Rugae are found in places like the vagina, bladder, and stomach and are more of a feature artifact of wall function than functional structures in and of themselves.
What I mean by artifact is that by identifying rugae, you are simply recognizing the folds in the unstretched wall that underlie the ability of the walls to expand. These walls can expand significantly as these rugae flatten out when the walls are distended by pressure due to increased volume occupying the lumen of the hollow organ.
