Cervical dilation
Cervical Dilation
Cervical dilation (pronounced: /ˈsɜːrvɪkəl daɪˈleɪʃən/) is a term used in obstetrics to describe the process of the cervix opening in preparation for childbirth.
Etymology
The term "cervical" originates from the Latin word "cervix" which means "neck", referring to the neck of the uterus. "Dilation" comes from the Latin "dilatare", meaning "to enlarge or expand".
Process
Cervical dilation occurs during the labor process and is measured in centimeters. When fully dilated, the cervix has expanded to about 10 centimeters in diameter to allow the baby to pass through. This process is monitored by healthcare professionals to assess the progress of labor.
