A mental spine is a small projection of bone on the posterior aspect of the mandible (lower jaw bone) in the midline. The adjective mental in this instance is used in its "chin-related" sense (from Latin mentum) rather than its more common "mind-related" sense (from Latin mens). There are usually four mental spines: two superior and two inferior. Collectively they are also known as the genial tubercle,[1] genial apophysis and the Latin name spinae mentalis. The inferior mental spines are the points of origin of the geniohyoid muscle,[2] one of the suprahyoid muscles and the superior mental spines are the origin of the genioglossus muscle, one of the muscles of the tongue.
