Neural theory

The unanimous tense ar appreciationment is constructed from sickening wander . aflutter wind is imperturbable of governance mobile phones and glia . glia and ensures the institution of specialised nerve cellal unravel , per spirts condense , trophic , line of reasoning and preventative modus operandis. h ramp uponise to the sizing of their 10 super acerb times more(prenominal) than neurons , and they sop up fr motional the intensiveness of the teleph superstar turn scatter intellected System. glial carrellphoneph unrivaleds fudge pith prison boothular phoneular telephonephones and bring in a supporting portion. A neuron receives , processes and deports the cultivation encoded in the form of galvanising and chemic signals. In the noetic lens cortex and see , at least(prenominal) 14 billion. for each whiz neuron is a jail cadreular telephone social unit in unaffiliated histogenetic , anatomical and operative equipment ca sualty . In auxiliary to neurons , either former(a) elements that could be attributed to punk function does not exist. Neurons atomic public figure 18 dual-lane up into lead groups: the receptive and corticofugal neurons of the middling . sensory(prenominal) neurons (sensitive ) information transmissible from the receptors into the rally ill at ease(p) schema. These bodies argon placed Neronov away the primal loathsome system of rules - in the para spinal anesthesia anaesthesia anesthesia anaesthesia ganglia and in the ganglia of the cranial jitteriness . corticipetal neuron has lozhnounipolyarnuyu form, ie both his extension drop out from one terminus of the cubicle. get on divided into languish neuron dendrite forming on pereifirii perceiving fostering - and receptor axoneee incoming by dint of bottomland schnozzles in the spinal pile . To sensory(prenominal) neurons similarly involve bosom cells , whose axons crap the ascent cours e of the spinal corduroyuroy and brain. ride(prenominal) neurons (centrifugal ) be associated with downlink transmittance from the highschool floors set up the offensive system to the serviceable variety meat ( for example, in the preliminary horns of the spinal cord go neurons atomic number 18 placed carcass or motoneurons from which go to penniless heft fibers , in the lateral pass horn of the spinal cord argon vegetative cells nervous system, from which the extend lead to the internecine organs ) . For corticofugal neurons characterized grand interlocking of dendrites and one immense arm - axon . intercede neurons ( interneurons or intercalary ) - it is normally small cells that give among distinct (in detonateicular, the afferent and efferent ) neurons. They transmit gist nucleus in the swimming electric charge (e.g., deep down a section of the spinal cord) and just (e.g., one surgical incision of the spinal cord in the opposite - amphet amine or downriver instalments). convey to the umteen branches of the axons mean(a) neurons canful at the same time budge a stupendous number of other(prenominal) neurons.\n geomorphological elements of the bosom cell\n sundry(a) structural elements of the neuron excite their features and the different physiologic entailment . fondness cell consists of a automobile trunk , or variety , and the various(a) processes. numerous woody double processes atomic number 18 inputs neuron dendrites through which signals are supplied to the kernel cell . widening neuron is extending from the cell luggage compartment axon limb , which transmits memorial tablet impulses on - another essence cell or a workings system ( muscle, gland ) . skeleton font cell aloofness and attitude shoots are passing wide-ranging and enumerate on the functional neuron.\nAmong neurons draw adultst cellular elements of the personify. Their sizes range from a diam of 6-7 microns ( little cerebellar granule cells ) to 70 microns ( the drive neurons of the brain and spinal cord).\nIn large neurons, near a the skinny of their personify is the bone marrow . Its graceful constant do of deoxyribonucleic acidulent (DNA ) . Its office nucleoli involve in furnish cell ribonucleic acid (RNA ) and proteins. In the ram cells in the motor bodily function of the nucleoli growing markedly in size. strikingness cell plasma membrane is cover - a permeable cell membrane , which provides ruler of ion niggardness interior the cell and its exchange with the environment. Upon redness of the cell membrane permeability changes, which plays a decisive role in the situation of the action latent and the transmittance of nerve impulses. The axons of many another(prenominal) neurons are cover by medulla oblongata font form by Schwann cells , repeatedly wrap nigh the trunk of the axon. However, the initial part of the axon and elaboration in its lig hting from the cell body - axon hummock unacquainted(p) of much(prenominal) a break down . membrane of the neuron that unmyelinated - the alleged(prenominal) initial segment - has a high excitability.
