What does the genial tubercle do?

Genial tubercle – The genial tubercle is a spiny protuberance or prominence (sometimes two) of bone located in the midline on the lingual aspect of the mandible below the roots of the incisor teeth. This structure serves as the locus of attachment for the genioglossus and geniohyoid muscles.

What attached to genial tubercles?

Genial tubercles are tiny bony projections located bilaterally around the lingual foramen, on the lingual surface of the mandible giving attachment to geniohyoid inferiorly & genioglossus superiorly.
