The female breasts, also known as the mammary glands, are located on the front of the body. They extend out of the chest wall between the abdomen and the neck. The ability to make breast milk allows women to provide nutrition and nourishment to their children through breastfeeding.
The breast is an organ whose structure reflects its special function: the production of milk for lactation breast feeding. The epithelial component of the tissue consists of lobuleswhere milk is made, which connect to ducts that lead out to the nipple. Most cancers of the breast arise from the cells which form the lobules and terminal ducts.
The breast is one of two prominences located on the upper ventral region of the torso of primates. In females, it serves as the mammary glandwhich produces and secretes milk to feed infants. At pubertyestrogensin conjunction with growth hormonecause breast development in female humans and to a much lesser extent in other primates.
What does the inside of the breast look like? This illustration shows the makeup of breast anatomy both inside and outside. This information will help you visualize what parts of the breast your doctor is referring to.
Each breast has 15 to 20 sections, or lobes, that surround the nipple in a radial manner, like spokes on a wheel. Inside these lobes are smaller sections, called lobules. At the end of each lobule are tiny "bulbs" that produce milk.
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring. Mammals get their name from the Latin word mamma"breast". The mammary glands are arranged in organs such as the breasts in primates for example, humans and chimpanzeesthe udder in ruminants for example, cows, goats, and deerand the dugs of other animals for example, dogs and cats.
Breasts are made up of fat and breast tissue, along with nerves, veins, arteries and connective tissue that helps hold everything in place. The main chest muscle the pectoralis muscle is found between the breast and the ribs in the chest wall. Image source: National Cancer Institute www. Breast tissue is a complex network of lobules small round sacs that produce milk and ducts canals that carry milk from the lobules to the nipple openings during breastfeeding in a pattern that looks like bunches of grapes.
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. A layer of fatty tissue surrounds the breast glands and extends throughout the breast.
As you learn about breast cancer, we will repeatedly reference the anatomy of the breast. Understanding the different parts and functions will help you better grasp the details of breast cancer. The female breast is mostly made up of a collection of fat cells called adipose tissue. This tissue extends from the collarbone down to the underarm and across to the middle of the ribcage.
