The basic structure and the physiological function of human sweat glands were reviewed.
Histochemical and cytochemical techniques greatly contributed the elucidation of the ionic
mechanism of sweat secretion. X-ray microanalysis using freeze-dried cryosections clarified
the level of Na, K, and Cl in each secretory cell of the human sweat gland. Enzyme
cytochemistry, immunohistochemistry and autoradiography elucidated the localization of Na,
K-ATPase. These data supported the idea that human eccrine sweat is produced by the …
