Flashcards in Lecture 5: Histology of the Female Reproductive System Deck (46)
What is the functionalis of endometrium?
Part of endometrium layer
-sloughed off during menstruation and replaced during each cycle
What is the basalis of endometrium?
Retained part of endometrium after menstruation and subsequently proliferates and provides a new epithelium and lamina propria
What are the 3 changes to the myometrium of the uterus during pregnancy?
3. Increase in collagen
What is proliferative endometrium?
Stroma proliferates and glands extend to surface
Correlated with ESTROGEN release from developing follicles
What is secretive endometrium?
Marked by ovulation and production of glycogen-rich secretion
Correlated with PROGESTERONE release
What are changes in endometrium?
Proliferative and secretive
What are the layers of the vagina?
-stratified squamous epithelium
-glycogen lamina propria
-loose connective tissue
2. Muscular layer
-longitudinal bundles of smooth muscle
-dense connective tissue rich in elastic fibers
Where does the mucus in vagina come from?
Comes from glands of uterine cervix
Vagina itself has NO GLANDS
What does the mammary gland look like at birth?
Short branching ducts with no alveoli
What does the mammary gland look like when nonpregnant?
Inactive duct system
What does mammary gland look like when during pregnancy
Alveoli proliferate at the ends of the ducts
Alveoli = spherical collections of epithelial cells that become active milk-secreting structures
What does mammary gland look like when lactating?
Milk secretion and accumulation in alveolar lumen
Plasma cell population increases around alveoli and is responsible for secretion of IgA
What produces the milk?
Produced by epithelial cells of the alveoli during lactation
What is milk made of?
1. lipid droplets 4% of milk
2. membrane-limited vacuoles
What is tamoxifen?
An antagonist of the estrogen receptor in breast tissue
