Which layer of the uterine wall is shed in response to hormonal changes? stratum basalis perimetrium stratum functionalis myometrium?

The correct answer is stratum functionalis.

Uterus consists of three layers with distinct structural and functional characteristics. Those are

· Endometrium-mucosal layer, divided into two layers, the stratum functionalis and stratum basalis;

· Myometrium-muscularis layer and

· Perimetrium-serosal layer.

During the menstrual cycle (when hormone rise and fall) the stratum functionalis sheds whereas the stratum basalis remains relatively constant.
