At what point does the cervix open fully during labor?

• A. First stage of labor
• B. Transition period
• C. Second stage of labor
• D. Third stage of labor

Answer: (B)

The cervix opens fully during the transition period, which is part of the first stage of labor. This transition phase is characterized by intense contractions and a significant change as the cervix dilates to its maximum of 10 centimeters. It typically occurs towards the end of the first stage of labor, just before a woman begins to push in the second stage. Understanding the stages of labor is crucial. The first stage involves the dilation and effacement of the cervix, where it progresses from being closed to fully dilated. The transition phase is the final part of this first stage, encompassing this important moment when the cervix is fully opened. In contrast, the second stage starts once the cervix is completely dilated and involves the actual delivery of the baby. The third stage follows delivery, focusing on the expulsion of the placenta.
