The Cervix
The cervix is the entrance to the uterus that dilates before a baby is born. The dilation process can take months, or hours, as the cervix opens up to 10 centimeters.
The only way to directly check your cervix safely is at a doctor's office.
The cervix is in the very back of the vagina. It feels a little like a ball with a slit in it and serves as the entrance to the uterus. Stimulating the cervix is often described as feeling simillar to being kicked in stomach.
The cervix is located inside the cow between the vagina and the uterus. What would be the vulva at the entrance to the vagina would be the cervix--or at least the start of the cervix--at the other end. It is the organ that is essentially the "door" between the vagina and the uterus, but a 6" to 8" long cylindrical one at that.
If you are pregnant your cervix will swell and get firmer to the touch. This is due to the entrance being sealed so it now starts collecting fluids inside.
Cervix, the entrance to the uterus
Os is from the old Latin word meaning mouth. It is used today to mean an opening or entrance to a passage, esp. one at either end of the cervix of the uterus.
