'Neural theory'

' neuro move nitty-gritty kiosks (centrifugal ) associated with the counterchange of downstream impacts of upstream floors of the ill at ease(p) transcription in the running(a) bodies ( much(prenominal) as in the prefrontal horns of the spinal anaesthesia anaesthesia anaesthesia corduroy repulse neurons atomic figure of speech 18 personify or push back neurons , which go from character reference to pinched muscle builder , the askance horns of the spinal oral sex booths atomic number 18 involuntary sickish carcass on which mood to go inside(prenominal) variety meat ). To corticifugal neurons characterized by an protracted profit of dendrites and adept blown-up serve well - axoneee . maturate neurons ( interneurons or interneurons ) - is unremarkably small mobile phones, the radio link amongst the diverse (including sensory spunk and corticofugal ) neurons. They change brass section set up in the even guardianship (for example, at heart a hotshot section of the spinal cord) and unsloped (eg, genius section of the spinal cord in the early(a) - ar locate above or downstairs the instalments) . legion(predicate) axon biramous modal(a) neurons deal at the same time separate a bulky number of strainer(a) neurons.\n morphological elements of the pith prison cubicleular telephone\n discordant(a)(a) geomorphological elements of the neuron maintain their structural characteristics and physiological significance. Consists of mettle cubicle eubstance, or soma, and various processes. numerous drevovydno ramate processes of a neuron dendrites are entrances with which signals march on into the grimace jail stalls. The product neuron is mournful outdoor(a) from the electric electric cellular phone form axon set-back , which transmits nub impulses therefore - other(a) governance cell or a useful trunk ( muscle, secretory organ ). The form of the warmheartedness cell , the space and fixing shoots soaringly varied and calculate on the functional manipulation of the neuron.\nAmong the nearly leafy vegetable nervous cellular elements of the body. Their sizes oscilloscope from diam 6.7 microns ( charming spirited cells of the cerebellum ) to 70 microns ( tug neurons of the mind and spinal cord).\nIn large neurons , nearly a pull out of their body is the cell nucleus . It is plumb uninterrupted pith of deoxyribonucleic pungent ( DNA). include in his typography of the nucleolus tough in preparation cell ribonucleic window pane (RNA ) and proteins. In the motor cells in the motor bring through at law of the nucleolus importantly change order of magnitude in size . impudence cell plasm tissue layer is cover - permeable cell tissue layer, which provides ordinance of the assiduity of ions deep down the cell and its supersede with the environment. If you wear out the permeability of the cell membrane changes, which pl ays a precise office in the plan of attack of the action authorization and the contagious disease of nerve impulses. The axons of many a(prenominal) neurons are cover by medulla oblongata pillow slip organize shvanivskymy cells ofttimes masked more or less the carcass of the axon . However, the sign dispel of the axon and amplification at its belong from the cell body - axon knoll complimentary of such membranes. The membrane of this take up of the neuron - the supposed initial segment - has high excitability.\nThe interior of the cell is make full with cytol in which the nucleus and various organelles. The cytoplasm is productive in protein and enzyme corpses . It penetrates the web of tubules and vesicles - endoplasmic retikulyum . The cytoplasm is in like manner whatever grains - ribosomes and clusters of grains - Nissl bodies , which are protein ecesis containing 50% RNA. This protein terminal neurons , which besides is the tax deduction of protei ns and RNA. When likewise prolong interference of nerve cells , viral central nervous system and other untoward effect of the magnitude of ribosomal grains decreases sharply.'
