Any of the milk-producing apocrine glands typically occurring in pairs in female mammals and consisting of lobes containing clusters of alveoli with a system of ducts to convey the milk to an external nipple or teat. [TFD][VHOG]
The detailed similarities of mammary glands in living monotremes, marsupials, and eutherians argue for a monophyletic origin of these glands, perhaps by the combination of parts of preexisting sebaceous and sweat glands.[well established][VHOG]
The mammary glands of humans are in the thoracid/breast region. In other mammals they may be located elsewhere on the mammary ridges.
The male Dayak fruit bat has lactating mammary glands
A mouse mammary gland contains a single duct or sinus, forming 5-10 secondary ducts
The FMA class represents an individule lobe. The nipple is not a part
The MA class represents a composite structure, including the nipple, fat, connective tissue, smooth muscle as parts
The BTO class represents the combination of nipple plus lobe
A specialized accessory gland of the skin of mammals that secretes milk. The gland is typically only developed in females, and regresses in males.
Originally this was classified as a female reproductive structure, as it was in the MP in 2011
