Reaction of cutaneous receptors to local, reflex, and general thermal influences
In studying the reaction of thermoreceptors the author used the method of investigating the functional mobility. It was shown by observations that during local heating or cooling of short duration there occurs a rapid and considerable demobilization of the receptor elements responding to both heat and cold at the site of application of the thermal stimuli. Evidently, in this case the thermoregulating processes of the organism are not disturbed and therefore the reaction is only local. With a prolonged action of To stimulation extended over a larger surface of the skin — a reflex reaction of the thermoreceptor system is observed which is manifested in the changed adjustment of cutaneous thermoceptors, not subjected to the effect of thermal stimulation. In this instance a differentiated reaction to heating and cooling is being noted: heating provokes demobilization, while cooling — mobilization of the thermoreceptors. With this temperature changes of outside or inside air a reciprocal relationship is observed between the reaction of cold and heat receptor systems of the skin.
The data obtained demonstrate that the cold receptor system reacts more rapidly and adequately to changes of external temperature while the heat receptor system responds more readily to the temperature changes in the body.
