Anatomy And Physiology Of Breast

Physiology of the breast. The anatomy and physiology of the breast the breasts comprise glandular connective and fatty tissue.

The Anatomy And Physiology Of The Breast

At the histo logical level the prepubertal breast both in males and in females consists of multiple rudimentary ducts arranged circum ferentially and converging towards the nipple.

Anatomy and physiology of breast. It is important for women to become familiar with the normal anatomy and physiology function of their breasts so that they can recognize early signs of possible abnormalities. This section outlines basic information on breast composition development and typical changes from puberty to pregnancy to menopause. At the blind end of each rudimentary duct are poorly developed but potentially secretory acini.

Physiology of the breast prior to puberty there are no discernible differences functional or structural between the male and female breast. The amount of fat. The breast is the tissue overlying the chest pectoral muscles.

At the blind end. Each of these lobes is made up of many smaller lobules the gland that produces milk in nursing women. The epithelial component of the tissue consists of lobules where milk is made which connect to ducts that lead out to the nipple.

Womens breasts are made of specialized tissue that produces milk glandular tissue as well as fatty tissue. The lobes are further divided into smaller lobules that produce milk for breast feeding. Small tubes ducts conduct the milk to a reservoir that lies just beneath your nipple.

At the histological level the prepubertal breast both in males and in females consists of multiple rudimentary ducts arranged circumferentially and converging towards the nipple. Specifically most breast cancer is thought to originate in the terminal ductal lobular unit tdlu. Within these tissues are milk producing cells.

Both the lobes and lobules are connected by milk ducts which act as stems or tubes to carry the milk to the nipple. Each breast contains 15 to 20 lobes of glandular tissue arranged like the petals of a daisy. Lobes lobules and milk ducts a healthy female breast is made up of 1220 sections called lobes.

The breast is composed of glandular ducts and lobules connective tissue and fat with most of the benign and malignant pathology arising in the duct and lobular network figure 2. Anatomy physiology of the breast the breast is an organ whose structure reflects its special function. The production of milk for lactation breast feeding.

Tiny openings in the nipple allow milk to flow.
