During which labor stage does the cervix fully dilate?

The cervix reaches full dilation during the transition stage of labor, which typically occurs within the first stage of labor but is specifically marked as the moment when the cervix dilates to 10 centimeters. This transition stage represents a critical phase where the body prepares for the delivery of the baby.

During the first stage of labor, which consists of the latent and active phases, the cervix gradually dilates from 0 to 10 centimeters. The transition stage occurs at the end of this first stage, characterized by more intense contractions and significant physiological changes as the mother nears the delivery of the baby. It is a crucial time, often associated with a significant change in the mother's experience, as they may feel increased pressure and urgency.

The second stage of labor follows the transition stage and involves the actual delivery of the baby, whereas the third stage is focused on the delivery of the placenta. Understanding these stages helps clarify the important milestones in the childbirth process.
