Flashcards in Lec 8-6 - Reproduction Deck (29):
1

these are present until 6-7 weeks and are bipotential but atrophy without testosterone

wolffian ducts (male structures)

2

these grow unless they are suppressed by MIF

mullerian ducts (female structures)

3

these secrete MIF

sertoli cells

4

these secrete testosterone and are activated by LH

leydig cells

5

female development is due to a lack of blank

hormones

6

primordial germ cells do not enter meiosis in blank but they do enter meiosis in blank

females, males

7

during puberty, sex hormone levels are blank

low

8

during puberty, there is a night time pubertal blank surge

LH

9

in males, this causes genetalia, musculature, growth spurt, larynx

testosterone

10

in males, this causes sexual hair, sebaceous glands

dihydrotestosterone

11

in females, this causes genetalia, breasts, pubic hair, fat distribution

estrogen

12

sertoli cells are aka because they allow sperm development and are activated by FSH and high testosterone

nurse cells

13

maturation of sperm takes this long

70 days

14

primary follicle consists of an oocyte surrounded by blank and blank cells

granulosa, theca

15

granulosa cells are female equivalent to blank cells and respond to blank and produce blank

sertoli, fsh, estradiol

16

theca cells are female equivalent to blank cells and respond to blank and produce blank

leydig, LH, androgens

17

oocyte completes first meiotic division at time of blank and second division at blank

ovulation, fertilization

18

corpus luteum responds to blank and blank to produce blank and blank

fsh/LH, estradiol/progesterone

19

during implantation, a placenta is formed and secretes blank which maintains blank and blank production from corpus luteum

hCG, estrogen, progesterone

20

blank in placenta convert androgens to estrogens

aromatase

21

onset of labor is triggered by these in sheep but we dont know in humans

cortisol, increased estrogen/progesterone ratio

22

hormones in labor after the onset has already happened

prostaglandins, oxytocin, catecholamines

23

prolactin inhibits this after giving birth

menstrual cycle

24

estrogen is a blank antagonist

calcium

25

menopause has a loss of blank due to losing theca and gruanulosa cells

estrogen, progesterone

26

maternal anabolic phase (first half of pregnancy to start storing food for fetus) has blank sensitivity to insulin

increased

27

maternal catabolic phase has accelerated blank and blank sensitivity to insulin

starvation, decreased

28

placenta cranks out these hormones

progesterone, estrogen

29

blank is responsible for the let down reflex of milk

oxytocin
