first emerged in Venice in 1587, when the “Banco di Rialto” was founded. The bank received deposits and allowed the investors to write checks based on money they had in the bank. In 1619 “Banco del Giro” took over “Banco di Rialto” and started to give receipts on the invested silver and gold, which were used as a cash receipts.
    Bank of Amsterdam, founded in 1609, also issued certificates which were used as a "banks money."
    In England the jewelers were also bankers until 1694, when the Bank of England was founded, which held a monopoly on public banking in England until 1825.

    Goodnight Moon Goodnight Picture Books

    The New York Times has started a tempest in a teapot with its October 7th article "Picture Books No Longer a Staple for Children." To summarize, picture books arent selling well and consequently publishers are producing fewer of them. The reason? The current economic climate doesnt help, of course, nor does the growing number of digital playthings at a childs disposal. But another major component, according to the article, is that parents (by which they middle-class parents) dont see picture books as relevant and are pressuring their offspring into ditching them to read chapter books. The thinking being: Why bother with Little Miss Spider when you can go straight to Charlottes Web and from there its a hop, skip, and a jump into Harvard?

    To back up its claim, the article quotes bookstore owners and managers, book buyers, publishing executives, and childrens publishers. One parent, a mother of three boys and writer of the book blog Zen Leaf, said of her six year old son, a reluctant reader, "He would still read picture books if we let him, because he doesnt want to work to read." (She has since written a post saying her comment was taken out of context.)

    Its a nice theory, but, sorry, Im not buying it. Picture books have been a hard sell (ask any picture book author) for years now. And while no doubt there are some parents who would rather their kids peruse the Wall Street Journal rather than The Wolves in the Wall, these types of parents have always existed. No. The reason for the picture books decline is--hold on to your hats--they cost too much! A hardcover picture book is priced around $18. You can buy a paperback chapter book for under $10. Its a no-brainer. And when picture books are purchased, they are usually bought as gifts, and the choice is likely to be a classic, such as The Runaway Bunny or Where the Wild Things Are. Its too expensive to take a chance with an unknown book that the child might glance at once and never again.

    When my daughter was young, we used to visit the library for picture books and buy others when they came out in paperback or in book clubs. (Though nothing beats a hardcover edition, I admit.) Nowadays, libraries are seeing their budgets slashed and cant afford to buy as many picture books, or indeed, any type of book. Im not sure what the answer is, but my guess is that once the economy rebounds (or if) so will picture books. Fingers crossed.

    Why? Readers get a front view seat to the Macys Thanksgiving Day parade and how it began in this award-winning nonfiction picture book.

    5. Anna Hibiscus by Atinuke

    Why? Atinuke is a natural storyteller. Anna, a young African girl, is an engaging character who lives with her extended family in an unnamed African village.

    6. The No. 1 Car Spotter by Atinuke

    Why? An eyeopener into the world of a young African boy and his extended family.

    7. Toys Come Home by Emily Jenkins

    Why? This hard-to-classify story stayed with me long after I read it.

    8. Bad Kitty Meets the Baby by Nick Bruel

    Why? One word--Hysterical. Bad Kitty rules.

    9. Duck, Death and the Tulip by Wolf Erlbruch

    Why? A picture book about death like no other. Wow.

    Spinster Goose Twisted Rhymes for Naughty Children

    Gum chewers, thieves, liars, cheats, some children are too naughty for Mother Goose to handle. So she ships these troublemakers off to her sisters school for wayward brats. Spinster Goose runs a tight ship and doesnt tolerate misbehavior.

    The pinchers get pinched,
    and the pokers get poked.
    The biters get bit,
    and the smokers get smoked.
    The takers get taken.
    The sordid get sore.
    The shakers get shaken
    right down to their core.

    Lisa Wheeler has taken familiar rhymes from Mother Goose and subverted them. Readers will delight in finding their favorite characters in new guises. Mary still brings her lamb to school, but the young lady is a big fibber and claims her pet is a horse. Jack and Jill ditch class to climb that hill, and Little Miss Muffet dines on chalk, not curds and whey. All get their comeuppance. Sophie Blackalls sublime illustrations are worth the price of admission alone. She must have been channeling Edward Gorey when she drew her cast of ghastly characters. Great fun!
