- Directions: Rearrange the statements based on how a menstrual cycle occurs by writing numbers 1-40 before the item. The process of fertilization may take place. A new egg cell starts to mature within the ovary The living of the uterus becomes thin after bieeding. The mature egA Uterine lining begin to break down and bleeding results An egg in the ovary continues to mature The endometrium or lining of the uterus become thicker in preparation for the Implantation of the fertilized egg. The mature egg is released. The mature egg moves to the surface of the aivary just before the mid-cycle. The next menstrual cycle is about to begin Directions Match the concepts about menstruation in column A. with the terms in column 8. write the letter of your answer. Column- A travels from the ovary to the uterus. 1. The hormone stimulates your ovarles to produce a round 5 to 20 smale sacs called follicies. 2. The first accurrence of menstruation 3. This occurs when fertilization does not take place. 4.…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._________________irections: Read each statement or question below carefully and fill in the blank(s) with the correct answer. 1 Refers to the series of changes that occur in sexually mature, non-pregnant formales which culminates into menses. 2. The secretos a hormone that stimulates the egg cells in the ovaries to grow 3. High level of progesterone produces .a hormone associated with anxiety and stress. _4. It is the abitity to become fertile or to produce an offspring _5. A system that consists the brain and the spinal cord. 6. It consists of 10 billion neurons that control everything a person does, such as thoughts, movernents, memory, and sense 10
- 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 2Part 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.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).
