Question

Which hormones secreted by the ovary induce development of the highlighted layer during the proliferative phase of the uterine cycle?

O estrogen progesterone
O luteinizing hormone (LH)
O follicle stimulating hormone (FSH)

Answer 1

Estrogens, such as estradiol, secreted by the ovary are responsible for the development of the uterine lining during the proliferative phase of the uterine cycle.

Step-by-step explanation:

The hormones secreted by the ovary that induce development of the uterine lining during the proliferative phase of the uterine cycle are estrogens, specifically estradiol.

During the follicular phase of the ovarian cycle, follicle-stimulating hormone (FSH) stimulates the development of the follicles, which in turn secrete estrogen.

High levels of estrogen stimulate the proliferation of the endometrial lining in preparation for potential pregnancy. This occurs before ovulation, which is triggered by the surge of luteinizing hormone (LH) resulting from the estrogen peak.
