What is Cervix

Cervix - The neck of the UTERUS, a thick cuff of muscular tissue about one inch in length that joins the VAGINA to the uterus. A narrow channel through the cervix, the cervical canal, allows menstrual material to leave and SPERM to enter the uterus. The opening of the cervix within the uterus is the internal os; the opening of the cervix within the vagina is the external os. The cervix has the ability to thin and dilate to permit CHILDBIRTH.

HEALTH CONDITIONS THAT MAY AFFECT THE CERVIX
CERVICAL CANCER cervical DYSPLASIA
cervical erosion CERVICAL INTRAEPITHELIAL NEOPLASIA (CIN)
