Cervical dilation (or cervical dilatation) is the opening of the cervix, the entrance to the uterus, during childbirth, miscarriage, induced abortion, or ...
Hegar dilators are used to induce cervical dilation in order to gain entry to the interior of the uterus. During the process of dilation, the cervix may have to be stabilized with a tenaculum , and then the dilators are slowly entered into the cervical canal with a lubricant, starting with a thin, low Hegar number rod and progressing gradually ...

[3] In cases of cervical weakness, dilation and effacement of the cervix may occur without pain or uterine contractions. In a normal pregnancy, dilation and effacement occurs in response to uterine ...
