A breast has many parts.[1]
1. Chest wall
2. Pectoralis muscles
3. Lobules
4. Nipple
5. Areola
6. Milk duct
7. Fatty tissue
8. Skin envelope.[2]

The breast is the upper ventral region of the torso of a primate, in left and right sides, which in a female contains the mammary gland that secretes milk used to feed infants.[3]

Each breast contains 15 to 20 lobes that are surrounded by subcutaneous adipose tissue. The breast size and shape comes from that tissue.[4]


Parts of the breast include the nipple, areola, mound, inframammary fold, and ducts. There are also various tissue types.

Inframammary foldEdit

The inframammary fold is the point on the body where the bottom root of the breast touches the chest wall. This spot is where the underwires in a bra should lay on.
