Uterine gate

The cervix has a double meaning. It is either a "closed throat" during childbirth (= birth gate), or an "internal and external gate" closing the cervical canal from both sides until the throat begins to open for childbirth.



Inner goal
The internal gate delimits the entrance to the cervical canal from the uterus.

Outer goal
The external gate limits the exit from the cervical canal towards the vagina.

Sore throat
During childbirth, the cervix gradually disappears. The inner gate merges with the outer gate into one gate (= obstetric gate), which then opens and allows the baby to enter the pelvic entrance.
