Secondary sexual characteristics

The nipple is a raised region of tissue on the surface of the breast from which, in lactating females, milk from the mammary gland leaves the body through the lactiferous ducts to nurse an infant. The milk can flow through the nipple passively, or it can be ejected by smooth muscle contractions that occur along with the ductal system. The nipple is surrounded by the areola, which is often a darker colour than the surrounding skin.

An udder is equivalent to the breast in primates and other mammals. The udder is a single mass hanging beneath the animal, consisting of pairs of mammary glands with protruding teats. In cattle, camels and deer, there are normally two pairs, in sheep and goats, there is one pair, and in some animals, there are many pairs. In animals with udders, the mammary glands develop on the milk line near the groin. Mammary glands that

Cellulite () or gynoid lipodystrophy (GLD) is the herniation of subcutaneous fat within fibrous connective tissue that manifests as skin dimpling and nodularity, often on the pelvic region (specifically the buttocks), lower limbs, and abdomen. Cellulite occurs in most postpubescent females. A review gives a prevalence of 85–98% of women of European descent, but it is considerably less common in women of East Asian descent. It is believed to be physiological rather than pathological. It can result from a complex combination of factors, including diet, sedentary lifestyle, hormonal balance, or h

Lactation describes the secretion of milk from the mammary glands in addition to the period of time that a parent lactates to feed her young. The process can occur with all sexually mature female mammals, although it may predate mammals. The process of feeding milk in all female creatures is called nursing, and in humans it is also called breastfeeding. Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk.
