The breast is one of two prominences located on the upper ventral region of the torso of primates. In females, it serves as the mammary gland latin porn video tumblr, which produces and secretes milk to feed infants.

At pubertyestrogensin conjunction with growth latin porn video tumblrcause breast development in females. Subcutaneous fat covers and envelops a network of ducts that converge on the nippleand these tissues give the breast its size and shape. At the ends of the ducts are lobulesor clusters of alveoliwhere milk is produced and stored in response to hormonal signals. Along with their major function in providing nutrition for infants, female breasts have social and sexual characteristics.

Breasts have been featured in notable ancient and modern sculpture, art, and photography. They can figure prominently in a woman's perception of her body and sexual attractiveness. 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. A large number of colloquial terms for breasts are used in English, ranging from fairly polite terms to vulgar lesbos porn movies slang.

Some vulgar slang expressions may be considered to be derogatory or sexist to women. 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. At the front of the chest, the breast tissue can extend from the clavicle collarbone to the middle of the sternum breastbone. At the sides of the chest, the breast tissue can extend into the axilla armpitand can reach as far to the back as the latissimus dorsi musclelatin porn video tumblr, extending from latin porn video tumblr lower back to the humerus bone the longest bone of the upper arm.

As a mammary glandthe breast is composed of differing layers of tissuepredominantly two types: Morphologically the breast is tear-shaped. 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, latin porn video tumblr. Milk exits the breast through the nipple, which is surrounded by a pigmented area of skin called the areola.

The size of the latin porn video tumblr can vary widely among women. The areola contains modified sweat glands known as Montgomery's glands. These glands secrete oily fluid porn bark lubricate and protect the nipple during breastfeeding.

The dimensions and weight of the breast vary widely among women. The tissue composition ratios of the breast also vary among women. Some women's breasts have varying proportions of glandular tissue than of adipose or connective tissues. The fat-to-connective-tissue ratio determines the density or firmness of the breast, latin porn video tumblr. During a woman's life, her breasts change size, shape, and weight due to hormonal changes during pubertythe menstrual cyclepregnancy, breastfeeding, and menopause, latin porn video tumblr.

The breast is an apocrine gland that produces the milk used to feed an infant. The nipple of the breast is surrounded by the areola nipple-areola complex. The areola has many sebaceous glands, and the skin color varies from pink to dark brown.

The basic units of the breast are the terminal duct lobular units TDLUswhich produce the fatty breast milk. They give the breast its offspring-feeding functions as a mammary gland. They are distributed throughout the body of the breast.

The terminal lactiferous ducts drain the milk from TDLUs into 4—18 lactiferous ducts, which drain to the nipple. The milk-glands-to-fat ratio is 2: In addition to the milk glands, the breast is also composed of connective tissues collagenelastinwhite fat, and the suspensory Cooper's ligaments. Sensation in the breast is provided by the peripheral nervous system innervation by means of the front anterior and side lateral cutaneous branches of the fourth- fifth- and sixth intercostal nerves, latin porn video tumblr.

The T-4 nerve Thoracic spinal nerve 4which innervates the dermatomic areasupplies sensation to the nipple-areola complex. The axillary lymph nodes include the pectoral chestsubscapular under the scapulaand humeral humerus-bone latin porn video tumblr lymph-node groups, which drain to the central axillary lymph nodes and to the apical axillary lymph nodes.

The lymphatic drainage of the breasts is especially relevant to oncology because breast cancer is common to the mammary gland, and cancer cells can metastasize break away from a tumour and be dispersed to other parts of the body by means of the lymphatic system. The morphologic variations in the size, shape, volume, tissue density, latin porn video tumblr, pectoral locale, and spacing of the breasts determine their natural shape, appearance, and position on a woman's chest.

Breast size and other characteristics do not predict the fat-to-milk-gland ratio or the potential for the woman to nurse an infant. The size and the shape of the breasts are influenced by normal-life hormonal changes thelarche, menstruation, pregnancy, menopause and medical conditions e.

The suspensory ligaments sustain the breast from the clavicle collarbone and the clavico-pectoral fascia collarbone and chest by traversing and encompassing the fat and milk-gland tissues. The breast is positioned, affixed to, and supported upon the chest wall, while its shape is established and maintained by the skin envelope.

While it has been a common belief that breastfeeding causes breasts to sag, [17] researchers have found that a woman's breasts sag due to four key factors: The base of each breast is attached to the chest by the deep fascia over latin porn video tumblr pectoralis major muscles. The space between the breast and the pectoralis major muscle, called retromammary space latin porn video tumblr, gives mobility to the breast. The chest thoracic cavity progressively slopes outwards from the thoracic inlet atop the breastbone and above to the lowest ribs that support the breasts.

The inframammary fold, where the lower portion of the breast meets the chest, is an anatomic feature created by the adherence of the breast skin and the underlying connective tissues of the chest; the IMF is the lower-most extent latin porn video tumblr the anatomic breast. Normal breast tissue typically has a texture that feels nodular or granular, to an extent that varies considerably from woman to woman. The study The Evolution of the Human Breast proposed that the rounded shape big breast anal porn a woman's breast evolved to prevent the sucking infant offspring from suffocating while feeding at the teat; that is, because of the human infant's small jaw, which did not project from the face to reach the nipple, he or she might block the nostrils against the mother's breast if it were of a flatter form cf.

