Q

what does the graffian follicle make to shut off FSH?

A

inhibin

20
Q

where is the primary oocyte in a graafian follicle?

A

off center on a small mound of granulosa cells

21
Q

what are the granulosa cells called that surround the zona pellucida in the graafian follicle?

A

corona radiata

22
Q

does the graafian follicle complete meiosis 1?

A

yes

23
Q

where is graafian follicle stopped in meiosis 2?

A

at metaphase

24
Q

what triggers the completion of meiosis 1?

A

LH surge

25
Q

what does the graafian follicle form after ovulation?

A

corpus luteum

26
Q

what are the two cells of the corpus lteum?

A

granulosa lutein cells

theca lutein cells

27
Q

what are atretic follicles?

A

degenerating follicles after graafian follicle is ovulated

28
Q

what are the three layers of the fallopian tubes?

A

mucose muscularis serosa

29
Q

what is special type of cells int eh mucosa layer of the tubes?

A

peg cells and ciliated cells

30
Q

what is the serosa made of in the tubes?

A

simple squamous epitheliem

31
Q

what is the role of the peg cells in the tubes?

A

secrete nutrients to nourish sperm and cytokines

32
Q

what are the three layers of the uterine wall

A

endo
myometrium
adevntitia

33
Q

what is epithelium of the endometrium?

A

simple columnar

34
Q

the stroma of the endometrium has a lot of what?

A

simple tubular glands

35
Q

what are the two layers of the endometriu,?

A

functional and basal

36
Q

what is the role of the functional layer of the endometrium?

A

thick superficial layer that ets sloughed off and is mainly responsive to hormonal changes

37
Q

what is the role of the basal layer of the endometrium?

A

deep layer tht is preserved during menstruation and has basal cells that remake the functional layer

38
Q

name the two artery types of the endometrium

A

coiled and straight

39
Q

where do coiled arteries go?

A

into both basal and functional layer

40
Q

where do straight arteries reside in endometrium?

A

only in basal layer

41
Q

what is the epithelium of the cervix?

A

mucus secreting simple columnar

42
Q

does the vagina have glands?

A

no..get mucus from cervix glands

43
Q

what are the three layers of vagina?

A

mucosa
muscularis
adevntitia

44
Q

what is special thing that is present in mucosa of vagina?

A

glycogen

45
Q

why is glycogen in mucosa of vagina?

A

used by bacteria to make lactic acid to lower pH during follicular phase of menstural cycle to inhibit pathogens
