What is the term for the point when the baby's head is visible at the birth canal?

Crowning refers to the moment during childbirth when the widest part of the baby's head becomes visible at the vaginal opening, signaling that delivery is imminent. This stage is crucial as it indicates that the baby is descending through the birth canal and will soon be born. Crowning often occurs just before the mother begins to push, and it gives healthcare providers important information about the progress of labor.

Understanding the stages of labor is essential for emergency medical responders, as recognizing crowning can help them assess the situation and prepare for potential immediate delivery. Descent describes the process of the baby moving down the birth canal, while engagement refers to the fetal presenting part entering the pelvic inlet, both of which occur prior to crowning. Delivery refers to the actual expulsion of the baby after crowning has occurred. Thus, crowning is a specific term that highlights a significant milestone in the birthing process.
