Lymphatics may also pass through tiny interval.

Anatomy of breast. Separated from them by the retromammary space. The breasts are found at the anterior thoracic wall anterior to the deep fascia and pectoral muscles. The breast is the tissue overlying the chest pectoral muscles.

Both the lobes and lobules are connected by milk ducts which act as stems or tubes to carry the milk to the nipple. The medical name for breast is mammary gland. The breast is somewhat circular in shape.

A tail of breast tissue called the axillary tail of Spence extend into the underarm area. Both females and males develop breasts from the same embryological tissues. In humans breast tissue begins to enlarge at puberty.

Breast shape varies among patients but knowing and understanding the anatomy of the breast ensures safe surgical planning see the image below. The mammary glands are modified apocrine sweat glands. Lymphatic vessels in the breast drain excess fluid.

Transversally from the lateral border of the sternum to the midaxillary line and vertically from the second through the sixth ribs. The breasts are paired structures located on the anterior thoracic wall in the pectoral region. In women the breasts are composed principally of specialised tissue glandular tissue that produces milk.

A sagittal cut-away view shows the structures that comprise the breast including the pectoralis major muscle fat. The amount of fat. Anatomy of the Female Breasts Parts of the Breast.

To some degree the breast also has a psychological function in that it is associated with sexuality. The mammary glands are made up of lobules milk-producing glandular structures and a system of ducts that transport milk to the nipple. Each breast consists of mammary glands and surrounding connective tissue.

The visible parts of breast anatomy include the nipples and areolae. The breast is one of two prominences located on the upper ventral region of the torso of primates. Anatomically the adult breast sits atop the pectoralis muscle the pec chest muscle which is atop the ribcage.

When the breasts are carefully examined significant asymmetries are revealed in most patients. Each breast consists of tissue overlying the chest wall muscles the pectoral muscles. Lymphatics in the breast parenchyma originate in the interlobular tissue and within the walls of the lactiferous ducts.

It mostly occurs at the base on the large breast muscle m. Serratus anterior and crossing the free edge. Each breast has the following boundaries.

The anatomy of the breast is quite simple and some of the different parts of the breast include the areola the nipple and fatty tissue. Each of these lobes is made up of many smaller lobules the gland that produces milk in nursing women. In females the breasts contain the mammary glands an accessory gland of the female reproductive system.

Mamma is a pair organ which relates to the type of the apocrine glands of the skin. Breast anatomy The breast is an endocrine gland placed on the front of the chest consisting of glandular acini also called alveoli coated by cells that have the property of securing milk under. The female breast has a role in both nourishing the offspring as well as offering immunological protection to the newborn baby.

The breast contains milk ducts that link the mammary glands and the nipple. Pectoralis major partially on the front of ridgeshaped muscle m. They are present in both males and females yet are more prominent in females following puberty.

Womens breasts are made of specialized tissue that produces milk glandular tissue as well as fatty tissue. The retro-mammary space is located between the posterior capsule of the breast and the fascia over pectoralis major. In females it serves as the mammary gland which produces and secretes milk to feed infants.

Breasts are part of the female and male sexual anatomy. The remaining part is made up of fatty tissue. The front area of the chest is known as the breast.

A variable degree of deep breast tissue particularly of the medial breast may collect into lymphatic vessels that perforate the deep fascia to drain into internal mammary nodes. Women generally have larger breasts than men. A healthy female breast is made up of 1220 sections called lobes.

The breast of an adult woman is a milk- producing tear-shaped gland. Gross Anatomy of the Normal Breast Definition. For females breasts are both functional for breastfeeding and sexual bringing pleasure.

The breast tissue extends horizontally side-to-side from the edge of the sternum the firm flat bone in the middle of the chest out to the midaxillary line the center of the axilla or underarm. Picture of the anatomy of the breast The breasts are medically known as the mammary glands. Positioned over the pectoral muscles of the chest wall and attached to the chest wall by fibrous strands called Coopers ligaments.

Breasts have a circular body and a nipple in the center surrounded by a pigmented area of skin called the areola. The breast consists of 1520 lobules of glandular tissue all individually drained by a corresponding lactiferous duct which empty at the nipple via the lactiferous sinus. The anatomy of the breast is depicted.

It is supported by and attached to the front of the chest wall on either side of the sternum by ligaments.
