Vaginal fornix

The fornices of the vagina are the deepest portions of the vagina, extending into the recesses created by the extension of the cervix into the vaginal space.

There are three named fornices:
 * The posterior fornix is the larger recess, behind the cervix. It is close to the rectouterine pouch.
 * There are two smaller recesses in front and at the sides:
 * the anterior fornix is close to the vesicouterine pouch.
 * the lateral fornix.
