Modeling the Menstrual Cycle: The menstrual cycle takes an average of 28 days to complete and repeat. There are 4 phases: Day 1-5 Menstruation (period) Day 6-14 proliferation Day 11-13 Ovulation Day 15-28 Secretory phase Task: Create and annotate a model to show what is happening in the female body during the 4 phases of the menstrual cycle. This can be done digitally or on paper. If you chose to do this on paper, just make sure it gets to Ms. B. Things to include: Arrange the phases into a cycle Include changes in hormone levels in each phase (PSH, LH, Estrogen, Progesterone) Changes in the uterine lining What is happening to the egg (follicular, ovulation, luteal phase) It might help to start with arranging the phases into a cycle and then fill in details about what is happening at each phase.

Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
Put each of the following into the category it belongs with respect to the menstrual cycle. Time between menstruation and ovulation Corpus luteum develops Period of time when fertilization is most likely to occur Menses or menstrual bleeding occurs Endometrium produces secretions LH surge occurs Endometrium rapidly increases in cell number Days 1-5 of the cycle Mature (Graafian) follicle forms Days 6-13 Days 15-28 Discharge of blood and part of the endometrium Proliferative Phase Secretory Phase Menstrual Phase
Select all that help prepare the uterus for labor Unpregulation of oxytocin receptors Increasing calming effect from elevated estrogen level Atrophy of the myometrium Initiation of menstruation
Direction: Study the given series of events below. Arrange the sequence of the following events in chronological order by numbering each event from 1 to 5 according to the four phases of the menstrual cycle. Then, indicate on the space provided in which phase of the menstrual cycle does each event occur. Example answer: 3 Follicular Phase ___The body produces Human Chorionic Gonadotropin (HCG) if the mature egg is in order to maintain the thickness of the uterine lining for the fertilized to develop into an embryo. If not fertlized, the corpus luteum will be dissolved into the body and disappear and both hormone levels will fell. ______________________ ___The Mentrual cycle officially starts.______________ ___The pituitary gland releases Luteinizing Hormone as a result of rising levels of estrogen in order to stimulate the ovary to release a mature egg._________________
Objective: Describe the feedback mechanisms involved in regulating processes in the female reproductive system. Materials: • copy of unsequenced events in menstrual cycle. • Pencil and paper Procedure: 1. Study the numbered diagrams/pictures of unsequenced events in menstrual cycle below. SEE FIGURE 1 2. Use a separate paper and copy the table below as guide in arranging the events based on its correct sequence. Write the NUMBER ONLY of the diagrams/pictures based on its corresponding stages/ events. SEE FIGURE 2
FSH (Follicle Stimulating Hormone) E2 (Estrogen/Estradiol) LH (Luteinizing Hormone) PG (Progesterone) OVULATION! PERIOD 14 28 Hormone changes in an average cycle Observe the diagram above. This graph represents the hormone levels during an average menstrual cycle. Answer the following questions. What does the y-axis represent? 2. What does the x-axis represent? (the unit is in days) 3. Notice that each hormone is represented by a specific color. Make a prediction based on observations from the diagram. Which hormone do you think triggers a period (shedding of the lining of the uterus)? Justify your answer. HORMONE LEVELS III
Where are oocytes produced? Describe the menstrual cycle, mentioning the essential hormones and their functions (and where it comes from). Make sure to detail processes in both the ovary and the uterus. Trace the path of an oocyte to the outside of the body (assuming it does not encounter sperm).
Understanding the causes of infertility can be valuablein developing new birth control methods. Cite a type ofcontraceptive based on each of the following causes of infertility:(a) failure to ovulate due to a hormonal imbalance;(b) a large fibroid tumor that disturbs the uterine lining;(c) endometrial tissue blocking uterine tubes;(d) low sperm count (too few sperm per ejaculate).
Which of the following causes the bleeding (menstruation) during the menstrual cycle? Reduced release of oxytocin which causes the uterine muscles to relax Increased release of estrogen (estradiol) from the ovaries that simulates the uterine muscles to contract Reduced release of progesterone from the ovaries Increased release of progesterone leading to blood clots
Describe the 28-day uterine cycle in females, citing important timeframes/hormones/events in the cycle. Your response must include the difference between fertilization occurring and fertilization not occurring throughout this cycle and how that would effect the cycle's "completion" (What I mean by this is describe the entire cycle and how it would change if a zygote is successfully formed and implanted into the uterus resulting in pregnancy)
