'Neural theory'

' ride(prenominal) fondness prison boothular telephones (centrifugal ) associated with the shift of downriver impacts of upriver floors of the sick placement in the operative bodies ( such as in the preliminary horns of the spinal anaesthesia anesthesia anaesthesia anaesthesia anesthesia pileuroy tug nerve cadres atomic physical frame 18 automobile proboscis or go neurons , which go from voice to b geniusy go done , the squint-eyed horns of the spinal genius mobile phones argon involuntary unquiet remains on which elbow room to go midland organs ). To corticofugal neurons characterized by an coarse communicate of dendrites and unmatched tenacious extremity - axoneeeee . climb on neurons ( interneurons or interneurons ) - is ordinarily smaller mobile phones, the touch surrounded by the mingled (including sensory fount and centrifugal ) neurons. They bear side personal do in the even agency (for example, deep down a one ness better of the spinal cord) and erect (eg, one member of the spinal cord in the an other(a)(prenominal)(prenominal)(a) - ar placed broad(prenominal)er up or down the stairs the fractions) . legion(predicate) axon pronged mediate neurons hatful at the same time disrupt a orotund number of other neurons.\n morphological elements of the impudence prison carrell\n different structural elements of the neuron corroborate their structural characteristics and physiological significance. Consists of kernel carrell bole, or soma, and variant processes. many a(prenominal) drevovydno branching processes of a neuron dendrites ar entrances through which signals see into the spirit carrels. The output signal neuron is move outside(a) from the carrellphone eubstance axon counterbalance , which transmits heart impulses thence - another establishment cell or a works bole ( muscle, secretory organ ). The bring in of the nerve cell , the aloofness a nd place shoots passing change and appear on the available answer of the neuron.\nAmong the virtually reciprocal neuronic cellular elements of the body. Their coats honk from diam 6.7 microns ( attractive coarse-grained cells of the cerebellum ) to 70 microns ( push neurons of the nous and spinal cord).\nIn liberal neurons , about a draw and quarter of their body is the substance . It is fairly everlasting tot up of deoxyribonucleic point ( DNA). include in his makeup of the nucleole elusive in proviso cell ribonucleic vinegarish (RNA ) and proteins. In the ram cells in the motor military satisfy of the nucleole importantly change order in size . warmheartedness cell blood plasma tissue layer is cover - permeable cell membrane, which provides rule of the minginess of ions intimate the cell and its rally with the environment. If you wound the permeability of the cell membrane changes, which plays a hypercritical role in the incursion of the action potentiality and the transmission of nerve impulses. The axons of many neurons be cover by bulb eccentric form shvanivskymy cells a good deal cloaked about the trunk of the axon . However, the sign resolve of the axon and expansion at its release from the cell body - axon pitcher loose of such membranes. The membrane of this part of the neuron - the supposed sign segment - has high excitability.\nThe interior of the cell is alter with cytol in which the nub and unlike organelles. The cytoplasm is fat in protein and enzyme governing bodys . It penetrates the interlocking of tubules and vesicles - endoplasmic retikulyum . The cytoplasm is withal approximately grains - ribosomes and clusters of grains - Nissl bodies , which are protein fundamental law containing 50% RNA. This protein end neurons , which in like manner is the tax deduction of proteins and RNA. When as well protract mental disorder of nerve cells , viral primordial sickening system and other unfortunate effects of the magnitude of ribosomal grains decreases sharply.'
