prepares

time when secondary sex characteristics appear
puberty
time beginning shortly before cessation of menstruation and lasting until 1 y after final period

begins 1 y following cessation of menstruations

< 21 d cycle

> 35 d cycle
purpose of the ovarian cycle
to provide an ovum for fertilization
describe the ovarian cycle in 5 steps
- primordial follicles develop
- dominant follicle emerges
- ovulation occurs (egg released from dominant follicle)
- dominant follicle collapses into CL
- CL degenerates into corpus albicans
what are the 3 phases of the ovarian cycle
- follicular (1-13)
- ovulatory (14)
- luteal (15-28)
what is the purpose of the endometrial cycle
provide implantation site for fertilized ovum
describe the endometrial cycle in 4 steps
- cycle begins on first day of bleeding
- functional layer regrows
- spiral arteries and uterine glands enlarge (great for implantation time)
- spiral arteries constrict, endo shrinks (ischemia)
what are the 4 phases of the endometrial cycle
- menstrual (1-5)
- proliferative (6-14)
- secretory (15-26)
- premenstrual (27-28)
cyclical changes to the endo are controlled by __
ovaries
what causes the endometrium to grow to it’s maximal thickness and secrete mucous
presence of corpus luteum
what happens to the endo with the degeneration of the corpus luteum
endometrial ischemia
what is the purpose of the hormonal cycle
initiate and control the menstrual cycle
which hormones control the endometrium
estrogen and progesterone
describe the hormonal cycle in 3 steps
- developing follicles produce estrogen; thus functional endo regrows
- CL produces progesterone and estrogen; thus endo thickens
- corpus albicans does not produce hormones; thus endo ischemia and resultant shedding
what hormones control the ovaries
follicle stimulating hormone (FSH) and luteinizing hormone (LH)
where in the brain does the endocrine system produce the hormones that control the ovaries
anterior pituitary gland
describe the hormonal cycle in reference to LH and FSH
- increase in FSH causes follicles to develop
- surge in LH (and FSH) causes ovulation
- more LH leads to collapse of dominant follicle and formation of CL
- anterior pituitary gland stops producing LH and FSH so CL degenerates into corpus albicans
what would be the 3 ovulatory phases aligned to pituitary involvement
- FSH = preovulatory
- LH+FSH surge = ovulation
- LH = post ovulation
what hormones control the anterior pituitary gland?

CL

production
which ovarian structure produces mostly progesterone
CL
which ovarian structure produces mostly estrogen
dominant follicle
what happens in the anterior pituitary gland when there are peak levels of estrogen
simulates GnRH causing a surge in FSH and LH
which hormones temporarily decrease after ovulation
estrogen and progesterone
postovulatory, residual LH maintains which ovarian structure
CL
why does CL degenerate
insufficient LH because increase in est and prog
