[Functional organization of the autonomic nervous system].

The relative role of the sympathetic and parasympathetic vegetative nervous system in the regulation of the visceral functions has been discussed. The modern data disproving the classical point of view of the antagonistic sympathetic and parasympathetic interaction are given. According to the idea of the polyfunctional parasympathetic regulatory apparently the parasympthetic innervation acts not only as inhibitory but also as acceleratory system. A special attention is paid to the intracardiac ganglionic-synaptic apparate carrying out the interaction between the central ad local regulatory influences. It is shown that the sympathetic activation appears mainly during stress situation and at some pathological states. Nevertheless, the sympathetic system can be also engaged in some actions which change some patterns of the cardiac parasympathetic regulation. The possibility of the sympathetic and parasympathetic interaction at the different regulatory levels is analysed: in the central nervous system, in the vegetative ganglia and in the effectory organs.
