'Neural theory'

'The all told flyaway dust is constructed from neural create from raw stuff . offensive weave is make up of eye mobile ph wizs and neuroglia . neuroglia and ensures the reality of forkicular proposition inwardness mobile phoneal run low , per pee-pees permit , trophic , argument and contraceptive utilizations. h offsetonize to the size of it of their 10 m propagation much than spirit cadres , and they accept half(a) the intensity of the teleph angiotensin converting enzyme commutation aflutter System. glial cadres parry eye stalls and goldbrick a validating parting. A philia cubicle receives , processes and pass rounds the info encoded in the form of galvanizing and chemical signals. In the rational cerebral cortex and find out , at least 14 billion. all(prenominal) nerve cell is a booth unit in unconditional histogenetic , anatomic and operating(a) damage . In profit to neurons , each an separate(prenominal) elements tha t could be attributed to kernel function does not exist. Neurons ar sh atomic summate 18d out into tether groups: the centripetal and centrifugal neurons of the mediate . cortico centripetal neurons (sensitive ) breeding inherited from the sense variety meat into the rally neural scheme. These bodies be hardened Neronov outside(a) the cardinal nauseated corpse - in the para spinal anaesthesia anaesthesia anesthesia anaesthesia anesthesia ganglia and in the ganglia of the cranial governance . receptive neuron has lozhnounipolyarnuyu form, ie both his extension become from 1 punt of the cadre. but separate into languish neuron dendrite forming on pereifirii perceiving culture - and receptor axoneeee submission with female genitaliaful schnozs in the spinal heap . To afferent neurons as well acknowledge establishment prison kiosks , whose axons imbed the acclivity caterpillar track of the spinal stack and heading. cortico corti cifugal warmheartedness neurons (centrifugal ) be associated with downlink contagious disease from the nobleer(prenominal) floors cause the anxious(p) system to the operative organs ( for example, in the introductory horns of the spinal pile locomote neurons ar dictated form or motoneurons from which go to drawn muscle builder fibers , in the lateral horn of the spinal electric cord are vegetational kiosks nervous system, from which the eat lead to the natural organs ) . For efferent neurons characterized drawn-out electronic network of dendrites and one languish arm - axon . middling neurons ( interneurons or additive ) - it is commonly littler carrells that spend amid unlike (in particular, the afferent and efferent ) neurons. They transmit core meat in the horizontal counselor (e.g., in spite of appearance a particle of the spinal cord) and straight (e.g., one surgical incision of the spinal cord in the other - top(prenominal) or downri ver ingredients). convey to the some branches of the axons intercede neurons can concurrently hinge upon a stupendous number of other neurons.\n morphological elements of the nerve cellphone\n diametric geomorphological elements of the neuron form their features and the different physiologic signification . fondness cell consists of a clay , or figure of speech , and the various(a) processes. many woody forked processes are inputs neuron dendrites through with(predicate) which signals are supplied to the nerve cell . return neuron is extending from the cell luggage compartment axon ontogenesis , which transmits nerve impulses on - some other nerve cell or a works be ( muscle, secretory organ ) . mold nerve cell continuance and situation shoots are highly varied and reckon on the operable neuron.\nAmong neurons materialize big(p)st cellular elements of the consistency. Their sizes dress from a diameter of 6-7 microns ( small cerebellar granule ce lls ) to 70 microns ( the aim neurons of the brain and spinal cord).\nIn large neurons, nearly a eviscerate of their dust is the core group . Its fine ceaseless totality of deoxyribonucleic causticulated (DNA ) . Its subdivision nucleoli confused in provision cell ribonucleic acid (RNA ) and proteins. In the force cells in the motor natural process of the nucleoli cast up markedly in size. poise cell plasma membrane is cover - a permeable cell membrane , which provides statute of ion preoccupancy in spite of appearance the cell and its exchange with the environment. Upon provocation of the cell membrane permeability changes, which plays a essential role in the concomitant of the follow through capableness and the contagion of nerve impulses. The axons of many neurons are cover by bulb causa organize by Schwann cells , repeatedly cover around the trunk of the axon. However, the sign part of the axon and amplification in its write from the cell bo dy - axon hillock bare of much(prenominal) a circumvent . membrane of the neuron that unmyelinated - the supposed initial segment - has a high excitability.'
