The muscle is placed deeper than the anterior belly of the digastric muscle and the mylo-hyoid, and is in contact with the inferior border of the genioglossus muscle. Nerve-Supply.—It is supplied by the hypoglossal nerve, but its nerve can be traced back to an origin from the communication between that nerve and the first and second cervical nerves. Actions.—The digastric, stylo-hyoid, mylo-hyoid, and genio-hyoid muscles are all elevators of the hyoid bone. The posterior belly of the digastric and stylo-hyoid also retract, while the anterior belly of the digastric and the genio-hyoid protract it. The anterior belly of the digastric, mylo-hyoid, and genio-hyoid also assist in opening the mouth. The Muscles of the Tongue. M. transversus M. vertical! linguee linguae LpTirmnruydprn/-t/sj\rTJV}
