ANATOMY – PHYSIOLOGY Menstrual Cycle LAB Purpose:______________________________________________________________________________ __________________________________________________________ Observation Questions 1. Between days 25 and 12 (not 12 to 25) of the menstrual cycle, what happens to the amount of FSH produced by the body of an average human female? ______________________________________________________________________________________ __________________________________________________________ 2. What happens to the follicle between days 25 and 12 of the menstrual cycle? ______________________________________________________________________________________ __________________________________________________________ 3. During which days of the menstrual cycle is the level of FSH at its lowest in the blood stream? ________________________________________________________________________ ______________________________________________________________________________________ __________________________________________________________ 4. About how long is the follicle phase of the menstrual cycle? ______________________________________________________________________________________ __________________________________________________________ 5. On which day of the menstrual cycle is the production of LH the greatest? ________________________________________________________________________ 6. What event occurs immediately after this increased production of LH? ________________________________________________________________________ ________________________________________________________________________ 7. What happens to the corpus luteum during days 15 thorugh 24 of the menstrual cycle? ________________________________________________________________________ ________________________________________________________________________ 8.a. During which days of the menstrual cycle is the production of LH the lowest? ________________________________________________________________________ 8.b. What is happening to the corpus luteum at this time? ________________________________________________________________________ ________________________________________________________________________ 9.a. What happens to the amount of estrogen produced by the body during days 6 to 12 of the menstrual cycle? ______________________________________________ 9.b. What is occurring to the uterus during this time? ________________________________________________________________________ ________________________________________________________________________
10.a. What happens to the amount of progesterone produced by the body during days 6 to 12 of the menstrual cycle? ________________________________________________________________________ ________________________________________________________________________ 10.b. What is occurring to the uterus during this time? ________________________________________________________________________ ________________________________________________________________________ 11.a During which days of the menstrual cycle are the levels of both estrogen and progesterone at their lowest?_____________________________________________ 12. What event is occurring at this time? _______________________________________ Analysis and conclusions 1. How is the name follicle stimulating hormone appropriate to its function? ________________________________________________________________________ ________________________________________________________________________ 2. How is the name luteinizing hormone appropriate for its function? ________________________________________________________________________ ________________________________________________________________________ 3. Based on your observations, do you think estrogen and progesterone both cause similar changes in the uterus? Explain your answer ________________________________________________________________________ ________________________________________________________________________ 4. What events occur during the follicle phase of the menstrual cycle? ________________________________________________________________________ ________________________________________________________________________ 5. What events occur during the luteal phase of the menstrual cycle? ________________________________________________________________________ ________________________________________________________________________ Critical thinking and Application 1. What are the events described in this investigation referred to as a cycle? ________________________________________________________________________ ________________________________________________________________________ 2. The word "menstrual" comes from the Latin word mensis, meaning "month". How is the name appropriate for this cycle of the human female reproductive system? ________________________________________________________________________ ________________________________________________________________________ 3. If a female did not produce sufficient quantities of FSH and LH, how would her ability to have children be affected? ________________________________________________________________________ ________________________________________________________________________ 4. What standards did you use in this lab? ______________________________________________________________________________________ __________________________________________________________
