Female Menstural Cycle (steps)

Question 1

Low levels of estrogen and progesterone trigger the hypothalamus to release GnRH

Answer 1

Menstrual

Question 2

GnRH causes the pituitary to release FSH

Answer 2

Menstrual

Question 3

FSH causes a follicle to mature develop in the ovary

Answer 3

Menstrual

Question 4

The developing follicle releases estrogen

Answer 4

Menstrual

Question 5

Rising estrogen levels cause the endometrium to thicken due to cell division

Answer 5

Follicular

Question 6

The rising estrogen levels suppress the release of FSH through negative feedback

Answer 6

Follicular

Question 7

High levels of estrogen cause a significant spike in LH to release by the APG

Answer 7

Follicular

Question 8

The spike in LH causes the follicle to rupture and release the mature ovum (ovulation Day 14)

Answer 8

Follicular

Question 9

The empty follicle becomes a corpus luteum under the influence of LH

Answer 9

Luteal

Question 10

The corpus luteum releases progesterone

Answer 10

Luteal

Question 11

Rising levels of progesterone cause the lining of the endometrium to become secretory and continue to thicken

Answer 11

Luteal

Question 12

Rising levels of progesterone and estrogen inhibit the release of GnRH

Answer 12

Luteal

Question 13

The drop in GnRH causes LH and FSH levels to drop

Answer 13

Premenstrual

Question 14

The inhibition of FSH and LH causes the corpus luteum to degrade

Answer 14

Premenstrual

Question 15

The degradation of the corpus luteum causes the release of estrogen and
progesterone to decrease

Answer 15

Premenstrual

Question 16

Low levels of estrogen and progesterone cause the endometrial ling to become unstable and slough off (oxytocin)

Answer 16

Premenstrual
