Reproductive Cells Summary

Question 1

kisspeptin neurons

Answer 1

location: hypothalamus
function: influence GnRH neurons

Question 2

GnRH Neurons

Answer 2

location: hypothalamus
function: secrete GnRH that targets gonadotropes in anterior pituitary

Question 3

gonadotropes

Answer 3

location: anterior pituitary
function: release LH and FSH that targets gonads

Question 4

LH

Answer 4

function: stimulates Leydig cells (male) and theca cells (female). Drives ovulation (female)

Question 5

FSH

Answer 5

function: stimulates sertoli cells (male) and granulosa cells (female). Stimulates follicle development (female)

Question 6

granulosa cells

Answer 6

location: follicle
function: secrete estrogen (endometrial proliferation), inhibin (inhibit FSH), AMH (inhibit follicle development), some progesterone

Question 7

theca cells

Answer 7

location: follicle
function: secrete androgens that go to granulosa cells

Question 8

luteal cells

Answer 8

location: corpus luteum
function: secrete progesterone (secretory phase), estrogen and inhibin

Question 9

sertoli cells

Answer 9

location: testes
function: Provide a variety of substances for spermatogenesis (growth factors, ABP, nutrients, etc.)

Question 10

Leydig cells

Answer 10

location: testes
function: Secrete androgens for spermatogenesis and secondary characteristics
