diagrammatic presentation C Chegg fertilization positive LH FSH Influence of hormones on the ovarian cycle Complete the following statements to assess your understanding of the influence that hormones produced by the anterior p have on the ovarian cycle. Not all choices will be used. female reproductive system inhibits High levels of estrogen in the blood exert release of menstruation ovulation corpus luteum and to halt the follicular phase of t < GnRH 7 stimulates During the follicular stage, from the anterior pituitary stimulates the development of an ovarian follicle, which produces estrogen and a small amount of progesterone. negative feedback control over the anterior pituitary to stop the SafeSear uter

Briefly describe the role of BMP-4 in ovarian follicular development

Discuss the female menstrual cycle phases. Identify the hormones involved in this cycle and their role in each step.

Part 1 - Assignment Complete the following objectives: Define the menstrual cycle, ovarian cycle, and uterine cycle Organize the phases of the ovarian cycle (follicular & luteal) along side of the phases of the uterine cycle (menses, proliferative, & secretory) Include what is happening to the follicle and oocyte during each phase of the ovarian cycle Include what is happening to the uterus at each phase of the uterine cycle Include the hormones that are secreted at each phase, what they target, and the effects of each Include the days in the menstrual cycle when each phase occurs NOTE – Phases of the ovarian cycle overlap with phases of the uterine cycle. This is why you are asked to organize the cycles along side of one another Include what happens to hormone secretion if fertilization occurs, if implantation occurs, & if neither of them occur.

How can we answer these questions?

By postpartum day two, expected findings would include soft, nontender breasts fundal height 5 cm below the umbilicus moderate lochia rubra with egg-sized clots voids of at least 150 mL increased incidence of orthostatic hypotension Select all that apply.

There is a decrease of E2 at the and of the menstrual cycle. What cuses it? 1. negative feedback of E2 2. the corpus luteum degenerates 3. positive fedback of E2 the release of negative feedback of E2

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. Use the slideshow on this website as a resource, it's very informative Menstruation Secretory Phase Proliferative Phase Ovulation

D Question 13 Menstruation occurs when there is a decrease in levels of estrogen and progesterone. levels of FSH and LH. O endometrial thickness. the number of follicles. the number of sperm present.
