Question

Quizplus · Accepted Answer

The secretory phase of the uterine cycle is the endometrial response to progesterone, which causes the thickening of the endometrial lining in preparation for possible implantation of a fertilized egg. It follows the proliferative phase and occurs after ovulation. Choice B is incorrect because the menstrual phase comes before the proliferative phase, not after the secretory phase. Choice C is incorrect because the corpus albicans is a remnant of a ruptured follicle in the ovary and does not have a direct effect on the endometrium. Choice D is incorrect because the adenohypophyseal response is related to the menstrual cycle, not the uterine cycle.
