apocrine gland


Definition of apocrine gland

: a gland and especially a sweat gland that secretes a viscous fluid into a hair follicle (as in the armpit or groin), is lined with a single layer of usually columnar cells, and typically does not become active until puberty

Note: It is now understood that apocrine glands produce a secretion which lacks cellular material and causes little damage to the secreting cell. While this secretion pattern is more closely related to the merocrine than the apocrine type, these glands continue to be referred to as apocrine glands because of their uniquely characteristic large secretory lumen and milky secretion.
