The surge in LH that occurs during the middle of the ovarian cycle triggers:• Menstruation.O Ovulation.O Follicle Maturation.O Atresia.• Menopause

In the human ovarian cycle, ovulation is triggered by a sharp rise in luteinizing hormone (LH). What is the cause of this sharp rise?

During which stage of the ovarian cycle will LH spike?Multiple Choiceovulationfollicular phaseluteal phasesecretory phaseproliferative phase

Select all events that occur during the follicular phase (first half) of the ovarian cycle.Multiple select question.Ovarian follicles develop.Corpus luteum develops.Blood progesterone increases.Blood estrogen increases.GnRH from the hypothalamus increases.

Ovulation takes place due to the rapid secretion of LH in female primates

Which one of the following statements regarding the female menstrual cycle is INCORRECT?Question 1Select one:a.The large decrease in estrogen and progesterone towards the end of the luteal phase leads to deterioration of the endometrium and menses. b.During the follicular phase, FSH and LH stimulate growth of granulosa cells in the follicle.c.Granulosa cells produce estradiol during the follicular phase that exerts negative feedback on the hypothalamus and pituitary gland to reduce LH and stimulate ovulation.d.During the luteal phase, the corpus luteum makes progesterone and estradiol.e.Gonadotropin releasing hormone (GnRH) from the hypothalamus triggers the release of follicle stimulating hormone (FSH) and luteinising hormone (LH).
