Q

What hormones regulate the ovarian cycle?

A

GnRH, FSH, LH, estrogen, and progesterone.

17
Q

What is the ovarian cycle?

A

Monthly series of events associated with the maturation of an ovum.

18
Q

What are the phases of the ovarian cycle?

A

Follicular phase, ovulation, luteal phase.

19
Q

What happens during the follicular phase (days 1–13)?

A

Several follicles develop; one becomes dominant and matures.

20
Q

What triggers ovulation on day 14?

A

A surge in LH following high levels of estrogen.

21
Q

What is formed from the ruptured follicle after ovulation?

A

Corpus luteum.

22
Q

What does the corpus luteum secrete?

A

Progesterone and some estrogen.

23
Q

What happens during the luteal phase (days 15–28)?

A

Corpus luteum maintains endometrium; if no fertilization, it degenerates into corpus albicans.

24
Q

What is the menstrual cycle?

A

Changes in the endometrium in response to ovarian hormones.

25
What happens during the menstrual phase (days 1–5)?
Stratum functionalis is shed; bleeding occurs.
26
What happens during the proliferative phase (days 6–14)?
Endometrium rebuilds under influence of estrogen.
27
What happens during the secretory phase (days 15–28)?
Endometrium thickens and becomes vascularized to prepare for implantation.
28
What hormone dominates during the secretory phase?
Progesterone.
29
What causes menstruation to begin again?
Fall in progesterone when corpus luteum degenerates.
30
What is the role of FSH in the ovarian cycle?
Stimulates growth and maturation of ovarian follicles.
31
What is the role of LH in the ovarian cycle?
Triggers ovulation and formation of the corpus luteum.
