what structure produces estrogen

Answer 66

Ovary

Question 67

what structure produces LH

Answer 67

pituitary

Question 68

Ovulation stimulation synopsis from FSH release

Answer 68

pituitary releases FSH ->increased FSH concentration in blood stimulates ovary follicles to create estrogen -> increased estrogen concentration causes pituitary to stop releasing FSH and release LH -> LH leads to ovulation

Question 69

Corpus Luteum is a temporary or permanent gland

Answer 69

temporary

Question 70

what becomes the Corpus Luteum

Answer 70

the vacated follice that egg departed from

Question 71

What hormone does Corpus Luteum release

Answer 71

progesterone

Question 72

menstruation cycle from egg release

Answer 72

egg released from follicle -> vacated follicle becomes Corpus Luteum -> Corpus Luteum releases progesterone -> progesterone stops pituitary and ovary glands hormone release for a period of time giving chance for fertilization of egg -> egg not fertilized -> Corpus Luteum disintegrates -> progesterone concentration decreases -> pituitary no longer inhibited by progesterone -> FSH released -> endometrium removed

Question 73

pregnancy commencement from egg release

Answer 73

egg released from follicle -> vacated follicle becomes Corpus Luteum -> Corpus Luteum releases progesterone -> progesterone stops pituitary and ovary glands hormone release for a period of time giving change for fertilization of egg -> pregnancy -> progesterone concentration stays high for pregnancy duration

Question 77

stated mechanism by which temporary contraception prevents conception

Answer 77

ovulation prevention (There are other mechanisms as well not stated in the slide. Such as changing the cervical mucous to limit sperm mobility. Also, it may thin the endometrium lining - which debatably prevents implantation during the instances where ovulation does occur and the egg is fertilized)
