Correct Answers
Hypothalamic Pit Cycle steps, Follicular phase steps Correct Answer-
Menses begins
1. low levels of estrogen and progesterone prompt hypothalamus to
release GnRH
2. GnRH stimulates ant pit to release FSH and LH, FSH develops
primary oocyte to secondary oocyte
3. Secondary oocyte has theca cells that produce androgens and
granulosa cells make estrogen from the androgen
4. Rising estrogen levels cause POSITIVE feedback which causes more
GnRH, LH, FSH to be released.
5. Surge in LH causes ovulation, mature egg released 24-26 hours later
luteal phase of ovarian cycle Correct Answer-LH predominates during
days 15-28, LH stimulates secretion of progesterone by the corpus
luteum
1. Corpus luteum produces estrogen and progesterone from LH to
maintain endometrial lining. peak function 8 days after ovulation to
allow fertilized egg to implant
2. rising levels of estrogen and progesterone cause negative feedback
loop and decrease GnRH, LH and FSH production.
3. LH levels fall and cause the corpus luteum to die , and estrogen and
progesterone levels fall
4. Endometrial lining is shed
5. Menses begins and starts the cycle over....
,Ovarian cycle phases Correct Answer-follicular phase, ovulation, luteal
phase
Menstrual Phase of Menstrual Cycle Correct Answer-*days 1-5
*time when endometrium is shed from uterus
proliferative phase of uterine cycle Correct Answer-refers to the
estrogen-induced thickening of the endometrium
days 6-14, until ovulation. Repair of endometrial lining and it becomes
mature and ready for implantation
secretory phase of menstrual cycle Correct Answer-*days 15-28
mature egg released d/t surge in LH, corpus luteum produces
progesterone to mature the endometrial lining
*endometrium prepares for implantation of embryo
*progesterone levels prompt development of endometrium
Ischemic phase menstrual cycle Correct Answer-corpus luteum dies d/t
decrease in LH from ant pit. Decrease in estrogen and progesterone
cause blood supply in endo to spasm >ischemia >blood supply is
blocked and endometrium necrosis occurs. Endometrium separates from
basal layer causing menstruation
main hormone during follicular phase Correct Answer-estrogen: from
FSH and LH that cause mature egg
, progesterone present but low amount
main hormone during ovulation Correct Answer-LH causes the follicle
to release mature egg
Main hormone for luteal phase Correct Answer-Progesterone produced
by corpus luteum to maintain endometrial lining
