MECHANISM OF EFFECT OF SYMPATHETIC NERVOUS-SYSTEM ON SKIN RECEPTORS

While researching the mechanism underlying the effect of the sympathetic nervous system on the operation of skin receptors, we demonstrated that a tremendous role in this process is played by smooth muscles, whose condition also mediates the sympathetic effect on receptors. The increase in the activity of the sympathetic nerve fibers results in an increase in the tonus of the smooth muscles which in turn alters the mechanical condition of the tissues surrounding the receptors. It was established that the change in the tonus of the smooth muscles in the skin itself affects the reaction of the receptors that is evoked by mechanical stimulation. The change in the tonus of the smooth muscles of the vessels affects the response of receptors caused by cooling of the skin.
