Picture of the anatomy of the breast The breasts are medically known as the mammary glands. The remaining part is made up of fatty tissue. The lymphatic vessels in the breast drain to the lymph nodes in the underarm area axilla and behind the breast bone sternum.

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. Drainage is via 1 group of parasternal nodes Ultimate drainage is via subclavian lymph trunk to vv. The mammary glands are made up of lobules milk-producing glandular structures and a system of ducts that transport milk to the nipple.

The breast anatomy of males and females is slightly different. In women the breasts are composed principally of specialised tissue glandular tissue that produces milk. The retro-mammary space is located between the posterior capsule of the breast and the fascia over pectoralis major.

Female breasts have milk ducts and glandular tissue that aid breastfeeding. Papilla mammae the pointy tip at the end of the breast. This glandular tissue or mammary glands are found in the subcutaneous tissue overlying the pectoralis major and minor muscles.

Male and female breast nipples have many nerves that enhance sexual arousal. The amount of fat. Anatomy of the breast.

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 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. Womens breasts are made of specialized tissue that produces milk glandular tissue as well as fatty tissue.

The breasts are the most prominent superficial structures in the anterior thoracic wall consisting of glandular tissue and a supporting fibrous and fatty matrix. Women are more prone to benign noncancerous breast disease. As a woman ages especially once she reaches menopause the breast tissue contains more adipose fatty tissue.

They are present in both males and females yet are more prominent in females following puberty. 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.

The breast of an adult woman is a milk- producing tear-shaped gland. The breasts are paired structures located on the anterior thoracic wall in the pectoral region. It is supported by and attached to the front of the chest wall on either side of the sternum by ligaments.

Anatomy of breasts on the outside is very simple. The breast does not contain muscles. They are structurally dynamic meaning that the anatomy changes depending on a womans age menstrual cycle phase and reproductive status.

In this article we shall discuss the anatomy of the breast its nerve supply blood supply lymphatic drainage along with various aspects of clinical significance. Women generally have larger breasts than men. When the breasts are carefully examined significant asymmetries are revealed in most patients.

Lymphatic vessels in the breast drain excess fluid. Lymphatics of the Breast Drain lymph from breast to series of nodes Lat. In females the breasts contain the mammary glands - an accessory gland of the female reproductive system.

All genders can get breast cancer. Drainage is via 5 groups of axillary nodes Supr. Breast shape varies among patients but knowing and understanding the anatomy of the breast ensures safe surgical planning see the image below.

Gross Anatomy of the Normal Breast Definition. Breast tissue is located on top of the muscles of the chest wall. In females it serves as the mammary gland which produces and secretes milk to feed infants.

Both females and males develop breasts from the same embryological tissues. This tissue extends from the collarbone down to the underarm and across to the middle of the ribcage. The female breast is mostly made up of a collection of fat cells called adipose tissue.

This is primarily because one of the main functions of the breast is to feed newborn infants. Anatomically the adult breast sits atop the pectoralis muscle the pec chest muscle which is atop the ribcage. The mammary glands are modified apocrine sweat glands.

The breasts are paired structures that lie in front of the anterior thoracic wall over the pectoralis major muscle. The medical name for breast is mammary gland.
