15
Q
purpose of the ovarian cycle
A
to provide an ovum for fertilization
16
Q
describe the ovarian cycle in 5 steps
A
- primordial follicles develop
- dominant follicle emerges
- ovulation occurs (egg released from dominant follicle)
- dominant follicle collapses into CL
- CL degenerates into corpus albicans
17

provide implantation site for fertilized ovum

20
Q
what are the 4 phases of the endometrial cycle

21
Q
cyclical changes to the endo are controlled by __
A

22
Q
what causes the endometrium to grow to it’s maximal thickness and secrete mucous

presence of corpus luteum
23
Q
what happens to the endo with the degeneration of the corpus luteum
A

24
Q
what is the purpose of the hormonal cycle
A
initiate and control the menstrual cycle
25
which hormones control the endometrium
estrogen and progesterone
26
describe the hormonal cycle in 3 steps
1. developing follicles produce estrogen; thus functional endo regrows
2. CL produces progesterone and estrogen; thus endo thickens
3. corpus albicans does not produce hormones; thus endo ischemia and resultant shedding
27
what hormones control the ovaries
follicle stimulating hormone (FSH) and luteinizing hormone (LH)
28
where in the brain does the endocrine system produce the hormones that control the ovaries
anterior pituitary gland
29
describe the hormonal cycle in reference to LH and FSH
1. increase in FSH causes follicles to develop
2. surge in LH (and FSH) causes ovulation
3. more LH leads to collapse of dominant follicle and formation of CL
4. anterior pituitary gland stops producing LH and FSH so CL degenerates into corpus albicans
30
what would be the 3 ovulatory phases aligned to pituitary involvement
1. FSH = preovulatory
2. LH+FSH surge = ovulation
3. LH = post ovulation
31

34
does the pituitary gland control the ovaries

35

36

37
what inhibits the hypothalamus

38

39
what hormone forms and maintains the CL

40

41

production
42
which ovarian structure produces mostly progesterone

43
which ovarian structure produces mostly estrogen
dominant follicle
44
what happens in the anterior pituitary gland when there are *peak* levels of estrogen
simulates GnRH causing a surge in FSH and LH
45
