Cervical dilatation refers to the process in which the cervix, the lower part of the uterus, opens or expands in preparation for childbirth. This occurs during labor and is measured in centimeters, ranging from 0 cm (no dilation) to 10 cm (fully dilated). Dilation allows the baby to pass through the birth canal. The process of cervical dilatation is influenced by various factors, including hormones, uterine contractions, and the position of the baby. Monitoring cervical dilation is essential for healthcare providers to assess the progress of labor and determine the appropriate time for delivery.