Theoretically, as the human jaw receded into the face, the woman's body compensated with round breasts. The breasts are principally composed of adipose, glandularand connective tissues. The morphological structure of the human breast is identical in males and females until latin porn video tumblr.

For pubescent girls in thelarche the breast-development stagethe female sex hormones principally estrogens in conjunction with growth hormone promote the sprouting, growth, and development of the breasts. During this time, the mammary glands grow in size and volume and begin resting on the chest. These development stages of secondary sex characteristics breasts, pubic hair, etc. During thelarche, the developing breasts are latin porn video tumblr of unequal size, and usually the left breast is slightly larger.

This condition of asymmetry is transitory and statistically normal in female physical and latin porn video tumblr development. Approximately bulldozer porn years after the onset of puberty a girl's first menstrual cycleestrogen and growth hormone stimulate the development and growth of the glandular fat and suspensory tissues that compose the breast.

This continues for approximately four years until the final shape of the breast size, volume, density is established at about the age of Mammoplasia breast enlargement in girls begins at puberty, unlike all other primates in which breasts enlarge only during lactation. During the menstrual cycle, the curvy pov porn are enlarged by premenstrual water retention and temporary growth.

The breasts reach full maturity only when a woman's first pregnancy occurs. The breasts become larger, the nipple-areola complex becomes larger and darker, latin porn video tumblr, the Montgomery's glands enlarge, and veins sometimes become more visible. Breast tenderness during pregnancy is common, especially during the first trimester. By mid-pregnancy, the breast is physiologically delia ts porn of lactation and some women can express colostruma form of breast milk.

Pregnancy causes elevated levels of the hormone prolactinwhich has a key role in the production of milk. However, milk production is blocked by the hormones progesterone and estrogen until after delivery, latin porn video tumblr, when progesterone and estrogen levels plummet. At menopause, breast atrophy occurs. The breasts can decrease in size when the levels of circulating estrogen decline. The adipose tissue and milk glands also begin to wither. The breasts can also become enlarged from adverse side effect s of combined oral contraceptive pills.

The size of the latin porn video tumblr can also increase and decrease in response to weight fluctuations. Physical changes to the breasts are often recorded in the stretch marks of the skin envelope; they can serve as historical indicators of the increments and the decrements of the size and latin porn video tumblr of a woman's breasts latin porn video tumblr the course of her gloves porn pics. The primary function of the breasts, as mammary glands, is the nourishing of an infant with breast milk.

Milk is produced in milk-secreting cells mobil anal porn the alveoli. When the breasts are stimulated by the suckling of her baby, the mother's brain secretes oxytocin. High levels of oxytocin trigger the contraction of muscle cells surrounding the alveoli, causing milk to flow along the ducts that connect the alveoli to the nipple.

Full-term newborns have an instinct and a need to suck on a nipple, latin porn video tumblr, and breastfed babies nurse for both nutrition and for comfort. The breast is susceptible to numerous benign and malignant conditions. The most frequent benign conditions are puerperal mastitis female porn tumblr, fibrocystic breast changes and mastalgia. Lactation unrelated to pregnancy is known as galactorrhea. It can be caused by certain drugs such as antipsychotic latin porn video tumblrlatin porn video tumblr, extreme physical stress, or endocrine disorders.

Lactation in newborns is caused by hormones from the mother that crossed into the baby's bloodstream during pregnancy. Breast cancer is the most common cause of cancer death among women [29] and it is one of the leading causes of death among women. Factors that appear to be implicated in decreasing the risk of breast cancer are regular breast examinations by health care professionals, regular mammogramsself-examination of breastshealthy latin porn video tumblr, and exercise to decrease excess latin porn video tumblr fat.

Both females and males develop breasts from the same embryological tissues. Normally, males produce lower levels of estrogens and higher levels of androgenslatin porn video tumblr, top 10 porn games for pc testosteronelatin porn video tumblr, which suppress the effects of estrogens in developing excessive breast tissue. In boys and men, abnormal breast development is manifested as gynecomastiathe consequence of a biochemical imbalance between the normal levels of estrogen and testosterone in the male body.

Plastic surgery can be performed to augment or reduce the size of breasts, or reconstruct the breast in cases of deformative disease, such as breast cancer. Breast augmentation surgery generally does not interfere with future ability to breastfeed. In Christian iconographysome works of art depict women with their breasts in their hands or on a platter, signifying that they died as a martyr by having their breasts severed; one example of this is Saint Agatha of Sicily.

Femen is a feminist activist group which uses topless protests as part of their campaigns against sex tourism [35] [36] religious institutions, [37] sexismhomophobia [38] and to "defend [women's] right to abortion". There is a long history of female breasts being used by comedians as a subject for comedy fodder e. In European pre-historic societies, latin porn video tumblr, sculptures of female figures with pronounced or highly exaggerated breasts were common.

A typical example is the so-called Venus of Willendorfone of many Paleolithic Venus figurines with ample hips and bosom.
