Question

Answer 1

The myometrium is the muscle layer of the uterus, responsible for contractions during labor and menstruation, and is situated between the inner endometrium and the outer perimetrium. Option d.

Step-by-step explanation:

The myometrium is the muscle layer of the uterus and is crucial for uterine contractions during labor and menstrual cycles.

This middle layer is comprised mostly of smooth muscle tissues which are organized in patterns that enable contractions to happen from various directions, aiding in both childbirth and the expulsion of menstrual blood.

The uterus, an organ approximately the size of a woman's fist, supports the developing fetus during pregnancy with its three layers: the inner endometrium, the muscular myometrium, and the outer perimetrium.

So option d.
