at ovulation, what happens to faciliatate sperm migration through the cervix
mucous is more acidic and more hydrated
edema of the endometrial and mammary stromas is caused by what
progesterone
in vaginal epithelium, the amount of glycogen and the rate of sloughin are dependant on estrogen--when would glycogen levels likely be highest and why is this important?
during ovulation, facilitation of sperm activity
during the normal ovualtion cycle, estrogen produces the ___ phase in the endometrium
proliferation
during the normal ovualtion cycle, estrogen produces ciliogenesis in the
oviduct cells
during the normal ovualtion cycle, estrogen produces an increase in the secretion of ___ by adenohypophysis
LH
the secondary oocyte is ovulate. how much DNA does it have
2N
what is the strucute of the primordial follicle
primary oocytes that have acquired a single layer of flat surrouding cells (granulosa)
the interstitial cells of the ovarian stroma secrete___. what is the likely product
estrogen, development of secondary sex characteristics at puberty
in the formation of estrogen in the ovary, ____ stimulates the ___cells to synthesize androgens from cholesterol
LH, theca interna
in menses, the ____ layer of endometrium sloughs off when concentration of ___ falls below critical levels
functional, progesterone
the ovarian hair cells secrete
androgen
how does the cervical mucous secreted at mid cycle differ from that secreted during the rest of the cycles
increased volume, more hydrated
from what tissue does the ovarian theca folliculi develop
theca interna
what hormone event stimulates the menstrual phase of the endometrium
decreased progesterone
in the ovarian hair follicule, FSH stimulates the ___cells to make estrogen from androgens
granulosa
which is true about the secretory phase of the endometrium
uterine glands become highly coiled, stroma becomes edematous, spiral arteries become highly coiled
what is part of the secondary ovarian follicle
granulosa
what is the significance of glycogen in the vaginal epithelium
make the environment more acidic for the sperm, to be released into the lumen when cells are sloughed off
the stroma of both the mammary glands and the endometrium become edematous in response to?
progesterone
why do leiomyomas regress after menopause
they are hormone dependant
consider the ovarian folicle, what hormone stimulates the granulosa cells in the follicular phase
FSH
consider the ovarian folicle, what do the granulosa cells do in response to FSH stimulation
make estrogen from androgens
in pregnancy, what hormone stimulates the secretion of progesterone by the corpus luteum
LH
what stimulates the LH surge
increased levels of estrogen for 36 hours
which portion of the endometrium is shed in menses
functional layer
in menses, the __ layer of the endometrium is not sloughed
basal
consider the post-pubescent female. give the effects of progesterone on the mammary gland
edema of the stroma, increase in stroma
consider the post-pubescent female. give the effects of estrogen on the adenoyhypophysis
increased LH, decreased FSH, move fimbrae closer to ovary
consider the post-pubescent female. give the effects of estrogen on the vaginal mucosa
increase glycogen, sloughing of epithelium
consider the post-pubescent female. give the effects of estrogen on the oviduct
ciliogenesis increase in secretion
consider the post-pubescent female. give the effects of progesterone on the endometrium
edema of stroma
consider the effects of estrogen. in the uterus it stimulates the ___ phase of endometrium
proliferation
consider the effects of estrogen. in the mammary gland it causes
increase mitosis of the tubular ducts
consider the effects of estrogen. in the adenohypophysis it causes
stimulates the LH and inhibits the FSH
vaginal glycogen comes form ____ cells and is produces in response to ___
epithelial lining, estrogen
the synthesis of the milk begins 1-2 days after delivery. why
increased estrogen and progesterone levels inhibit prolactin
what is the source of sexually stimulated vaginal lube
transudate from vascular plexus deep in the epithelium of vagina
ovarian hair cells secrete
androgens
what hormone stimulates the secretory phase of endometrium
progesterone
give the effects of estrogen on the oviduct epithelium
ciliogenesis increase in secretion
give the effects of estrogen on the vaginal epithelium
increase in glycogen production
