cervix
n. countablen. the narrow, lower part of the womb that connects to the vagina. It acts like a doorway that opens and closes during different stages of life, such as during childbirth.
n. the narrow neck-like passage forming the lower end of the uterus. It serves as the anatomical junction between the uterine cavity and the vaginal canal.
The doctor checks the health of the cervix during a routine exam.
During the final stages of labor, the cervix must dilate to ten centimeters to allow the baby to pass through.
Regular screening via a Pap smear is essential for detecting abnormal cellular changes in the cervix before they develop into more serious conditions.
Borrowed from Latin cervīx (“neck”), see below.
The plural form is either 'cervixes' or the more formal, Latin-derived 'cervices'.
