Question 20

4 phases of the menstrual cycle?

Answer 20

1. Follicular phase-proliferative phase
2. Ovulation
3. Luteal phase- secretory phase
4. Menstruation

Question 21

The follicular phase of the menstrual cycle?

Answer 21

Just after menstruation, the egg matures in preparation for ovulation
-FSH is secreted to stimulate follicles in the ovaries
-One follicle begins to ripen and brings an egg to maturity
-Follicle secretes estrogen, stimulating growth of the endometrium

Question 22

Ovulation phase of menstrual cycle?

Answer 22

The follicle ruptures, releasing the mature egg
- Estrogen inhibits FSH production and stimulates the hypothalamus to produce GnRH, which causes the pituitary to begin the production of LH

Question 22

The luteal (secretory) phase of the menstrual cycle?

Answer 22

After releasing the egg, the follicle turns into a glandular mass of cells called the corpus luteum, which manufactures progesterone
- Corpus luteum continues to produce estrogen and progesterone for 10 to 12 days
-If pregnancy doesn’t occur, the hormone output declines sharply and the uterine lining is shed

Question 23

The menstruation phase of the menstrual cycle?

Answer 23

The endometrium of the uterus is shed off in the menstrual discharge

Question 24

What makes up the menstrual fluid?

Answer 24
