Question

the thick, smooth, middle muscular layer of the uterus is called the:
a. endometrium.
b. fundus.
c. myometrium.
d. perimetrium.

Explanation:

The uterine wall has three layers: the inner endometrium, the middle myometrium (smooth muscle layer), and the outer perimetrium. The question asks for the middle muscular layer, so the correct term is myometrium. Option C is myometrium, which matches the description of the middle muscular layer of the uterus. Option A (endometrium) is the inner lining, Option B (fascia) is not a uterine layer, and Option D (perimetrium) is the outer layer.

Answer:

C. myometrium.
