spongy layer of vagina
Definition: inappropriate collective reference to the abundant venous plexuses of the vagina, occurring within the mucosal and muscular layers (giving the rugae a character similar to erectile tissue) as well as in the adventitia (the laterally placed vaginal venous plexuses), falsely suggesting a discrete layer of erectile tissue.
