Quizplus · Accepted Answer

Contractions of the uterine myometrium are the key force behind pushing the baby's head or body into the cervix and through the birth canal during labor. As the myometrium contracts, it puts pressure on the baby and gradually pushes them downward, which in turn can cause the cervix to dilate and efface.
