The non-pregnant and non-lactating female breast is composed primarily of adipose and collagenous tissue with mammary glands making up a very minor proportion of breast volume. The breast tissue is encircled by a thin layer of connective tissue called fascia. The breasts are found at the anterior thoracic wall anterior to the deep fascia and pectoral muscles.

As a woman ages especially once she reaches menopause the breast tissue contains more adipose fatty tissue. Clusters of alveoli make up lobules clusters of lobules make up the lobes and there are 12-20 lobes in each breast every woman is different. They consist of a series of ducts and secretory lobules 15-20.

Lobules are minuscule glands that produce milk. This tissue extends from the collarbone down to the underarm and across to the middle of the ribcage. The deep layer of this fascia sits immediately atop the pectoralis muscle and the superficial layer sits just under the skin.

And glandular tissue which affects the lactation functions of the breasts. Each lobe has its own duct. The breast has an inhomogeneous structure which is predominantly composed of adipose tissue and glandular tissue.

The female breast is mostly made up of a collection of fat cells called adipose tissue. Embedded in the breasts fatty and fibrous tissue are 15 to 20 glands called lobes each of which has many smaller lobules or sacs that produce milk. The characteristic bounce of the breast comes from the elasticity of the matrix of connective tissue fibers in the breast.

Female breasts have milk ducts and glandular tissue that aid breastfeeding. The skin covering the breast is similar to skin elsewhere on the body and has similar sweat glands hair follicles and other features. 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. There are blood vessels and lymphatic vessels in the breast. The breast or mammary gland consists of glandular tissue ducts fibrous tissue blood vessels lymphatic vessels and fat.

The medical name for breast is mammary gland. In women the breasts are composed principally of specialised tissue glandular tissue that produces milk. Blood vessels and lymphatic vessels a system of vessels that drains fluid are located throughout the breast.

These ducts converge at the nipple like spokes of a wheel. The mammary gland or breast tissue is the network of lobules and ducts surrounded by the fatty and fibrous connective tissues. The breast is the tissue overlying the chest pectoral muscles.

However the breast tissue is located on top of the muscles of the chest wall. In addition there are also suspensory Coopers ligaments and connective tissue such as collagen and elastin. Separated from them by the retromammary space.

Ducts are thin tubes that carry milk to the nipple. The mammary glands are modified sweat glands. The structure of the female breast is complex including fat glandular and connective tissue as well as lobes lobules ducts lymph nodes blood vessels and ligaments.

The breast is composed of mammary glands surrounded by a connective tissue stroma. Lobes Lobules And Milk Ducts. When the breasts are carefully examined significant asymmetries are revealed in most patients.

As a mammary gland the breast is composed of differing layers of tissue predominantly two types. Breast tissue is located on top of the muscles of the chest wall. Each lobule consists of many alveoli drained by a single lactiferous duct.

Lymphatic vessels pass through the stroma surrounding the lobules of the gland and convey lymph to collecting ducts. Subcutaneous fat and adipose tissue distributed around the lobules of the gland give the breast its smooth contour and in the nonlactating breast account for most of its mass.
