The uterus is made up of a body and a cervix. The cervix communicates superiorly with the uterine cavity through the internal orifice (known as internal as a communicates inferiorly with the vagina at the external orifice (known as the external os)[1][2].
The cervical canal is the narrow passage which runs through the cervix, which is what connects the vagina to the uterus. It is the lowermost part of the uterus and is consists of strong muscles.
The cervix directs the sperm to the uterus during sexual intercourse, as well as allowing the flow of menstrual blood from the uterus into the vagina.
The opening of the cervical canal is usually narrow, however, pressure from the fetal head as well as hormones found in the body can cause this opening to widen to about 4 inches. To allow the birth of a baby, the opening widens as well[3].
