The process of cervical dilation is divided into three phases:
Latent Phase: The cervix dilates from 0 to 3 centimeters. This phase is usually the longest and may last for hours or even days. Active Phase: The cervix dilates from 4 to 7 centimeters. This phase is more rapid and indicates the onset of active labor. Transition Phase: The cervix dilates from 8 to 10 centimeters. This is the final and most intense phase before the pushing stage begins.
