The breast or mammary gland overlies the pectoralis major muscle and is contained in the superficial fascia (Figure 4.5). Identify the nipple and areola.
On female cadavers, make a parasagittal cut through the breast [parasagittal view]. Reflect the breast tissue and examine the cut surface of the breast. Identify the lactiferous ducts and lactiferous sinuses.The breast is supported by suspensory ligaments (of Cooper) which extend from
the skin to the deep fascia. These ligaments
separate lobules of fat that make up most of the mass of the non-lactating breast and
give the breast its smooth contour. The breast tissue is organized as strands or sheets that extend between the lobules of fat.
