The breast is located in front of the chest,
one on each side of the midline. The nipple lies just below
the center of the breast.
The skin surrounding the base of the nipple
is darker than the complexion of the woman and is known as
the areola. The glands situated in this region lubricate the
nipple and areola during lactation and prevent them from
For better description, the breast is divided
into four quadrants by horizontal and vertical lines
crossing at the nipple. In addition a tail of breast tissue
frequently extends toward or into the armpit (axillary
TISSUE HAS THREE PRINCIPAL COMPONENTS
The Glandular tissue
is organized into 12 to 20 lobes, each of which
terminates in a duct that opens on the surface of the
nipple. Each milk-producing gland is drained by a small
duct, which in turn drains into the main duct that
receives milk from all other glands in that lobe. This
main duct opens on the surface of the nipple. In between
the lobes is present the fibrofatty tissue which gives
the breast itís characteristic contour.
The fibrous tissue,
supporting the glandular tissue, in form of suspensory
ligaments that connect both the skin and to fascia
underlying the breast.
is the predominant component and surrounds the breast.
The proportions of these
components vary with age, the general state of nutrition,
The male breast consists chiefly of a small
nipple and areola.
