is stimulated from secretion by FSH from pituatry gland

Question 8

Answer 9

Question 10

do granulosa cells start to secrete fluid that creates cavities between cells?

Answer 10

yes

Question 11

granulosa cells that surrounds the oocyte is called

Answer 11

cumuls oophorus

Question 12

the inner layer of the cumuls oophorus that surrounds the oocyte is called?

Answer 12

corona radiata

Question 13

corona radiata is external to

Answer 13

zona pellucida

Question 14

what do theca cells produce ?

Answer 14

Produce hormones ( androgens ) which are transformed into estrogens by the granulosa cells

Answer 18

covered with vitelline membrane which is the cell membrane of the 2ry oocyte
the zona pellucida it is a coat of glycoprotein external to the vitelline membrane and separated from the vitelline membrane by the perivitelline space ( polar bodies )
corona radiata : follicular cells that suuround the 2ry oocyte at ovulation

Question 19

signs of ovulation:

Question 20

luteal phase

Answer 20

the ruptured follicle is transformed into corpus luteum which secrets mainly progesterone and a small amount of estrogen

Question 21

how do corpus luteum change to corpus albicans

Answer 21

if the 2ry oocyte is not fertilized the corpus luteum persists only 10-14 days then degenrates to form corpus albicans
