Question

Quizplus · Accepted Answer

During the menstrual cycle, high levels of estrogen in the body signal the release of luteinizing hormone (LH) from the brain, which in turn stimulates the release of an egg, or ovum, from the follicle. This ovum then moves into the fallopian tubes for potential fertilization. Option B is the only choice that accurately describes this sequence. Option A is incorrect because FSH does not directly cause the release of an egg, it only stimulates the follicle. Option C is incorrect because both estrogen and progesterone levels do rise after ovulation, but it is the drop in these hormones that causes the lining of the uterus to shed. Option D is completely incorrect as fertilization of an egg would prevent menstruation from occurring.
