Where is the genial tubercle located?

The genial tubercle is specifically located on the mandible, which is the lower jawbone in humans. It manifests as a small bony prominence on the lingual surface (the side facing the tongue) of the anterior portion of the mandible. This anatomical structure serves as an attachment point for the genioglossus muscle, which plays a critical role in tongue movement and positioning.

Recognizing that the genial tubercle is on the mandible helps clarify its function and significance in oral and dental anatomy. The other options reference different bones or areas within the facial structure that do not relate to the genial tubercle, thereby distinguishing the mandible as the correct anatomical location for this feature.
