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, and deer , and the dugs of other animals for example, dogs and cats. Lactorrhea , the occasional production of milk by the glands, can occur in any mammal, but in most mammals, lactation , the production of enough milk for nursing , occurs only in phenotypic females who have gestated in recent months or years.

The Who, What, Where, When and Sometimes, Why.

The breast is an organ whose structure reflects its special function: the production of milk for lactation breast feeding. The epithelial component of the tissue consists of lobules , where milk is made, which connect to ducts that lead out to the nipple. Most cancers of the breast arise from the cells which form the lobules and terminal ducts. These lobules and ducts are spread throughout the background fibrous tissue and adipose tissue fat that make up the majority of the breast. The male breast structure is nearly identical to the female breast, except that the male breast tissue lacks the specialized lobules, since there is no physiologic need for milk production by males. Anatomically, the adult breast sits atop the pectoralis muscle the "pec" chest muscle , which is atop the ribcage.

The breasts are paired structures located on the anterior thoracic wall, in the pectoral region. They are present in both males and females, yet are more prominent in females following puberty. In females, the breasts contain the mammary glands — an accessory gland of the female reproductive system. The mammary glands are the key structures involved in lactation. In this article, we shall look at the anatomy of the breasts — their structure, innervation, vascular supply and any clinical relevance.

Breast tissue is a complex network of lobules small round sacs that produce milk and ducts canals that carry milk from the lobules to the nipple openings during breastfeeding in a pattern that looks like bunches of grapes. During puberty, hormones produced by the ovaries and pituitary gland a part of the brain that controls growth and other glands in the body cause the breasts to grow.
