Anatomy, Head and Neck, Lingual Artery
The lingual artery, which supplies the tongue as well as the oral floor, is a major branch of the external carotid artery. It appears anteromedially from the external carotid artery, at the tip of the greater horn of the hyoid bone, between the superior thyroid artery and the facial artery. The lingual artery moves medially to the hyoid bone while crossing the hypoglossal nerve (CN XII). It then courses deep to the stylohyoid and digastric muscles while subsequently passing between the middle constrictor and the hyoglossus muscles. As the lingual artery progresses to the tip of the tongue, it branches to supply the adjacent tissues. The major branches of the lingual artery include the suprahyoid artery, the dorsal lingual artery, the sublingual artery, and the deep lingual artery, also known as the ranine artery.
