mammary glands

Etymology: L, mamma, breast, glans, acorn
lactiferous glands within the breasts. Glandular tissue forms a radius of lobes containing alveoli, each lobe having a system of ducts for the passage of milk from the alveoli to the nipple. The central part of the breast is filled with glandular tissue. Also called breast, mamma. See also lactation.

mammary glands

Compound glands of the female breast that can secrete milk. They are made up of lobes and lobules bound together by areolar tissue. The main ducts number 15 to 20 and are known as lactiferous ducts, each one discharging through a separate orifice upon the surface of the nipple. The dilatations of the ducts form reservoirs for the milk during lactation. The pink, or dark-colored, skin around the nipple is called the areola.
