a Human eccrine glands live-stained in situ with neutral red. Arrowheads indicate the coiled portions of the eccrine glands. b Schematic illustration of a human eccrine gland. The human eccrine gland is an unbranched, coiled single-tubular exocrine gland (left). The coiled structure, which resides in the deep dermis, consists of the secretory duct (SD; green) and the excretory duct (ED; pink). The excretory duct starts within the coiled portion and then extends straight up to the skin surface. The wall of the excretory duct is composed of two layers of cuboidal luminal and basal cells (pink in upper right box). The wall of the secretory duct is composed of a monolayer of secretory luminal cells (orange in lower right box) and the surrounding monolayer of myoepithelial cells (green in lower right box).
