Vagina
vagina is a ______________ sheath lined with a _________ __________

Back 2

fibromuscular

mucous membrane.

The wall of the vagina consists of three layers =

Front 4

Component cells are loaded with glycogen
As the surface cells desquamate, the glycogen is released and is fermented by

Back 4

Lactobacillus acidophilus

lactic acid
low pH
inhibits the growth of pathogenic bacteria

Front 5

no glands in the mucous membrane of the vagina. The epithelium is lubricated by mucus which originates from cervix.

Front 6

External Genitalia/ Vulva

They are composed of skin and a thin layer of

Back 6

smooth muscle.

Front 7

labia minora are folds of skin with a core of

Back 7

spongy CT
elastic fibers

stratified squamous
thin keratinized layer on the surface.
Sebaceous and sweat glands

Front 8

Vulva
clitoris is an =

erectile body

homologous of the corpora cavernosa of the penis.

Front 9

The clitoris is covered with a thin layer of =

Back 9

stratified squamous

specialized sensory nerve terminations as Meissner’s corpuscles, Pacinian corpuscles and Krause’s end bulbs.

Front 10

vestibule

is lined by a typical

Back 10

stratified squamous epithelium
numerous small glands
minor vestibular glands

+

Hint 10

major vestibular glands (glands of Bartholin), analogous to the bulbourethral glands
in the lateral walls of the vestibule.

Front 11

Mammary Glands

Back 11

specialized accessory glands of the skin

Each gland consists of
__-__ lobes

Hint 11

Front 12

Breast glands are what type of glands =

Back 12

compound tubuloalveolar type.

Front 13

Nipple and Areola:

Back 13

tall papillae
smooth muscle fibers.

Contraction of the muscle hardens and elevates the nipple.

Front 14

nipple is pigmented and contains special areolar glands (glands of ____________),

Back 14

Montgomery

which are large ________ glands of __________ type. Sweat and ________ glands and a number of coarse hairs are present also.

Hint 14

branched

apocrine

sebaceous

Front 15

At the tips of the smaller ducts (terminal interlobular ducts), the lobule is developed.

Back 15

A lobule consists of several intralobular ducts emptying into one terminal interlobular duct.

Hint 15

Each lobule is embedded in loose cellular intralobular connective tissue. Separating the lobules is a dense, less cellular interlobular connective tissue.

Front 16

nipple, the lactiferous ducts dilate to form the _________ __________

The lactiferous sinuses are lined by _______ ___________ epithelium at their external openings.

Back 17

stratified columnar or cuboidal epithelium.

Front 18

terminal interlobular ducts consists of _______ _______ epithelium

Back 18

simple cuboidal

resting on basal lamina and a discontinuous layer of
_______ ____________

Hint 18

myoepithelial cells.

Front 19

spherical droplets of various sizes containing lipids.
This is called

Back 19

apocrine secretion.

Front 20

milk proteins. Their synthesis occurs on ribosomes in the basal part of the cell. Lactose, synthesized from glucose and galactose also is a component of milk secreted by these cells. These are secreted by

Back 20

merocrine mode of secretion.

Front 21

The first secretion to appear after birth is called colostrum. It contains less fat and more protein than regular milk and is rich in =

Back 21

antibodies (IgA)

Front 22

The intralobular connective tissue surrounding the alveoli have some lymphocytes and plasma cells. These are responsible for the secretion of =

Back 22

Immunoglobulins.

Front 23

nursing action of child stimulates tactile receptors in the nipple, resulting in liberation of =

Back 23

oxytocin

Front 24

Postlactational Mammary Glands
With weaning most alveoli that developed during pregnancy undergo degeneration.

Back 24

Post-menopausal Mammary Glands:
reduction in size and atrophy of their secretory portions

Front 27

Benign breast diseases

Back 27

tissues of the mammary gland (connective tissue, ducts, and acini) can be the source of a pathologic condition.

Front 28

Fibrocystic changes

Back 28

most common of all benign
Hormonal imbalances are associated with fibrocystic changes. In this condition
proliferation of the connective tissue stroma and cystic formation of the ducts are observed.

Front 29

Fibroadenoma,

Back 29

second most common form of benign breast disease, occurs in young women (20 to 30 years old). Fibroadenomas are slow-growing masses of epithelial and connective tissues and are painless.

Front 30

Breast cancer

Back 30

80% of breast cancers originate in the epithelial lining of the lactiferous ducts. Epithelial cells lining the lactiferous ducts have estrogen receptors and about 50% to 85% of breast tumors
