Mental protuberance

Side view of the skull. (Mental protuberance visible but not labeled.)
Latin	protuberantia mentalis
Gray's	subject #44 172

The symphysis of the external surface of the mandible divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle.
