The cervix is the lower part of the uterus (womb), situated on top of the vagina. It has a round shape and is approximately 1 inch long in non-pregnant women.
Through the cervix runs the narrow cervical canal, and this is where the menstrual blood and the fetus leave the womb to go into the vagina. The dilation of the cervix is an indicator if a woman is in labour. The top part of the cervical canal (opening into the uterus) is called internal orifice and lower part (opening to the vagina) is called external orifice. [1]
This also allows sperm to go from the vagina into the uterus; many methods of contraception work by blocking the passage of the sperm through the cervical canal. [2]
Some problems that may occur in the cervix are:
- Cervicitis
- Cervical incompetence
- Cervical polyps and cysts
- Cervical cancer (this can be screened with a PAP smear)
- Cervical inflammation
- Cervical intraepithelial neoplasia (CIN)
- Cervical polyps
- Cervical pregnancy
- Cervical dysplasia [3]
