On the basis of his own research and findings provided in the special literature the author puts to the critical analysis the present day concepts of the biological role of urotensin II, the caudal neurosecretory system hormone in animals and human organisms. The article shows the regulatory function of this hormone in animals and human organisms and its participation in psychosomatic and psychoendocrine disease pathogenesis, such as cardiovascular, sexual and reproductive systems, menstrual periods, adaptation and behavior. The key words:Urotensin II, physiological effects, cardiovascular, sexual and reproductive system diseases, stress, adaptation, ethology. 1. , . [ , 2. , . 8. ]/ . , . , B.C. , . .- , .
