Question

Quizplus · Accepted Answer

The myometrium is the middle and thickest layer of the uterus and is made up of muscle tissue. This layer contracts during menstruation to expel menstrual fluid and during labor to push the fetus out of the womb. The other options (perimetrium, endometrium, perineum) do not have a role in these processes.
