The endometrium is the inner lining of the uterus that thickens during the menstrual cycle in preparation for a possible pregnancy. If pregnancy does not occur, the endometrium is shed during menstruation. The perimetrium is the outer layer of the uterus, while the myometrium is the muscular layer responsible for the contractions during labor. The perineum is the area between the vaginal opening and the anus.
