The Geniohyoid muscle is a narrow muscle situated above the medial border of the mylohyoid muscle.
It arises from the inferior mental spine on the back of the symphysis menti, and runs backward and slightly downward, to be inserted into the anterior surface of the body of the hyoid bone; it lies in contact with its fellow of the opposite side.
[edit] Variations
It may be blended with the one on opposite side or double; slips to greater cornu of hyoid bone and Genioglossus occur.
