Question 29

what contain immature eggs cells?

Answer 29

Graafian follicles

Question 30

what is luteinizing hormone and where is it released from?

Answer 30

is released from the pituitary gland which causes the eggs to be released into the fallopian the during ovulation

-a zygote which turned into a ball of cells that were divided and can implant itself on the uterine wall. it will then turn into an embryo and grow a placenta

Question 39

uterine wall is aka?

Answer 39

-endometrium -this is where the blastocyst implants itself

Question 40

where does FSH and LH come from?

Answer 40

-the hypothalamus secretes GnRH which then will tell the anterior pituitary gland to secrete LH and FSH

Question 41

In males, LH is released to produce? -testosterone and FSH stimulate?

Answer 41

-more testosterone by signaling the testes - testosterone and FSH stimulate the production of sperm cells

Question 42

in females, FSH signals the? which means? and causes?

Answer 42

-ovaries to produce more estrogen which means some eggs will mature in the ovary's follicles and causes the uterine wall to thicken

Question 43

Answer 43

be released because it is most responsive to the LH

Question 44

what is corpus luteum?

Answer 44
