Quizplus · Accepted Answer

Dilation of the cervix occurs by the drawing upward of the musculofibrous components of the cervix,which is caused by strong uterine contractions.Pressure exerted by the amniotic fluid while the membranes are intact or by the force applied by the presenting part also can promote cervical dilation.Scarring of the cervix as a result of a previous infection or surgery may slow cervical dilation.Pelvic size does not affect cervical dilation.
