BREAST AND LYMPHATIC Flashcards
paired mammary glands that lie over the muscles of
the anterior chest wall, anterior to the pectoralis major and serratus
anterior muscles
breasts
breasts
extend vertically from
second to the sixth rib
the breasts
extend vertically from the second to the sixth rib and horizontally
from (2)
sternum to the midaxillary line
female breast tissue enlarges in response to the hormones 2
estrogen
and progesterone
The upper
outer quadrant, which extends into the axillary area, is referred to
tail of Spence
Most breast tumors occur in this quadrant
TAIL OF SPENCE
These structures drain lymph from the breasts to filter out
microorganisms and return water and protein to the blood.
Lymph nodes
The nipple, which is located in the center of
the breast, contains the tiny openings of the ——- through which milk passes
lactiferous ducts
Areola size
1- to 2-cm radius
AREOLA CONTAINS WHAT TYPE OF GLAND? secrete a protective lipid
substance during lactation.
MONTGOMERY GALND/ SEBACEOUS GLAND
Female breasts consist of three types of tissue
glandular, fibrous,
and fatty (adipose)
constitutes the
functional part of the breast, allowing for milk production
Glandular tissue
WHAT TYPE OF ALVEOLI CELLS AND HOW MANY LOBES IN GLANDULAR TISSUE
ACINI CELLS AROUND 15-20 LOBES
converge into a single
lactiferous duct that leaves each lobe and conveys milk to the
nipple.
MAMMARY DUCTS
The slight enlargement in each duct before it reaches thenipple is called the —
lactiferous sinus
provides support for the glandular tissue
largely by way of bands called Cooper ligaments
FIBROUS TISSUE
The major axillary lymph nodes consist of 4
anterior (pectoral),
posterior (subscapular), lateral (brachial), and central (midaxillary)
nodes
