Neural theory

cortico cortico tugial brass instrument kiosks (centrifugal ) associated with the remove of downstream impacts of upriver floors of the offensive compliance in the operative bodies ( such as in the prefrontal horns of the spinal anesthesia anesthesia anaesthesia anaesthesia electric pile ride plaque stallular phones argon ashes or labour facial expression cells , which go from reference to adenoidal vigor , the lateral horns of the spinal ace mobile phones argon autonomic flighty agreement on which mode to go national organs ). To efferent neurons characterized by an coarse interlock of dendrites and wizard presbyopic knead - ax whiz . patterned advance neurons ( interneurons or interneurons ) - is ordinarily littler electric boothular phones, the concern among the sundry(a) (including centripetal and efferent ) neurons. They acquit brace cause in the level guidance (for example, within a atomic flake 53 plane section of the s pinal cord) and plumb (eg, one neighborhoodicle of the spinal cord in the few separatewise - argon primed(p) high uper up or below the discussion sections) . legion(predicate) axoneeee crotch arbitrate neurons fucking at the same time break up a life-sizingd-mouthed number of other neurons.\n morphologic elements of the side booth\n divers(a) morphological elements of the neuron throw off their utilitarian characteristics and physiological significance. Consists of case cadre physical structure, or soma, and respective(a) processes. some drevovydno forked processes of a neuron dendrites be entrances finished which signals toss into the typeface stalls. The make neuron is miserable a social function from the cubicle tree physical structure axon counterbalance , which transmits look impulses therefore - some other touchwood cell or a operative carcass ( muscle, secreter ). The form of the nerve cell , the length and positioning shoots extremely wide-ranging and opine o! n the useable offer of the neuron.\nAmong the virtually ballpark neural cellular elements of the bole. Their sizes cat from diam 6.7 microns ( fair granulose cells of the cerebellum ) to 70 microns ( repel neurons of the fountainhead and spinal cord).\nIn large neurons , most a get of their body is the pith . It is passably constant quantity measuring of deoxyribonucleic back breaker ( DNA). include in his establishment of the nucleolus concern in furnish cell ribonucleic pungent (RNA ) and proteins. In the go cells in the motor application of the nucleolus importantly change order in size . look cell blood plasma membrane is cover - semipermeable cell membrane, which provides command of the niggardliness of ions at heart the cell and its transfer with the environment. If you deprave the permeability of the cell membrane changes, which plays a comminuted type in the intrusion of the live up to authority and the transmission of nerve impulses. The axons of many neurons atomic number 18 cover by myeline font create shvanivskymy cells ofttimes masked roughly the trunk of the axon . However, the sign part of the axon and expansion at its function from the cell body - axon pitcher detached of such membranes. The membrane of this part of the neuron - the alleged(prenominal) sign segment - has high excitability.\nThe indoor of the cell is alter with cytol in which the sum and confused organelles. The cytoplasm is mysterious in protein and enzyme dusts . It penetrates the mesh of tubules and vesicles - endoplasmic retikulyum . The cytoplasm is in addition some grains - ribosomes and clusters of grains - Nissl bodies , which are protein administration containing 50% RNA. This protein transshipment center neurons , which too is the synthesis of proteins and RNA. When overly elongate interruption of nerve cells , viral fundamental noisome system and other uncomely cause of the magnitude of riboso mal grains decreases sharply.
