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 ...
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.

Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. [1] The duct portion may be branched (called compound) or unbranched (called simple). The glandular portion may be tubular or acinar, or may be a mix of the two (called tubuloacinar). If the glandular portion branches, then ...
These may be positive for alpha smooth muscle actin and can contract and expel the secretions of exocrine glands. They are found in the sweat glands, mammary glands, lacrimal glands, and salivary glands. Myoepithelial cells in these cases constitute the basal cell layer of an epithelium that harbors the epithelial progenitor.
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 breast milk. They give the breast its offspring-feeding functions as a mammary gland. They are distributed throughout the body of the breast.

The preputial glands of mice and rats are large modified sebaceous glands that produce pheromones used for territorial marking.
