[Autonomic nervous system and resistance of cardiovascular functions in experimental acute emotional stress].
A relationship between the (metabolic) activity of the sympathetic ganglia, such as stellate and upper cervical ones, which innervate the heart and the changes in blood pressure was found in rabbits with varying resistance of cardiovascular functions to acute experimental emotional stress induced by electric irritation of the ventromedial nuclei of the hypothalamus and skin. The activity of the upper cervical and stellate ganglia was demonstrate to determine the resistance of cardiovascular functions in emotional stress. That of the sympathetic nervous system was primarily due to the changes in the function of central regulatory links, including the catecholaminergic system of the hypothalamus and the blue spot. In addition, there is a decisive role of the sensitivity of baroreceptor reflex in the formation of resistance of cardiovascular reactions.
