Question

What is the thickest portion of the uterine wall?
A) functional layer of the endometrium
B) basal layer of the endometrium
C) myometrium
D) perimetrium
E) epimetrium

Accepted Answer

The myometrium is the thickest layer of the uterine wall, consisting of smooth muscle tissue. This layer is responsible for the contractions that occur during labor and delivery. The functional layer of the endometrium is shed during menstruation and is relatively thin compared to the myometrium. The basal layer of the endometrium is thin and serves as the source of new endometrial tissue after menstruation. The perimetrium is the outer layer of the uterus and is thin, while the epimetrium is not a recognized component of the uterine wall.
