GENIOGLOSSUS

The genioglossus (geniohyoglossus) is a flat triangular muscle that originates from the inner surface of the front of the mandible (lower jaw) and the hyoid bone and inserts in the tongue, from the apex (tip) to the base. There are two genioglossus muscles, one on each side of the tongue. When the two muscle contract at the same time, the tongue is protruded by its whole foundation being pulled forward. This muscle is innervated by the hypoglossal nerve. The
genioglossus, the styloglossus, the palatoglossus and the hyoglossus work together to move the tongue.
