Position and function of the breasts - the female breasts (mamma) sit between the third and seventh rib on the large and small pectoral muscles. They consist of the milk-producing mammary gland (glandula mammaria), also called the mammary gland, and the areola with the nipple.
Structure of the female breasts
The mammary glands already develop in the embryonic stage, the female round bulge develops during puberty. This bulge consists of adipose and connective tissue and surrounds the mammary gland.
The gutter or gap between the breasts is the bosom. However, in common usage, the breast refers to the entire female breast area.
Primarily, the body develops breasts to nourish the newborn baby with breast milk produced by the mammary gland during pregnancy. Secondarily, the female breasts have a sexual function as an erogenous zone.
How does the mammary gland work?
The mammary gland (Glandula mammaria) is a solid, flattened, round body. It is composed of 15 - 20 glandular lobules (Lobuli), which are each connected via a milk channel with the nipple. The outputs of the milk channels are star-shaped on the nipple. When the mammary gland produces breast milk during pregnancy, the breast lobes pump the milk into the canals to the nipple.
The nipple (nipple) and the areola (areola) are significantly darker pigmented than the skin of the breast. The colors of the pigmentation range from pink to brown, depending on age and cultural descent. The nipple and areola are traversed by many small muscles and are sensitive to mechanical stimuli such as a child's mouth. The muscles contract, the nipple straightens and emerges clearly from the areola. This erection provides better milk flow and facilitates feeding to the infant.
Around the areola (areola) around sebaceous glands (Montgomerydrüsen) are arranged, the secretion moisturizes the sensitive skin area and keeps it supple, in order to avoid over-stimulation.
Can size and shape be influenced?
The genes are primarily responsible for the size and shape of the breasts. But the nutritional status of women, age and pregnancy also have an impact. The natural shape of the breast is the teardrop shape. It is also aimed at when building the breast using implants.
Aesthetics and eroticism - the sexual function of the breasts
The breasts are a symbol of femininity and fertility. In no other primate are the female breasts as pronounced as in humans. The nipple is one of the most sensitive erogenous zones in the female body. So the female breast has a double function: with the erotic attraction that emanates from it, it increases the desire for sex - and thus for reproduction - and it nourishes the baby. A firm, drop-shaped breast is particularly attractive. With the size of the breasts, the feeling of beauty varies according to personal preference.
There is still a stubborn belief that drooping breasts are a result of breastfeeding. That is not right.
The declining strength of the connective tissue is decisive for this. The weight of the breast, possible nicotine consumption, the age and the body mass index of the woman are mainly responsible for the change in breast shape. With a moderate, calorie-conscious diet and a healthy lifestyle, the connective tissue remains firm for a long time and the breasts in shape.
