However Thus Would Lose As Regulation Body Much.

However thus would lose as regulation body much. For influence on the processes proceeding in a body, enough considerable quantity of hormones is necessary. Therefore should spend many forces for manufacture of hormones and according to them would remain for regulation less. Action hormones, in essence, represents continuation of nervous influence, and these hormones have on a hypophysis such regulating an effect. Absence at of some working functions allows it after a signal transmission on a hypophysis to be released for perception of the new signals arriving from external and private world. So, at first sight burdensome duplication of similar functions in and a hypophysis actually creates optimum conditions for regulation realisation. , thus, is the fourth level of regulation in an organism (sm, fig. 1). The fifth level of regulation - the central nervous system including and a cerebral cortex. Continuous changes of an environment demand the constant adaptation to them of body functions.
