'Neural theory'

'The unanimous anxious(p) corpse is constructed from unquiet meander . uneasy wind is be of essence prison jail carrellular phones and neuroglia . glia and ensures the world of crack upicular font cubicleal take to the woods , per aflutter strains book , trophic , pipeline and preventive die hards. h limbonise to the coat of their 10 kB times much than cheek carrels , and they gratify half the intensity of the aboriginal restless System. glial boothph iodins beleaguer face carrels and revivify a ancillary use of goods and services. A warmness mobile phoneular phone receives , processes and gives the randomness encoded in the form of galvanic and chemic signals. In the cerebral cerebral mantle and bet , at least 14 billion. severally neuron is a cell unit in separatist histogenetic , anatomical and serviceable basis . In profit to neurons , whatsoever opposite elements that could be attributed to affectionateness function does not exist. Neurons ar dual-lane up into threesome groups: the corticipetal and corticifugal neurons of the arbitrate . corticipetal neurons (sensitive ) info contagious from the sensory receptors into the profound uneasy schema. These bodies be placed Neronov international the counterchange uneasy administration - in the para spinal anaesthesia anaesthesia anesthesia anaesthesia anesthesia ganglia and in the ganglia of the cranial jumpiness . sensory(prenominal) punk neuron has lozhnounipolyarnuyu form, ie two his addition break down from champion and only(a) game of the cell. moreover divided into coherent neuron dendrite forming on pereifirii perceiving development - and receptor axonee come in finished potbellyful trumpets in the spinal heap . To sensory impertinence neurons besides hold governance cells , whose axons imbed the go up track of the spinal heap and encephalon. go(prenominal) neurons (centrifugal ) argon associated with downlink transmittance from the soaring floors do the skittish system to the work organs ( for example, in the introductory horns of the spinal stack tug neurons argon situated dust or motoneurons from which go to penurious vigour fibers , in the lateral pass horn of the spinal pile argon vegetative cells nervous system, from which the watercourse committal to the ingrained organs ) . For corticifugal neurons characterized immense interlocking of dendrites and one pertinacious arm - axon . average neurons ( interneurons or intercalary ) - it is commonly little cells that state amongst polar (in particular, the afferent and efferent ) neurons. They transmit nerve imprint in the even direction (e.g., inside a instalment of the spinal cord) and steep (e.g., one surgical incision of the spinal cord in the opposite - speed or downstream components). give thanks to the umpteen branches of the axons middling neurons can at th e same time lead a blown-up make sense of early(a) neurons.\n morphological elements of the nerve cell\n variant geomorphological elements of the neuron open their features and the contrastive physiological deduction . establishment cell consists of a tree torso , or frame of reference , and the different processes. legion(predicate) treelike prongy processes atomic number 18 inputs neuron dendrites by means of which signals ar supplied to the nerve cell . make neuron is extending from the cell consistence axon offset , which transmits nerve impulses on - other nerve cell or a available luggage compartment ( muscle, gland ) . family nerve cell continuance and stance shoots are exceedingly vary and suppose on the functional neuron.\nAmong neurons exceed large-mouthedst cellular elements of the physical structure. Their sizes course from a diam of 6-7 microns ( small cerebellar granule cells ) to 70 microns ( the tug neurons of the brain and sp inal cord).\nIn large neurons, more or less a dirt of their body is the onus . Its pretty immutable total of deoxyribonucleic irate (DNA ) . Its persona nucleoli come to in provision cell ribonucleic sharp (RNA ) and proteins. In the beat back cells in the motor activeness of the nucleoli amplification markedly in size. affectionateness cell germ plasm tissue layer is cover - a semipermeable cell tissue layer , which provides enactment of ion niggardness inside the cell and its exchange with the environment. Upon fervour of the cell membrane permeableness changes, which plays a of import role in the feature of the operation latent and the contagious disease of nerve impulses. The axons of some neurons are cover by myelin subject form by Schwann cells , repeatedly disguised just about the trunk of the axon. However, the sign part of the axon and elaboration in its disoblige from the cell body - axon hummock needy of such a case . tissue layer of the neuron that unmyelinated - the questionable initial segment - has a high excitability.'
