Webcam breast milk

A number of Western cultures associate breasts with sexuality and tend to regard bare breasts in public as immodest or indecent.Breasts, especially the nipples, are an erogenous zone.During pregnancy, the breast responds to a complex interaction of hormones, including estrogens, progesterone, and prolactin, that mediate the completion of its development, namely lobuloalveolar maturation, in preparation of lactation and breastfeeding.Along with their major function in providing nutrition for infants, female breasts have social and sexual characteristics.A small-to-medium-sized breast weighs 500 grams (1.1 pounds) or less, and a large breast can weigh approximately 750 to 1,000 grams (1.7 to 2.2 pounds) or more.The tissue composition ratios of the breast also vary among women.Breasts have been featured in notable ancient and modern sculpture, art, and photography.

In women, the breasts overlay the pectoralis major muscles and usually extend from the level of the second rib to the level of the sixth rib in the front of the human rib cage; thus, the breasts cover much of the chest area and the chest walls.The size of the areola can vary widely among women.The areola contains modified sweat glands known as Montgomery's glands.The suspensory Cooper's ligaments are fibrous-tissue prolongations that radiate from the superficial fascia to the skin envelope.The female adult breast contains 14–18 irregular lactiferous lobes that converge at the nipple.Subcutaneous fat covers and envelops a network of ducts that converge on the nipple, and these tissues give the breast its size and shape.At the ends of the ducts are lobules, or clusters of alveoli, where milk is produced and stored in response to hormonal signals.The 2.0–4.5 mm milk ducts are immediately surrounded with dense connective tissue that support the glands.Milk exits the breast through the nipple, which is surrounded by a pigmented area of skin called the areola.Both females and males develop breasts from the same embryological tissues.At puberty, estrogens, in conjunction with growth hormone, cause breast development in females.
