nipple

 [nip´'l]
1. the pigmented projection at the tip of each breast; it is smaller in men than women. In women it gives outlet to the lactiferous ducts. Called also mammary papilla, mammilla, and teat.
2. any structure shaped like the nipple of the breast; see papilla.

The nipples are located slightly to the side rather than in the middle of the breasts. Usually, the size of the nipple is in proportion to the size of the breast, but large nipples may be found on small breasts and vice versa.

Surrounding the nipple is a pigmented area called the areola. The color of the areola varies with the complexion. In childless women, it is usually reddish. During pregnancy it increases in size and darkens in color, becoming almost black in brunettes. The color fades after the milk-producing period ends. The tip of the female nipple contains tiny depressions that are openings of the lactiferous ducts. During pregnancy special care should be given the nipples. Any secretion that accumulates should be gently washed off. If the nipples are tender, the physician will advise the use of cold cream, cocoa butter, lanolin, or another emollient to increase their pliability.

nipple

Etymology: ME, neb, beak
a small cylindric, pigmented structure that projects just below the center of each breast. The tip of the nipple has about 20 tiny openings to the lactiferous ducts. The skin of the nipple is surrounded by the lighter pigmented skin of the areola. The depth of pigmentation of the nipple and areola in nulliparas varies from rosy pink to brown, depending on the complexion of the individual. In pregnancy the skin of the nipple darkens but loses some of its pigmentation when lactation is completed. Stimulation of the nipple in men and women causes the structure to become erect through the contraction of radiating smooth muscle bundles in the surrounding areola. In women the nipple enlarges somewhat and becomes more sensitive after puberty. Also called mammary papilla, papilla mammae, papilla mammaria.
