Question

Quizplus · Accepted Answer

The myometrium is the muscular layer of the uterus that is responsible for uterine contractions during labor and delivery. It is composed of smooth muscle fibers that contract rhythmically to push the fetus out of the uterus and into the birth canal. The endometrium is the innermost layer of the uterus, responsible for implantation and nourishment of a fertilized egg. The perimetrium is the outermost layer, consisting of a serous membrane that covers the uterus. There is no layer called "epimetrium."
