What is the breast made of?

Answers:

Breasts

Breasts are part of the anatomy of both females and males. On the inside, a woman's breast is made up of give or take a few 15-25 milk-producing sacs call milk glands, which are connected to milk ducts that converge inside the nipple.
The remainder of the internal breast is composed of fatty tissue and fibrous connective tissues that bind the breast together and give it shape.

On the outside of the breast in that are nipples. Nipples, like adjectives other anatomical structures, vary within appearance from woman to woman. They may stick out prominently, they may have a flattened appearance, they may be set a bit deeper within the breast, or they can be inverted.

Each nipple is supplied with abundant nerve ending, which make it chiefly sensitive to touch. There are thin muscle fibers within nipples that enable them to become erect. The dark pigmented area around respectively nipple is called the areola (plural: areolae).

The size and color of the areolae rise and fall from woman to woman. This area can be see as an extension of the skin of the nipple onto the breast. It contains many bravery fibers and muscle fibers that help the nipple to stiffen and become erect.

Bumps contained by the Aerola Normal
It is quite middle-of-the-road to have small bumps within the areola. These bumps are oil-producing glands that secrete a lubricant to bring in breast feeding easier. During pregnancy, the areolae darken and remain at lowest somewhat darker after pregnancy.

Women's breasts own three levels of significance: they can nurture a baby; they can donate erotic pleasure; and they play a large cut in shaping a woman's self-image.

In response to sexual stimulation, a woman's breasts may put up with changes. Her nipples typically become erect during sexual excitement. As excitement proceeds, the areolae get going to swell, continuing to the point where the ahead of time nipple erection may look less pronounced. The vein in the breast regularly become more visible as a result of the increased blood flowing into them, and, in women who own not breast-fed, there may also be a small increase in breast size.

The breasts are modified sudoriferous (sweat) glands, producing milk.[1]

The breasts are covered by skin. Each breast has one nipple surrounded by the areola. The areola is colored from pink to dusk brown and has several sebaceous glands. The larger mammary glands inside the breast produce the milk. They are distributed throughout the breast, with two-thirds of the tissue found in 30 mm of the base of the nipple.[2] These are drained to the nipple by between 4 and 18 lactiferous ducts, where on earth each duct have its own opening. The meet people formed by these ducts is complex, like the dishevelled roots of a tree. It is not always arranged radially, and branches close to the nipple. The ducts effective the nipple do not act as milk reservoirs. Ramsay et al. hold shown that conventionally described lactiferous sinuses do not, in fact, exist.

The remainder of the breast is composed of connective tissue (collagen and elastin), adipose tissue (fat), and Cooper’s ligaments. The ratio of glands to adipose tissues rises from 1:1 in nonlactating women to 2:1 in lactating women.[2]

The breasts sit over the pectoralis chief muscle and usually extend from the level of the 2nd rib to the even of the 6th rib anteriorly. The superior lateral quadrant of the breast extends diagonally upwards towards the axillae and is known as the tail of Spense. A diaphanous layer of mammary tissue extends from the clavicle above to the seventh or eighth ribs below and from the midline to the brink of the latissimus dorsi posteriorly.

The arterial blood supply to the breasts is derived from the internal thoracic artery (formerly called the internal mammary artery), lateral thoracic artery, thoracoacromial artery, and posterior intercostal arteries. The venous drainage of the breast is basically to the axillary vein, but here is some drainage to the internal thoracic vein and the intercostal vein. Both sexes have a immense concentration of blood vessels and nerves within their nipples. The nipples of both females and males can become erect in response to sexual stimuli. [3]

The breast is innervated by the anterior and lateral cutaneous branches of the fourth through sixth intercostal nerves. The nipple is supplied by the T4 dermatome.

The primary anatomical support for the breasts is thought to be provided by the Cooper’s ligaments, next to additional support from the skin covering the breasts themselves, and it is this support which determines the shape of the breasts. The external shape or size of the breast is not predictive of its internal anatomy nor of its lactation potential. In a small fraction of women, the frontal milk sinuses (ampulla) in the breasts are not flush near the surrounding breast tissue, which causes the sinus nouns to visibly bulge outward.

Lymphatic drainage
About 75 percent of lymph from the breast travels to the ipsilateral axillary lymph nodes. The rest travels to parasternal nodes, to the other breast, or abdominal lymph nodes. The axillary nodes include the pectoral, subscapular, and humeral groups of lymph nodes. These drain to the central axillary lymph nodes, later to the apical axillary lymph nodes. The lymphatic drainage of the breasts is particularly relevant to oncology, since breast cancer is a adjectives cancer and cancer cells can break away from a tumour and spread to other parts of the body through the lymph system by metastasis

The breast is made up of cartilage. It's softer and more flexible then bone. Your ears and antenna are also made of cartilage.

tissue and fat- that's why the get smaller when you lose shipment, since your breats are made of fat, when you burn overweight, you're burning fat surrounded by your breasts as well, and it's vise versa too, they draw from bigger when you gain weight.

ps. they're not made of cartilage, that's wrong
