[The mechanism of the effect of the sympathetic nervous system on skin receptors].

It has been found that smooth muscles play an important role in the mechanism of a sympathetic nervous system effect on the activity of skin receptors. Greater activity of the sympathetic nerve fibres induces higher tension of smooth muscles and thus changes mechanical state of the tissues around the receptors. The latter condition, in its turn, affects the response of receptors to mechanical stimulation. A change in the smooth muscles tension in skin vessels affects the response of receptors to cooling of skin.
