Quantitation of the Output of Individual Sweat Glands and Their Response to Stimulation

Abstract
Simultaneous observation of the number of active sweat glands and of the quantity of sweat produced in a given skin area, makes it possible to calculate the avg. output of sweat per gland per unit period of time. Some variation in output of sweat glands on different parts of the human body is shown to exist. Excitation of the sweating mechanism by mild muscular exercise is marked chiefly by an increase in numbers of functional glands, with relatively small increase in output per gland. Upon more severe excitation, such as accompanies exposure to high environmental temps., an increased number of functional glands may be supplemented by an increased output per gland in a given period of time. The possible mechanisms by which these changes may be accomplished are discussed.
