Q

3 kinds of cells granulosa cells differentiate into in tertiary follicles (less important)

A

1) columnar corona radiata (adjacent to zona pellucida)
2) cumulus cells (surrounds corona)
3) membrana granulosa (lines follicular wall)

Q

corpus hemorrhagicum

A

precursor to CL after ovulation occurs.

  • fills with blood, capillaries invade
  • granulosa cells become granulosa lutein cells
  • theca interna cells become theca lutein cells
  • transition to endocrine gland which produces progesterone

Q

What happens to CL if pregnancy occurs?

A

enlarges then degrades to corpus albicans after parturition

22
Q

What happens to CL if pregnancy doesn’t occur?

A

degenerates and is invaded by connective tissue

23
Q

corpus atreticum

A

atretic follicle. Forms from follicles that fail to complete development.

  • oocyte liquifies
  • zona pellucida thickens and folds
  • invasion of connective tissue
  • luteinization of theca interna
24
Q

size of lumen in ampulla vs. isthmus

A

larger in ampulla

25
type of epithelium in ampulla
ciliated ep.
26
muscularis in ampulla vs. isthmus
thicker in isthmus
27
type of epithelium in isthmus
predominantly secretory cells, some ciliated epithelium.
28
type of uterus in marsupials
duples (two independent uteri)
29
tunica mucosa in uterus =
endometrium
30
tunica muscularis in uterus =
myometrium
31
tunica serosa in uterus =
perimetrium
32
Estrogen and progesterone high or low in estrous?
Estrogen high, progesterone low
33
Estrogen and progesterone high or low in metestrous/diestrous?
Estrogen low, progesterone high
34
In which stage of estrus cycle is glandular tissue in uterus the most prolific?
metestrous/diestrous
35
Estrogen and progesterone low or high in anestrous?
both low
36
In which stage of estrus cycle is glandular tissue in uterus LEAST prolific?
anestrous
37
nondeciduate placenta and species with it
- fetal trophoblast tissue interdigitates with maternal tissue but does not invade it - maternal tissue NOT lost at parturition - Ruminants, horses, sheep, pigs
38
Deciduate placenta
- Fetal tissue invades maternal tissue - Maternal tissue lost at parturition - Cats
39
cervix
valve-like entrance that safeguards the uterus; open during estrus and parturition
40
Type of epithelium in estrus vs. anestrus vagina?
estrus: cornified stratified squamous anestrus: non-cornified stratified squamous
41
Epithelium lining alveolar ducts in active mammary gland
simple cuboidal or columnar ep.
42
Merocrine secretions from mammary gland contain
protein, carbs
43
Apocrine secretions from mammary gland contains
lipids
44
Holocrine secretions from mammary gland contains
secretory cells, macrophages, leukocytes
