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.Fetal size does not affect dilation.Pelvic size does not affect cervical dilation.The diameters of the pelvis do not affect dilation.
