A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
The preputial glands of mice and rats are large modified sebaceous glands that produce pheromones used for territorial marking. [5] These and the scent glands in the flanks of hamsters have a similar composition to human sebaceous glands, are androgen responsive, and have been used as a basis for study. [5]
Sweat glands are distributed all over the body except nipples and outer genitals. Although the nipples do have the mammary glands, these are known as modified sweat glands. Sebaceous glands are typically found in the opening shafts of hair. They are not on the palms of the hands or the soles of the feet.

The breast is an apocrine gland that produces the milk used to feed an infant. The nipple of the breast is surrounded by the areola (nipple-areola complex). The areola has many sebaceous glands, and the skin color varies from pink to dark brown. The basic units of the breast are the terminal duct lobular units (TDLUs), which produce the fatty ...
Areolar glands, especially during pregnancy and lactation, emit odors that reliably cause newborn babies to face the breast and locate the nipple. Cleaning the breast or otherwise masking these scents makes it harder for newborns to find the nipple, and to get an important first drink of immunoprotective colostrum .
The mammary glands of mammals are specialized to produce milk, a liquid used by newborns as their primary source of nutrition. The monotremes branched early from other mammals and do not have the teats seen in most mammals, but they do have mammary glands. The young lick the milk from a mammary patch on the mother's belly.
The number and positioning of mammary glands and teats varies widely among mammals. The protruding teats and accompanying glands can be located anywhere along the two milk lines . In general, most mammals develop mammary glands in pairs along these lines, with a number approximating the number of young typically birthed at a time.
