breasts another name
mammary glands
breasts considered accessories of
reproductive system
breasts are
specialized sebaceous glands .
breasts they are
conical and symmetrically placed on the sides of
the chest.
The greater pectoral and anterior serratus muscles underlie each breast.
Suspending the breasts are fibrous tissues, called
Cooper’s ligaments
Cooper’s ligaments which extend from the
deep fascia in the chest outward to just under the skin covering the breast.
The biologic function of the breasts is
-to provide nourishment
-protective maternal antibodies to infants through the lactation process
In the center of each mature breast is the
nipple
nipple
protrusion about 0.5 to 1.3 cm in diameter
The nipple is composed mainly of
erectile tissue,
nipple became
which becomes more rigid and prominent during the menstrual cycle, sexual excitement, pregnancy, and lactation.
The nipple is surrounded by the heavily pigmented
areola
Both the nipple and areola are roughened by small papillae called
tubercles of Montgomery
As an infant suckles, these tubercles secrete a ?
fatty substance that helps lubricate and protect the breasts.
The breasts are composed of
glandular, fibrous, and adipose tissue.
The glandular tissue consists of ?
which are arranged in a series of ?
separated from each other by?
A/acini, or alveoli
A/15 to 24 lobes
A/adipose and fibrous tissue.
Each lobe of breast is made up ?
Which made up of many?
They are lined with a ?
which secretes the ?
A/several lobules
A/grapelike clusters of alveoli around tiny ducts.
A/single layer of cuboidal epithelium,
A/various components of milk.
The ducts from several lobules combine to form ?
and then join to form the ?
A/larger lactiferous ducts
A/lactiferous sinuses
lactiferous sinuses, which serve as?
reservoirs for milk collection and open on the surface of the nipple.
The smooth muscle of the nipple causes?
erection of the nipple on contraction
The muscular pelvic floor of the bony pelvis is designed to?
It acts as a ?
thereby providing?
A/overcome the force of gravity exerted on the pelvic organs.
A/supporting structure to the irregularly shaped pelvic outlet,
A/stability and support for surrounding structures.
Deep fascia and the levator ani and coccygeal muscles form the part of the pelvic floor known as?
the pelvic diaphragm.
The components of the pelvic diaphragm function?
as a whole, yet they are able to move over one another
The levator ani muscle makes up the ?
major portion of the pelvic diaphragm.
