The Menstrual Cycle Place the events in the menstrual cycle in order starting with menstruation. 1. Secretion of FSH starts 2. A burst of LH is released 3. Follicles produce estrogen 4. Uterine lining is shed 5. Follicles develop inside the ovaries 6. Endometrium prepared for possible pregnancy 7. Corpus luteum produces progesterone 8. Ovulation occurs

During the follicular phase of the menstrual cycle, a number of events occur which are listed below. Select the answer that places the events in the correct chronological order. Events: 1. the lining of the uterus starts thickening 2. granulosa cells secrete estrrogens 3. FSH acts on granulosa cells in the follicle 4. LH levels surge rapidly then decline 5. ovulation occurs 1, 2, 3, 4, 5 3, 2, 1, 4, 5 4, 3, 2, 1, 5 2, 4, 3, 1, 5 3, 1, 2, 4, 5

Chronologically arrange the events in the ovulation phase of the menstrual cycle: Ovarian follicle ruptures. Oocyte is released. Dominant follicle continues to secrete estrogen. Pituitary gland becomes more responsive to GnRH form hypothalamus. Estrogen from dominant follicle serves as positive feedback to pituitary secretion of FSH and LH.
