Q

Which is NOT true about the hormone progesterone?
A. It causes the endometrial lining to thicken in readiness for implanting of a fertilized egg
B. It relaxes smooth muscle to allow the uterus to grow during pregnancy
C. It causes release of the egg at ovulation, then makes the corpus luteum
D. When the levels drop it causes the thick endometrium to be shed in menses

A

C. It causes release of the egg at ovulation, then makes the corpus luteum (that is the prostaglandin)

Q

During which phase of the endometrial cycle does the endometrium thicken and prepare for potential implantation?

A

Secretory phase

17
Q

Which hormone is crucial for the maturation of the egg follicle and prepares the uterus for implantation?

A

Estrogen

18
Q

How does the body temp change around the time of ovulation?

A

It drops before ovulation and rises by 1/2 degree after ovulation

19
Q

What does “Spinnbarkeit” sign indicate during menstrual cycle?

Thin clear and stretchy cervical mucus (egg whites)

20
Q

Where does fertilization typically occur?

A

Outer third of fallopian tube

21
Q

Which hormone is NOT produced by the placenta?

A

FSH (follicle stimulating hormone)

22
Q

What is menarche?

A

Female’s first period

23
Q

When is the follicular phase of the menstrual cycle?

A

BEFORE ovulation

24
Q

When is the luteal phase?

A

LATER, after ovulation

25
Q

Follicular phase hormones

A

GnRH, FSH, LH—> ovulation

26
Q

What hormone does the embryo release?

A

Human chorionic gonadotropin (HCG)

27
Q

What hormone does a pregnancy test test for?

A

HCG (Hyman chorionic gonadotropin)

28
Q

What hormone is present when a pregnancy test is positive?

A

HCG

29
Q

What is the hormone process for menstrual cycle?

A

Hypothalamus—> GnRH—> anterior pituitary—> FSH, LH—> ovarian follicles—> Estrogen—>follicle releases egg—> corpus luteum (collapsed ovarian follicle after egg released)—> estrogen and progesterone (keep lining thick and prevent cycle from restarting)—> embryo—> HCG
