The breast is the upper ventral region of the torso of a primate, in left and right sides, which in a female contains the mammary gland that secretes milk used to feed infants.

The Breast: cross-section scheme of the mammary gland.

They give the breast its offspring-feeding functions as a mammary gland.

The lymphatic drainage of the breasts is especially relevant to oncology, because breast cancer is a cancer common to the mammary gland, and cancer cells can metastasize ( break away ) from a tumour and be dispersed to other parts of the woman ’ s body by means of the lymphatic system.

The round shape of the breast helps to limit the loss of maternal body heat, because milk production depends upon a higher-temperature environment for the proper, milk-production function of the mammary gland tissues, the lactiferous ducts.

In men, the mammary glands are also present in the body, but normally remain undeveloped because of the hormone testosterone, however, when male lactation occurs, it is considered a pathological symptom of a disorder of the pituitary gland.

The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual.

On Dolly's name, Wilmut stated " Dolly is derived from a mammary gland cell and we couldn't think of a more impressive pair of glands than Dolly Parton's ".

A well-studied example of morphogenesis that involves ECM is mammary gland ductal branching.

The ectoderm forms the skin, nails, hair, cornea, lining of the internal and external ear, nose, sinuses, mouth, anus, teeth, pituitary gland, mammary glands, eyes, and all parts of the nervous system.

The breast: cross-section scheme of the mammary gland: 1.

Female goats and ewes have two teats, each with a single mammary gland, located between the hindlegs.

Cows have four teats, each with one mammary gland in the udder.

Eosinophils are also involved in many other biological processes, including postpubertal mammary gland development, oestrus cycling, allograft rejection and neoplasia.

The anterior pituitary secretes prolactin, which acts on the mammary gland, adrenocorticotrophic hormone ( ACTH ), which acts on the adrenal cortex to regulate the secretion of glucocorticoids, and growth hormone, which acts on bone, muscle, and the liver.

Breast reconstruction surgery, for example, can use this technique when the mammary gland was removed by surgery ( mastectomy ).

A mammary gland is an organ in female mammals that produces milk to feed young offspring.

A mammary gland is a specific type of apocrine gland specialized for manufacture of colostrum when giving birth.

The basic components of a mature mammary gland are the alveoli ( hollow cavities, a few millimetres large ) lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells.

All the milk-secreting tissue leading to a single lactiferous duct is called a " simple mammary gland "; a " complex mammary gland " is all the simple mammary glands serving one nipple.

The primary function of the breasts — as mammary glands — is the feeding and the nourishing of an infant child with breast milk during the maternal lactation period.

Humans normally have two complex mammary glands, one in each breast, and each complex mammary gland consists of 10 – 20 simple glands.

Almost all instances of breast cancer originate in the lobules or ducts of the mammary glands.

Mammatus, also known as mammatocumulus ( meaning " mammary cloud " or " breast cloud "), is a meteorological term applied to a cellular pattern of pouches hanging underneath the base of a cloud.

The American Dialect Society had a number of related terms for Word of the year nominations in 2004, including Janet moment ( unplanned bodily exposure at a public function ), boobgate ( scandal over Janet Jackson's exposed breast ), nipplegate ( Like boobgate, but used earlier in squawk over Jackson's possible nipple ring ) and wardrobe malfunction ( overexposure in a mammary way ).

An example of true apocrine glands are mammary glands, responsible for secreting breast milk.

The functional breast: a mammary gland in medias res, feeding an infant child.

Within the mammary gland, the lactiferous ducts produce breast milk, and are distributed throughout the breast, with two-thirds of the tissue within 30-mm of the base of the nipple.

Nonetheless, it is statistically rare for a young woman to experience virginal mammary hypertrophy that results in massive, oversized breasts, and recurrent breast hypertrophy.

At puberty, the breast grows in consequence to the influences of the hormones estrogen and progesterone ; as a mammary gland the breast is composed of lobules of glandular tissue, each of which is drained by a lactiferous duct that empties to the nipple.

The arterial blood supply of the breast has medial and lateral vascular components ; it is supplied with blood by the internal mammary artery ( from the medial aspect ), the lateral thoracic artery ( from the lateral aspect ), and the 3rd, 4th, 5th, 6th, and 7th intercostal perforating arteries.

As a mammary gland, the breast comprises lobules ( milk glands at each lobe-tip ) and the lactiferous ducts ( milk passages ), which widen to form an ampulla ( sac ) at the nipple.

The death rate of metastatic breast carcinoma in patients with mammary Paget's disease and underlying cancer is 61. 3 %, with a 10-year cumulative survival rate of 33 %.

As the infected mice develop mammary tumors in adulthood, MMTV has inspired the search for a human breast cancer virus.

* Rapid spread of mouse mammary tumor virus in cultured human breast cells

The extra-abdominal form is rare and desmoids of the breast may arise in the mammary gland or may occur as an extension of a lesion arising from the muscles of the chest wall.

Food products produced by animals include milk produced by mammary glands, which in many cultures is drunk or processed into dairy products ( cheese, butter, et cetera ).

It is currently unknown at what stage the synapsids acquired mammalian characteristics such as body hair and mammary glands, as the fossils only rarely provide direct evidence for soft tissues.

Milk is a white liquid produced by the mammary glands of mammals.

In the anatomy of mammals, a nipple, mammary papilla or teat is a small projection of skin containing the outlets for 15 – 20 lactiferous ducts arranged cylindrically around the tip.

The physiological purpose of nipples is to deliver milk to the infant, produced in the female mammary glands during lactation.

Typically, the left internal thoracic artery ( LITA ) ( previously referred to as left internal mammary artery or LIMA ) is grafted to the left anterior descending artery and a combination of other arteries and veins is used for other coronary arteries.

It is currently unknown at what stage the synapsids acquired mammalian characteristics such as body hair and mammary glands, as the fossils only rarely provide direct evidence for soft tissues.

The presence of more than two nipples is known as polythelia and the presence of more than two complex mammary glands as polymastia.
