Which tissue forms the muscular layer responsible for contractions?

Explanation:
The muscular layer that generates contractions is the myometrium. It’s the thick middle layer of the uterus made up of smooth muscle arranged in intertwined fibers, allowing coordinated, rhythmic contractions essential for labor and menstrual cramps. The inner lining, the endometrium, is not a muscle and thickens or sheds with the cycle. The outer covering, the perimetrium, is a serous layer, and the cervix refers to the lower part of the uterus, not the muscular contractile wall. So the tissue forming the muscular layer responsible for contractions is the myometrium.
