Lecture 37: Female Anatomy

Question 1

oocyte

Answer 1

immature egg

Question 2

follicular cells

Answer 2

surround oocyte

Question 3

ovarian medulla

Answer 3

where blood vessles are

Question 4

what differentiates first?

Answer 4

primordial follicles

Question 5

fertilization

Answer 5

in fallopian tube
should be in ampulla (probs other wise)
male and females cells merge

Question 6

transport

Answer 6

cillia

isthmus/falopian tube

Question 7

what collects ovum?

Answer 7

fimbria

due to chem attraction

Question 8

ovum and hormone production

Answer 8

in the ovary

ovaries produce ova

Question 9

where is selective barrier?

Answer 9

cervix

barrier from organisms and sperm

Question 10

sperm deposition

Answer 10

in vagina

Question 11

contraction

Answer 11

myometrium of uterus

Question 12

implantation

Answer 12

endometrium of uterus

Question 13

oogonia numbers

Answer 13

females are born iwth all they will ever have (cant make more)

born iwth 200,000-2 mill
40,000 at puberty
about 400 mature over womans life time

Question 14

oogonia

Answer 14

what germ cells become after migrating to ovary

they divide (mitosis)
most degenerate (atresia)

Question 15

SOME oogonia

Answer 15

become primary oocytes

then inactive till pubperty

Question 16

oogonia every month

Answer 16

hormone release causes sveral follicles to matuer

Question 17

2 things can happen to mature oogonia:

Answer 17

penetrated by sperm: fertilized

no prenetration: oogonia dies

Question 18

menses

Answer 18

degeneration and sloughing of endometrium functional zone (mensturation)

Question 19

proliferative phase

Answer 19

regrowth of endometrium in response to estrodial from follicles

Question 20

secretory phase

Answer 20

endometrial glands secrete mucous in response to progesterone and estrogen to prep for ovum

Question 21

if ovum doesnt attach to endometrium

Answer 21

layer sloughed away

Question 22

uterine cycle

Answer 22

menses
proliferative phase
secretory phase

Question 23

endometrium:

Answer 23

stratum functionalis

straum basalis

Question 24

endometrium: stratum functionalis

Answer 24

shed during menstration

Question 25

stratum basalis

Answer 25

replace strt funct. every month

Question 26

myometrium

Answer 26

3 layers smooth muscle

Question 27

perimetrium

Answer 27

viseceral peritoneum

Question 28

slide 6

Answer 28

6

Question 29

ovarian follicle

Answer 29

basic structural unit of ovary
developing follicle cointains one maturing oocyte (egg)

follicle is PRIMARY ENDOCRINE tissue in ovary during FIRST half of ovarian cycle- synths and secretes estradiol

Question 30

estradiol

Answer 30

most potent form of estrogens

Question 31

progression of ovarin follicle

Answer 31

primary oocyte in primordial follicle

antral follcile

mature follicle

Question 32

2 cells for estradiol production

Answer 32

theca cells

granulosa cells

Question 33

hromones for estradiol prodcution

Answer 33

LH

FSH

Question 34

Theca cell

Answer 34

cholesterol + LH–> progesterone–> androsterone

THEY CANT CONVERT ANDROSTENEDIONE TO ESTRADIOL

Question 35

Granulosa cell

Answer 35

Androstenedione-> testosterone + FSH and aromatase–> estradiol

CANNT CONVERT CHOLESTEROL TO ANDROSTENEDIONE

Question 36

where do oocytes mature

Answer 36

in developing ovarian follicles

Question 37

when does reproductive ability end

Answer 37

at menopause

Question 38

when does ability to release eggs start?

Answer 38

at ppuberty

release one at a time

Question 39

slides

Answer 39

11-19
