The musculus palatoglossus ( Latin for "palate-tongue-muscle") is a skeletal muscle of the head. It arises as a splitting off of the transversus linguae muscle and radiates into the palate - aponeurosis . It forms the muscular basis of the anterior palatal arch ( arcus palatoglossus ). The muscle lifts the base of the tongue, closes the mouth ( isthmus faucium ) during the act of swallowing and lowers the palate.
The innervation occurs via the vagus nerve , possibly also via the radix cranialis of the accessory nerve , other authors on the other hand indicate the pharyngeal plexus of the glossopharyngeal nerve .
