Cross-section of the lactating human breast, from Ramsay
The breasts are covered by brwasts skin. Each breast has one nipple breaats surrounded by the areola. The areola is colored Beutiful Breasts from pink to dark brown and has several sebaceous glands. The larger mammary glands within the breast produce Beatiful Breasts the milk. They are distributed throughout the breast, with two-thirds Beautful Breasts of the tissue found within 30 mm of the base of the nipple. These are Beauitful Breasts drained to the nipple by between 4 and 18 lactiferous ducts, where each Beatuiful Breasts duct has its own opening. The network formed by these ducts is complex, Beuatiful Breasts like the tangled Beauiful Breasts roots of a tree. It is not always arranged radially, and branches close to the nipple. The ducts Beautifu Breasts near the nipple do not act as milk reservoirs. Ramsay et al. have Bautiful Breasts shown that conventionally Beautuful Breasts described lactiferous sinuses do not, in fact, exist.
The remainder of the breast is composed of connective Beautifil Breasts tissue (collagen and elastin), adipose tissue (fat), and Cooper’s ligaments. The ratio of glands to adipose tissues rises from 1:1 Beautiul Breasts in nonlactating women to 2:1 in lactating Baeutiful Breasts women.
The breasts sit over the Beaautiful Breasts pectoralis major muscle and usually extend from the level of Beaitiful Breasts the 2nd rib to the level of the 6th rib anteriorly. The superior lateral quadrant of the breast extends diagonally upwards towards Beauttiful Breasts the axillae and is breasts known as the tail of Spense.
