title: [Organization of endogenous rhythms of motor functions].
abstract: Two categories of endogenous rhythmical activity of somatic and visceral musculature are considered: the basic rhythms determined by morphofunctional and age-related characteristics of an organ or system and the secondary rhythms characterized by wide spreading in different systems, age-related stability, and many-level organization. In early ontogenesis, both forms of rhythmical activity has he single goal - to provide homeostasis of the growing organism under conditions of limited external afferentation and imperfection of adaptive regulatory mechanisms. Formation of the secondary rhythms is considered as the way and the result of coordination of functions that have endogenous rhythmicity.
