What is the muscle layer of the uterus called?

Endometrium
Myometrium
Perimetrium
Ureterium

The correct answer is: Myometrium

The muscle layer of the uterus is referred to as the myometrium. This layer is composed of smooth muscle tissue and plays a critical role in the contractions of the uterus during the menstrual cycle and childbirth. The myometrium's rhythmic contractions help to eject the menstrual flow and facilitate the delivery of the baby during labor. The endometrium, mentioned in the other options, is the inner lining of the uterus where implantation of a fertilized egg occurs, while the perimetrium is the outermost layer that provides protection. Ureterium is not a recognized term related to the anatomy of the uterus. Understanding the distinction between these layers is essential in grasping the physiological functions of the uterus.
