Which layer of the uterine wall is sloughed off during menstruation?

The question is incomplete as it does not have the options which are:

a: Perimetrium

b: Basal layer of endometrium

c: Myometrium

d: Functional layer of endometrium

e: Epimetrium

Answer:

d: Functional layer of endometrium

Explanation:

The uterus is the female reproductive organ which provides the site for the implantation of the zygote and development of a baby. The uterus is lined by three layer-perimetrium, myometrium and the endometrium.

The endometrium is the inner layer of the uterus which is divided into two types of layer - temporary stratum functionalis and the permanent stratum basalis.

The stratum functainalis is the thick superficial layer which is usually sloughed off during the menstruation cycle. This layer is again formed during the proliferative phase of the menstrual cycle.

Thus, Option-D is correct.
