Analyze and discuss concepts of health, wellness, and disease utilizing knowledge of human anatomy & physiology.

The menstrual cycle is complex and highly coordinated involving many organ systems. The nervous system, circulatory system, endocrine system and the reproductive system work together to ensure that hormones are released at the appropriate time and in the right amount resulting in ovulation. This system is well controlled and if any one component is out of balance, a woman may experience infertility.

One way this cycle is controlled is through negative feedback inhibition.

1. First, describe negative feedback inhibition. Be sure to include the role of the receptor, central processing and the effector. Why is maintaining homeostasis important?

2. Next, describe what happens during the Follicular Phase of the Menstrual Cycle in each of the following areas of the body. Which hormones are released and how is their release controlled? Include the roles of GnRH, LH, FSH, estrogen, progesterone.

a. hypothalamus

b. anterior pituitary

c. ovaries

d. endometrium

3. What happens during ovulation? When, on average does ovulation take place? Is this true for every woman? When and where can fertilization take place?

4. Describe what happens during the Luteal Phase of the Menstrual Cycle in each of the following areas of the body. Which hormones are released and how is their release controlled? Include the roles of GnRH, LH, FSH, estrogen, and progesterone. Include how negative inhibition controls the levels of the hormones.

a. hypothalamus

b. anterior pituitary

c. ovaries

d. Endometrium

5. What happens to the endometrium of no fertilization takes place?

6. Many women experience polycystic ovarian syndrome (PCOS). For some women with PCOS, LH levels may be higher than normal. How may the menstrual cycle be impacted?
