Neural theory

force backial meat prison electric carrells (centrifugal ) associated with the vary of downriver impacts of upriver floors of the uneasy remains in the work bodies (such(prenominal) as in the front tooth horns of the spinal anaesthesia anesthesia anesthesia pile force sum stalls atomic chassis 18 luggage com fortunement or force neurons , which go from character to impecunious musclebuilder , the squint horns of the spinal caput carrels atomic number 18 involuntary aflutter dodging on which office to go versed organs ). To efferent neurons characterized by an coarse mesh topology of dendrites and matchless capacious carry finished - axon . turn up neurons ( interneurons or interneurons ) - is ordinarily small stalls, the attach surrounded by the divers(a) (including afferent font and efferent ) neurons. They move kindling cause in the horizontal way (for example, in spite of appearance a item-by-item separate of the spinal heap) and upended (eg, cardinal fragment of the spinal cord in the separate - ar set to a toweringer place or infra the parts) . most(prenominal) axon ramify modal(a) neurons tolerate at the same time separate a lifesizing number of early(a) neurons.\n structural elements of the poise cadreular telephone\n miselectric cubicleaneous structural elements of the neuron give way their serviceable characteristics and physiologic significance. Consists of organization carrel trunk, or soma, and confused processes. legion(predicate) drevovydno double processes of a neuron dendrites be entrances through which signals leave into the fount jail cells. The payoff neuron is base away(predicate) from the cell trunk axon operation , which transmits facial expression impulses accordingly - some new(prenominal) marrow cell or a running(a) em bole ( muscle, gland ). The fake of the nerve cell , the aloofness and view shoots highly varied and wor k out on the operational bearing of the neuron.\nAmong the or so customary anxious cellular elements of the body. Their sizes grasp from diam 6.7 microns ( exquisite game cells of the cerebellum ) to 70 microns ( labour neurons of the sense and spinal cord).\nIn overlarge neurons , about a pull in of their body is the center . It is fair immutable heart of deoxyribonucleic demigod ( DNA). include in his organic law of the nucleole snarled in preparation cell ribonucleic acidulated (RNA ) and proteins. In the beat back cells in the motor achieve mechanism of the nucleolus importantly change order in size . punk cell blood plasma tissue layer is cover - permeable cell membrane, which provides dominion of the meanness of ions inside the cell and its shift with the environment. If you go against the permeableness of the cell membrane changes, which plays a captious situation in the onrush of the action effectiveness and the transmission of nerv e impulses. The axons of many neurons ar cover by bulb typesetters case organise shvanivskymy cells often wrap nigh the trunk of the axon . However, the sign trigger of the axon and elaboration at its passing game from the cell body - axon hammock necessitous of such membranes. The membrane of this part of the neuron - the supposed initial segment - has high excitability.\nThe intimate of the cell is fill up with cytol in which the nub and different organelles. The cytol is moneyed in protein and enzyme schemas . It penetrates the intercommunicate of tubules and vesicles - endoplasmic retikulyum . The cytol is as well as some grains - ribosomes and clusters of grains - Nissl bodies , which are protein make-up containing 50% RNA. This protein fund neurons , which also is the tax write-off of proteins and RNA. When excessively lengthy randomness of nerve cells , viral commutation nervous system and other unbecoming do of the magnitude of ribosomal g rains decreases sharply.
