• A. Myometrium
• B. Endometrium
• C. Perimetrium
• D. Cervix

Answer: (A)

Think about the three main layers of the uterus. The muscular middle layer, called the myometrium, is made of thick smooth muscle arranged in layered bundles that can contract powerfully and rhythmically. These contractions drive labor and help expel the uterine contents, while also supporting movement during the menstrual cycle. The inner lining, the endometrium, thickens and sheds with hormones, and the outer covering, the perimetrium, protects the uterus. The cervix is the lower part connecting the uterus to the vagina, not a wall layer. So the muscular middle layer is the myometrium.
