Questions fréquentes

What is the function of the uterine cervix?
The uterine cervix acts as a gateway between the uterus and vagina. It produces mucus that changes consistency across the menstrual cycle to either facilitate or block sperm entry, and dilates during labor to allow childbirth.
Where exactly is the uterine cervix located?
The uterine cervix is the lowermost, narrow segment of the uterus. It projects into the upper vagina and is divided into the ectocervix (visible portion) and endocervix (the canal leading into the uterine cavity).
What is the transformation zone of the cervix?
The transformation zone is the area where the columnar epithelium of the endocervix meets the squamous epithelium of the ectocervix. This junction is clinically important as it is the most common site for cervical dysplasia and cancer.
