31

What is the functionalis of endometrium?

Part of endometrium layer
-sloughed off during menstruation and replaced during each cycle

32

What is the basalis of endometrium?

Retained part of endometrium after menstruation and subsequently proliferates and provides a new epithelium and lamina propria

33

What are the 3 changes to the myometrium of the uterus during pregnancy?

1. Hyperplasia
2. Hypertrophy
3. Increase in collagen

34

What is proliferative endometrium?

Stroma proliferates and glands extend to surface
Correlated with ESTROGEN release from developing follicles

35

What is secretive endometrium?

Marked by ovulation and production of glycogen-rich secretion
Correlated with PROGESTERONE release

36

What are changes in endometrium?

Proliferative and secretive

37

What are the layers of the vagina?

1. Mucosa
-stratified squamous epithelium
-glycogen lamina propria
-loose connective tissue
2. Muscular layer
-longitudinal bundles of smooth muscle
3. Adventitia
-dense connective tissue rich in elastic fibers

38

Where does the mucus in vagina come from?

Comes from glands of uterine cervix
Vagina itself has NO GLANDS

39

What does the mammary gland look like at birth?

Short branching ducts with no alveoli

40

What does the mammary gland look like when nonpregnant?

Inactive duct system

41

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

42

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

43

What produces the milk?

Produced by epithelial cells of the alveoli during lactation

44

What is milk made of?

1. lipid droplets 4% of milk
2. membrane-limited vacuoles

45

What is tamoxifen?

An antagonist of the estrogen receptor in breast tissue

46

What is androstenedione?

Precursor to BOTH estrone (which estradiol and estrone)
AND
Testosterone
Converted by 17B-HSD
