SEARCH. Mammary glands are located inside the breasts of sexually mature female body. They are in actuality modified sweat glands which are in fact comprised of secretory mammary alveoli and the appropriate ducts. Mammory glands are considered to be part of the integumentary system rather than the reproductive system. Size and shape of the female breast are different for every human body and factors such as race, age, body fat, and pregnancy can make a large difference in these variations. The release of estrogen during puberty releases hormones that stimulate the growth of the breasts and the functions of the mammary glands. Functionally, the mammary glands produce milk; structurally, they are modified sweat glands. Mammary glands, which are located in the breast overlying the pectoralis major muscles, are present in both sexes, but usually are functional only in the female. Mammary gland function is regulated by hormones. At puberty, increasing levels of estrogen stimulate the development of glandular tissue in the female breast. Estrogen also causes the breast to increase in size through the accumulation of adipose tissue. A mammary gland is an organ in female mammals that produces milk to feed young offspring. Mammals get their name from the word mammary.. In humans, the mammary glands are situated in the breasts. In ruminants such as cows, goats, and deer, the mammary glands are contained in the udders. The mammary glands of mammals other than primates, such as dogs and cats, are sometimes called dugs. Humans normally have two complex mammary glands, one in each breast, and each complex mammary gland consists of 10–20 simple glands. The presence of more than two nipples is known as polythelia and the presence of more than two complex mammary glands as polymastia. The mammary glands located in the breast are responsible for producing milk for a suckling baby following childbirth. Each gland consists of a series of lobules, or glands that produce milk. They connect to ductal lobes, which connect to the lactiferous ducts. Mammary glands and ducts are also important in gauging the stage of a woman’s breast cancer. Staging depends on where the cancer is located and what areas are affected. 1  Ductal carcinoma refers to cancer in the milk ducts. 2  It is the most common form of Mammary gland. The mammary gland is a gland located in the breasts of females that is responsible for lactation, or the production of milk. Both males and females have glandular tissue within the breasts; however, in females the glandular tissue begins to develop after puberty in response to estrogen release. Mammary glands only produce milk after childbirth. During pregnancy, the hormones progesterone and prolactin are released. The progesterone interferes with prolactin, preventing the mammary glands from lactating. During this time, small amounts of a pre-milk substance called colostrum are produced. Spaying greatly reduces the chances of a female dog developing mammary cancer. In those females spayed prior to their first heat cycle, mammary cancer is very, very rare. The risk of malignant mammary tumors in dogs spayed prior to their first heat is 0.05%. It is 8% for dog spayed after one heat, and 26% in dogs spayed after their second heat. Save to mypetMD. Benign and malignant tumors of the mammary glands occur fairly frequently in unspayed female dogs, in fact they are the most common type of tumor in the group. Spaying can largely reduce the risk of developing this type of cancer, especially if the dog is spayed before it has an opportunity to go into heat. There are two main types of mammary gland breast tumors, each with several subtypes of tumor growth. The mammary glands' function is to produce milk to feed newborn puppies. They are located in two rows that extend from the chest to the lower abdominal area; the nipples indicate their location on the trunk of the body.
