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

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._________________
TOPIC: “Human Reproductive System” Explain how the female hormones GnRH, FSH, LH, and estrogen interact during the menstrual cycle to induce ovulation and, subsequently, the formation of the corpus luteum.
Create one comprehensive illustration of the ovarian and menstrual cycle. For the ovarian cycle, briefly describe each stage of oocyte development instead of drawing them. Make sure you present hormones that regulate this cycle. For the Menstrual cycle, it is important that you show the thickening of the endometrium.
Nursing During creating male contraceptives, what steps in fertilization might be possible to block to produce contraceptives in males.?
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
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)
menstrual cycle (put steps into week 1-4 categories )
Question:- Gonadotropin-releasing hormone (GRH) is a hormone from the hypothalamus responsible for the release of the tropic sexual hormones FSH and LH (whose peak induces ovulation) from the anterior pituitary that act on the ovary. Explain why it is advantageous to have the brain (rather than a typical negative feedback) control the dynamic secretion of GnRH over the 28-day period of the estrus cycle. Imagine when GnRH is produced.

Internal genitalia like the vagina, uterus, and ovaries in females, and the testes, epididymis, and vas deferens in males, originate from the Mullerian and the Wolffian ducts respectively. These two ducts are both present in the same fetus during the early phase of human development, but one will prevail over the other to make the developing conceptus a female or a male. If both persist, the baby will have an intersex condition. Discuss two syndromes that are examples of disorder of sex development (intersex condition), and how they will affect the future life of the newborn
