Question 6

What releases the steroid hormones

Answer 6

ovary

Question 7

function of GnRH

Answer 7

acts on anti. pit to release gonadotropins

Question 8

function of LH

Answer 8

act on ovary to increase estrogen/progersterone/inhibins

Question 9

functino of FSH

Answer 9

Act on ovary to increase estrogen/progesterone/inhibins.

Question 10

function of estrogen

Answer 10

Increases size of uterus, ovaries, vagina, breasts (does not convert them to milk producing organs). Proliferation of endometrial stroma lining. Inhibits osteoclast activity. Increases body protein and fat deposition. Sodium and water retention. Makes mucous thin and stringy which can help guide sperm

Question 11

function of progestone

Answer 11

Promotes secretory changes of uterus, prepares it for implantation. Decreases uterine contractions. Decreases prostaglandin production. Secretes fluid in fallopian tubes. Secretory development of breast tissue. Opposite effect on cervical mucous – increased viscosity.

Question 12

primary oocyte

Answer 12

surrounded by granulosa cells and is referred to as primordial follicle

Question 13

what do granulosa cells secrete

Answer 13

oocyte-maturation inhbiting factor that halts further maturation

Question 14

what are the 2 phases of follicular development

Answer 14

follicular phase

luteal phase

Question 15

follicular phase

Answer 15

endometrial proliferation

follicle development

Question 16

when does luteal phase occur

Answer 16

after oculation

Question 17

what happens during luteal phase

Answer 17

coreus luteum forms
endometrial differentation
menses

Question 18

level of INhibin A in follicular and luteal phase

Answer 18

low in follicular

high in luteal

Question 19

level of inhibin B in follicular and luteal phase

Answer 19

moderate in follicular phase

spikes at beginnin gof luteal, then is low

Question 20

level of estradiol in follicular and luteal phase

Answer 20

low in both but spikes inbetween

Question 21

LH and FSH levels in follicular and luteal phases

Answer 21

low in follicular

spikes at beginnin gof luteal then is low again

Question 22

what does LH cause in follicular phase

Answer 22

theca cells to synthesis androstendione

Question 23

what does androsternoid get converted to

Answer 23

estradiol

Question 24

what happens after the spike of FSH in follicular phase

Answer 24

granulosa and teca cells proliferate

Question 25

granulosa and theca cells proliferating leads to what

Answer 25

increased steroid production

Question 26

estradiola have what affect on RSH

Answer 26

increases FSH recepotors, increasing granulosa cell sensitivity to RSH and increasing follicular secretions

Question 27

effect of FSH and estradiol on LH

Answer 27

increases LH receptors on theca cells also increasing follicular secretion

Question 28

what affect does inhibin B have on FSH

Answer 28

inhibits

Question 29

proliferation of epithelial cells in endometrium is controlled by what, and when is this happening

Answer 29

estrogen | follicular phase

Question 30

what are progesteron and estrogen doing during the luteal phase

Answer 30

exert neg feedback at level of anti- pit.

Question 31

what happens with estrogen right before ovulation

Answer 31

spikes for a day, causes pos feedback on gonadotropins

Question 32

what is required for ovulation

Answer 32

LH

Question 33

what happens to progesterone if ovulation occurs

Answer 33

is thermogenic, increases basal body temp slightly

Question 34

what cells create the corpus luteum

Answer 34

thecal, granuloa, endothelial, lipids, and immune cells

Question 35

function of corpeus luteum

Answer 35

acts like a temporary endocrine gland that secrets estradiol and progestreone

Question 36

function of theca cells

Answer 36

convert cholesterole into androstedione in response to LH

Question 37

what happens to androstenedione

Answer 37

converted to estrdiol in luteinizing granuloa cells which are controlled by LH

Question 38

what is responsible for differention/secretory development of endometrial lining in luteal phase

Answer 38

progestone

Question 39

progestrone and inhibin A exert neg feedback on _______ from _____

Answer 39

gonadotropins | ant. pit

Question 40

less steroid synthisis from corpus luteum leads to what

Answer 40

regression of corpeus luteum

Question 41

decline in estrogen and progestrone resulines in what

Answer 41

release of proteolytic enzymes which lyse tissue

Question 42

corpus luteum secrets ____ which inhibits myometrial contractions

Answer 42

relaxin

Question 43

what affect does progesterone have during pregnancy

Answer 43

suppresses uterine contraction, inhibits prostaglandin produciton, impacts immune response

Question 44

what affect does estrogen have during pregnancy

Answer 44

stimulates uterine growth | thickens vaginal epithelium and growth/development of mammary epithelium

Question 45

what happens with GnRH during puberty

Answer 45

pulsatile release at night

Question 46

function of GnRH during puberty

Answer 46

increases estrogen synthesis

Question 47

decreass in folliicles during menopause results in what

Answer 47

decline in estradiol and inhiin

Question 48

what does decline of estradiol and inhibin result in

Answer 48

loss of neg feeddback and elevated LH, RSH.
