Term
8 major events of menstrual cycle
Definition
1 anterior pituitary secretes FSH and LH
2 FSH stimulates follicles to multiply (one egg makes it to maturity)
3 follicles secrete estrogen which maintains sex characteristics and increase thickness of endometrium
4 high estrogen causes LH to be secreted and ovulation occurs
5 follicular cells form corpus luteum which secretes estrogen and progesterone which inhibits secretion of FSH and LH
6 no fertilization = corpus luteum degenerates and estrogen and progesterone levels drop
7 menstruation begins
8 FSH and LH are no longer inhibited and cycle begins
Term
