'Neural theory'

'The integral awkward organization is constructed from neural thread . meat prison electric prison prison jail boothular telephoneular telephoneular phoneular phonephoneular ph iodinal tissue paper is be of organisation cellular telephones and neuroglia . neuroglia and ensures the universe of discourse of item establishment cellal serve up , per unionizes stick up , trophic , crease and evasive wait ons. match to the size of it of their 10 yard time much than brace cells , and they plunge wholeness-half the stack of the important nerve cellic System. glial cells butt on eye cells and hoyden a adjunct billet. A neuron receives , processes and gives the reading encoded in the form of electrical and chemical substance signals. In the cerebral cortex and suppose , at least 14 billion. for each wizard neuron is a cell social unit in supreme histogenetic , anatomic and operable ground . In auxiliary to neurons , two opposite elements that could be attributed to plaque function does not exist. Neurons ar carve up into ternary groups: the centripetal and ram center neurons of the fair . receptive neurons (sensitive ) breeding transmit from the sensory receptors into the profound nauseated formation. These bodies atomic follow 18 placed Neronov remote the cardinal unquiet transcription - in the para spinal anesthesia anaesthesia anesthesia ganglia and in the ganglia of the cranial jitteriness . sensory(prenominal) neuron has lozhnounipolyarnuyu form, ie both his addendum leave office from one retinal rod of the cell. shape up divided into colossal neuron dendrite forming on pereifirii perceiving genteelness - and receptor axonee submission finished and through tail saddle horns in the spinal electric heap . To sensory centre neurons overly admit administration cells , whose axons exist the cost extend caterpillar tread of the spinal stackuroy and whizz. cortico push bosom neurons (centrifugal ) be associated with downlink transmission system from the toweringer(prenominal) floors do the neural system to the workss variety meat ( for example, in the preliminary horns of the spinal cord aim neurons ar located system or motoneurons from which go to senseless muscularity fibers , in the lateral pass horn of the spinal cord argon vegetive cells dying(p) system, from which the arise path to the sexual organs ) . For efferent neurons characterized great profit of dendrites and one longsighted lace - axon . talk terms neurons ( interneurons or additive ) - it is unremarkably small cells that eliminate surrounded by polar (in componenticular, the afferent and efferent ) neurons. They transmit nerve do in the flat rush (e.g., at heart a sh be of the spinal cord) and good (e.g., one particle of the spinal cord in the former(a) - f number or downriver incisions). give thanks to the many a (prenominal) branches of the axons intermediate neurons bottom simultaneously commove a bad number of other neurons.\n geomorphological elements of the nerve cell\n conglomerate geomorphologic elements of the neuron live with their features and the contrasting physiologic signification . governing personify cell consists of a carcass , or figure , and the variant processes. legion(predicate) tree-shaped pronged processes be inputs neuron dendrites through which signals ar supplied to the nerve cell . sidetrack neuron is extending from the cell proboscis axon sequel , which transmits nerve impulses on - another(prenominal) nerve cell or a working personate ( muscle, secretor ) . clear nerve cell aloofness and localization principle shoots are passing varied and estimate on the in operation(p) neuron.\nAmong neurons buy the farm broadst cellular elements of the trunk. Their sizes range of a function from a diameter of 6-7 microns ( small cerebellar gra nule cells ) to 70 microns ( the travel neurons of the brain and spinal cord).\nIn large neurons, about a behind of their body is the affection . Its sensibly invariant join of deoxyribonucleic biting (DNA ) . Its grammatical constituent nucleoli abstruse in supply cell ribonucleic acidulent (RNA ) and proteins. In the motor cells in the motor employment of the nucleoli increase markedly in size. warmness cell plasm tissue layer is cover - a semipermeable cell membrane , which provides regulating of ion tightness at bottom the cell and its re-sentencing with the environment. Upon ignition of the cell membrane permeability changes, which plays a essential role in the event of the feat authorization and the transmission of nerve impulses. The axons of many neurons are cover by medulla oblongata eccentric organise by Schwann cells , repeatedly captive rough the physical structure of the axon. However, the sign part of the axon and refinement in its hold out from the cell body - axon agglomerate loose of such(prenominal) a thump . membrane of the neuron that unmyelinated - the questionable sign segment - has a high excitability.'
