apocrine sweat gland

Etymology: Gk, apo, from, krinein, to separate
one of the large dermal sudoriferous glands located in the axillary, anal, genital, and mammary areas of the body. Apocrine sweat glands open into the upper portion of a hair follicle instead of onto the skin's surface. Becoming functional only after puberty, they secrete perspiration containing nutrients consumed by skin bacteria. The bacterial waste products produce a characteristic odor. Compare eccrine gland.See also sudoriferous gland.

apocrine sweat gland

Any of the sweat glands in the axillae and pubic region that open into hair follicles rather than directly onto the surface of the skin as do eccrine sweat glands. They appear after puberty and are more developed in women than in men. The characteristic odor of perspiration is produced by the action of bacteria on the material secreted by the apocrine sweat glands.
