Flashcards in Female Reproduction Deck (42):
1

in the ovaries, the
cortex contains?
medulla?

cortex: ovarian follicles, not all in the same stage
medulla: blood vessels and nerves

2

stages of follicular development (6)

primordial follicle-> primary follicle-> secondary follicle-> graafian follicle->corpus luteum->corpus albican

3

uterine tube (3)

-fallopian tube
-thick layer of smooth ciliated muscle to help move oocyte
-has 3 regions (isthmus, ampulla, infundibulum)

4

ampulla

site of fertilization

5

fundus of the uterus

site of implantation

6

cervical canal

contains cervical glands that secrete mucus plug

7

layers of the uterine wall? (3)

-perimetrium
-myometrium
-endometrium

8

myometrium

contains smooth muscle which is required to expel the embryo

9

endometrium (3)

-undergoes cyclic changes in response to hormones
-contains gland to secrete uterine milk
-contains 2 layers

10

what are the two layers of the endometrium?

-stratum basale (bottom)
-stratum functionalis (regrown every month)

11

functions of the vagina (3)

-menstrual discharge
-receives semen during intercourse
-passageway for delivery

12

why is the vagina acidic

there is stored glycogen that is converted to lactic acid via resident bacteria

13

transudation of the vagina

vaginal lubrication due to sweating of the vaginal tissue engorged with blood

14

inside the vestibule is (4)

-urinary orifices
-vaginal orifices
-clitoris
-vestibule gland (Bartholin)

15

gnRH (2)

-triggers puberty
-stimulate the release of LH and FSH

16

what are the stages of puberty in female reproduction?

-thelarche
-pubarche
-menarche

17

thelarche (2)

first stage
-breast development
-induced by estrogen

18

pubarche (3)

second stage
-growth of pubic and axillary hair
-increased activity of sebaceous and apocrine glands
-induced by androgen

19

menarche (3)

third stage
-first menstrual period
-induced by estrogen and progesterone
-must have 17% body fat

20

____ stimulates gnRH secretion during menarche

leptin

21

climacteric=______

end of fertility
menopause

22

menopause

cessation of the menstrual cycle due to low sex hormones levels

23

what are the effects of drops in estrogen and progesterone? (4)

-mood change
-rise in cholesterol
-decline in bone mass
-shifting of hormones levels->hot flashes

24

female and male germ cells arise from tissue within the ____

yolk sac

25

oogonia divide by mitosis until the _______

fifth month

26

oogensis stops when?

enters meiosis, but stops in prophase I

27

primordial follicle

primary oocyte together with follicular cell

28

granulosa cells

secrete estrogen and progesterone

29

under the influence of ______, when does the primary oocyte complete meiosis I

LH

30

ovulation

when the egg is pushed out of the ovary

31

what are the 2 consecutive phases of the ovarian cycle?

-follicular phase
-luteal phase

32

when do estrogen levels drop

after ovulation and was the corpus albican forms

33

female sexual cycle consist of

ovarian cycle
menstrual cycle

34

what are the stages of the menstrual cycle? (4)

-proliferative phase
-secretory phase
-premenstrual phase
-menstrual phase

35

what are the 2 consecutive phases of the ovarian cycle?

-follicular phase
-luteal phase

36

when do estrogen levels drop

after ovulation and was the corpus albican forms

37

female sexual cycle consist of

ovarian cycle
menstrual cycle

38

what are the stages of the menstrual cycle? (4)

-proliferative phase
-secretory phase
-premenstrual phase
-menstrual phase

39

proliferative phase

period of rebuilding
-estrogen stimulates production of progesterone receptors

40

secretory phase (2)

-starts after ovulation
-high progesterone->high glycogen secretion

41

premenstrual phase (2)

-endometrial degeneration
-blood flow drops and tissue becomes necrotic

42

menstrual phase (2)

-discharge of endometrial tissue
-contains fibrinolysin
