What is the first phase of the menstrual cycle?
Proliferation phase
9 Day
What is the second phase of the menstrual cycle?
Ovulatory phase
an event
What is the third stage of the menstrual cycle?

14 days
What is the fourth stage of the menstrual cycle?
Menstrual Phase
True or false:

What happens during the Proliferation phase?
5 things
- Begins with the end of menstruation
- Lasts 9 - 10 days
- Endometrium Develops (proliferates)
- Follicular stage
- Ovaries prepare for ovulation.
What is the (1)follicular stage?
10-20 ovarian follicles mature.
What happens during the (2)Ovulatory phase?
- A Graafian Follicle ruptures and releases a mature ovum. (the other ripening follicles degenerate and are reabsorbed)
- Occasionally 2 Ovum are released resulting in fraternal twins.
- Ovulation is set in motion when estrogen levels reach CRITICAL levels.
- Basal body temp usually dips slightly at ovulation and rises o.5 C upon the day of ovulation.
What happens during the (3) Secretory -luteal- phase
- lasts roughly 15 days
- Graafian follicle becomes Corpus Luteum
- Estrogen and progesterone levels peak around the 20 or 21 day of the cycle causing the glands in the endometrium to secrete nutrients that would sustain a fertilized ovum.
- If no fertilization occurs, then the corpus lutem decomposes and hormone levels fall

Estrogen
LH
