Kalovye weights leave by means of the certificate дефекации, representing complex-reflex process опорожнения дистального department of a thick gut through back pass. At filling of an ampoule of a rectum калом and increase in it of pressure to 40 - 50 sm вод.ст. There is an irritation mehano - and барорецепторов. The impulses which have arisen thus on афферентным to fibres тазового (parasympathetic) and срамного (somatic) nerves go to the centre дефекации which is located in lumbar and крестцовой spinal cord parts (the involuntary centre дефекации). From a spinal cord on эфферентным to fibres тазового a nerve impulses go to internal сфинктеру, causing its relaxation, and simultaneously strengthen a rectum motility. The bodies which are carrying out secretory functions, are called as secretory, or экскреторными. To them carry kidneys, easy, a skin, a liver and a gastroenteric path. The main appointment of eliminative organs is a maintenance of a constancy of the internal environment of an organism. Ekskretornye bodies are functionally interconnected among themselves. Shift of a functional condition of one of these bodies changes activity of another. For example, at superfluous deducing of a liquid through a skin at high temperature the volume диуреза decreases. Infringement of processes of allocation inevitably conducts to occurrence of pathological shifts of a homeostasis up to destruction of an organism. Can i get high on wellbutrin The majority механорецепторов skin send impulses to a spinal cord on fibres of type And, and tickling receptors - on Svoloknam. Having passed through back backs in back columns, impulses are switched on интернейроны a spinal cord (the second нейрон, the first is in spinal ганглии) the same party. Further on ascending ways as a part of back columns they reach Gaulle's kernels and Burdaha which are in an oblong brain (the third нейрон). Then through a medial loop impulses arrive in вентробазальные kernels (specific) a visual hillock (the fourth нейрон) and further in the first and the second соматосенсорные zones of a bark of an opposite hemisphere (a back central crinkle).
