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 ciliogenesis in the

oviduct cells

during the normal ovualtion cycle, estrogen produces an increase in the secretion of ___ by anterior pituitary (adenohypophysis)

LH

what is the structure of the primordial follicle

primary oocytes that have acquired a single layer of flat surrounding 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

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 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

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 anterior pituitary (adenohypophysis)

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

increases mitosis of the tubular ducts

vaginal glycogen comes form ____ cells and is produces in response to ___

epithelial lining, estrogen

what is the source of sexually stimulated vaginal lube

transudate from vascular plexus deep in the epithelium of vagina

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

give the effects of estrogen on the mamary gland

mitosis of ducts

synthesis and secretion of milk is stimulated by

prolactin

in the ovarian follicle, FSH stimulates the ____ cell to form estrogen from androgens

granulosa

consider the formation of estrogen; role of LH

stimulates theca interna to make androgen from cholesterol

consider the formation of estrogen; role of FSH

stimulates granulosa to make estrogen from androgen

what hormone stimulates the secretory phase of endometrium

progesterone

What type of epithelium do early primary follicles have?

simple cuboidal

What are the stages of follicular development?

primordial follicle-->primary follicle-->multilayered primary follicle-->secondary follicle-->graafian follicle

What is the structure of the primordial follicle?

simple squamous layer of follicular cells

What do the follicular cells develop into?

granulosa cells

What do stromal cells develop into?

theca interna and theca externa

The primordial follicle has stromal cells, but no...

theca cells

What is the nature of theca externa cells?

connective tissue

What is the function of theca interna cells?

create and secrete ANDROSTENEDIONE (androgen)

What cells convert androgens to estradiol (estrogen)?

granulosa cells

When does zona pellucida formation begin?

in the primary follicle

What is the zona pellucida?

an amorphous substance secreted between the granulosa cells and the oocyte

How do cellular processes from oocyte contact granulosa cells through the zona?

gap junctions

What do granulosa cells secrete into the intercellular space of the follicle to create the secondary follicle?

liquor folliculi

What does the liquor folliculi contain?

secretory products:estrogen, progesterone, inhibin

What does the liquor folliculi become?

ANTRUM

What are the granulosa cells surrounding the secondary follicle called?

corona radiata

How is the corona radiata connected to the other side of the follicle?

cumulus oophorous

What happens to the cumulus oophorous just before ovulation?

it breaks down, allowing the oocyte to float freely within the antrum

The mature follicle has a fully developed....

ampulla

What happens at ovulation?

the follicle swells through the tunica albiguinea and germinal epithelium, and bursts releasing the egg into the pelvic cavity

When does the first meiotic division occur?

just before ovulation

When does the second meiotic division occur?

only if fertilization occurs, in the oviduct

What kept the oocyte from meiotically dividing before just before ovulation?

oocyte maturation inhibitor

What activated the oocyte to counteract effects of OMI and mature?

MPF

Before ovulation the granulosa cell produces...

estrogen

After ovulation the corpora lutea produces...

progesterone

What is the function of progesterone?

induces growth of the endometrial lining preparing for implantation

After ovulation, the follicle becomes....

corpora lutea

After ovulation the theca interna becomes...

theca lutea, still produces androgens and progesterone

After ovulation granulosa cells are called...

granulosa lutean cells, and continue to produce progesterone and convert androgens to estradiol

If pregnancy occurs, what happens to the corpora? If it does not?

1. corpora persists for up to 3 months 2. corpora becomes corpora albicans and degenerates

A surge in what hormone induces ovulation?

LH
