The stratum functionalis of the endometrium is the layer that is shed each month during menstruation. This layer is composed of the functional layer of epithelial and stromal tissue that responds to hormonal changes and supports implantation of a fertilized egg. The stratum basalis, on the other hand, is the basal layer of the endometrium that gives rise to the stratum functionalis and is not shed during menstruation. The myometrium is the smooth muscle layer of the uterus that contracts during labor and delivery, and the perimetrium is the outer layer that covers the uterus.
