Mandibular Torus

One of two shelf-like thickenings of bone (plural: mandibulares tori) that bridge the two sides of the mandible to the posterior of the mandibular symphysis. There are two such bony supports, or bars, which are faint in humans: the superior transverse torus, located just superior to the genial tubercles, and the inferior transverse torus, just superior to the digastric fossae, which is prominent in apes and is referred to as the simian shelf.
