The branch of juice of a pancreas is influenced by character of the accepted food. These influences are mediated through corresponding гастроинтестинальные hormones. So, the foodstuff strengthening secretion of hydrochloric acid in a stomach (экстрактивные substances of meat, vegetables, products of digestion of fibers), stimulate development секретина so, lead to allocation поджелудочного the juice rich with bicarbonates. Products of initial hydrolysis of fibers and fats stimulate secretion HTSK-PZ which, in turn, promotes allocation of juice with a considerable quantity of enzymes. Thus, at long prevalence in a diet only carbohydrates, either fibers, or fats there is also a respective alteration of fermental structure of pancreatic juice. The mechanism flavouring рецепции consists in the following. The flavouring substance split by a saliva to molecules, gets to a time of flavouring bulbs, enters interaction with гликокаликсом and is adsorbed on a cellular membrane of a microfiber, coming into contact with рецепторным fiber. It is supposed that in the field of a microfiber there are the stereospecific sites of a receptor perceiving only the molecules of substance. As a result there are деполяризация membranes and generation рецепторного potential. Formed in рецепторной to a cage медиатор (ацетилхолин, серотонин, etc.) In retseptorno-afferentnom синапсе leads to occurrence ВПСП, and then ПД which is transferred on fibres of a drum-type string - branches obverse (VII steam), языкоглоточного (IX steam) and верхнегортанного (X steam) craniocereberal nerves in an oblong brain, in a kernel солитарного a nerve in a kind паттерной to the nervous activity defining different flavouring sensations. From an oblong brain nervous fibres as a part of a medial loop go to вентральным to kernels of a visual hillock and further to a bark of the big hemispheres - латеральную a part of the postcentral crinkle and гиппокамп.
