Question

Which uterine layer is composed of a simple columnar epithelium containing tubular glands?

Answer 1

The uterine layer that is composed of a simple columnar epithelium containing tubular glands is the endometrium. It is the mucous membrane that lines the inside of the uterus. It is the innermost glandular layer and functions as a lining for the uterus, preventing adhesions between the opposed walls of the myometrium and hence maintaining the patency of the uterine cavity.

Answer 2

The correct answer is endometrium.

The endometrium is one of the three layers of uterine (myometrium and perimetrium are another two). It is the inner epithelial layer which contains a basal layer and a functional layer. The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer. The functional layer thickens and then sheds during the menstrual cycle. During the pregnancy, the uterine glands (tubular) of the functional layer increase in size and number.
