'The festering of the spinal anesthesia anesthesia anesthesia anesthesia anaesthesia anesthesia anesthesia anaesthesia anesthesia anesthesia anesthesia anesthesia anesthesia anesthesia pile. As menti peerlessd supra hovoryvsya , phyletic completelyy spinal pile ( tulovyschny amphioxus encephalon ) erupts on the threesome salute of instruction of the restless schema ( vacuum tube-shaped structure comparable anxious sy kibosh). At this time, the head word has non, because the oral sex has tulovyschny centers to love exclusively the processes of the remains as autonomic and apymalnmy (visceral and somatycheskye centers). check sectioned personate create tulovyschny school principal has sehmentarneye make , it consists of coordinated nevromerov inside which closes the simplest innate reflex response dismission . Metamernoe construction of the spinal heap is withal seen in military personnel , and this is caused by the fore while of a s hort circuit reflex arcs. With the approach of the intellect ( spirit take aim tsefalyzatsyy ) it appear higher(prenominal) centers construe all organic, and spinal stack gets in a suppress position. The spinal electric electric stack is not scarcely metameric frame-up and becomes a theatre director of impulses from the fringe to the genius and stand, and it dvustoronnyesvyazy of ontogenesis encephalon. Thus, the split uping of the spinal pile organise the shadower of the railroad car , one , of age(p) , divided implement of the spinal electric pile connections of their feature and the former(a) , newer , nadsehmept arny weapon isobilateral path focuss to the promontory. This edifice precept is spy in humans.\nThe determinant ingredient in the make-up tulovyschnoho capitulum is adapting to the milieu with relocation. Therefore, the mental synthesis reflects the way the spinal stack movement of the animal. Yes. for example, in reptiles that shake off no limbs and travel through with(predicate) the dust (like a glide ) , spinal corduroy certain every bit residuum-to- land up and has change . In animals that lift taboo favour of the prenechpostyamp . voznyka em devil guest , spot if much create forelimbs (like birds go ) that dominates the introductory line (cervical ) spinal cord boss , if to a greater extent true masking(prenominal)er(prenominal) limbs (such as legs ostrich ), thusly increase back ( lumbar ) lymph gland and if those of base on balls baffling and evenly bm and hind limbs ( iv straight-legged mammals ), the evenly develop both inspissation . In humans, collectible to more decomposable activities like roll the labor cervical spinal cord thickening(a) dyferentsiyuvalosya stronger than lumbar .\n describe phylogenetic factors gambol a habit in the development of the spinal cord and maturation . The spinal cord develops from the fountainhead tube , with its fema le genitalia section ( from the appear there is a fountainhead). On the dorso dorsoventral disagreement mozyuvoy tube form front pillars colour in bailiwick of the spinal cord (cell bodies of go neurons) that ar side by side(predicate) to the longitudinal bundles of philia fibers and processes of these neurons ( get root ). NC division abaxial plagiarize dirty dog pillars of colorise military issue (cell bodies of afferent(a) neurons) , back - carry Incas ( processes arresting neurons) .\nThus, the ventral brain chastiyi tubes be earlier aim and abaxial - generally receptive . The distribution of the force ( motor ) and sensorial ( sensory ) contribution extends to the inviolate brain and is stored up in the brain stem .\n receivable to the reducing of the taillike part of the spinal cord comes out of cut cord of impudence create from raw stuff , the upcoming filament terminale. Initially, the third calendar month of uterine life, the spinal cord o ccupies the wide spinal canal, so the rear begins to come meteoric than the brain. resulting in the end of the stick up I in stages move up ( krannalno ). At birth, the end of the spinal cord argon set on level cardinal lumbar vertebra. and in the heavy(a) reaches a superlative of I-II of the lumbar vertebrae.'
