The endometrium is the inner lining of the uterus and thickens each month in preparation for pregnancy. If no pregnancy occurs, the endometrium is shed during menstruation. The myometrium is the muscular layer of the uterus responsible for contractions during labor. The perimetrium is the outer layer of the uterus. Mucous is a substance secreted by various glands in the body and is not a layer of the uterus.
