Which nerve doesn't supply the laryngeal muscles?

(C) Hypoglossal nerve# Innervation of Larynx:> Larynx is innervated by branches of the Vagus nerve (CN X) on one side.> Sensory innervation to the glottis and supra-glottis is by the Internal branch of the Superior Laryngeal nerve.> External branch of the superior laryngeal nerve innervates the cricothyroid muscle.> Motor innervation to all other muscles of the larynx & sensory innervation to the subglottis is by Recurrent laryngeal nerve.> Injury to the external laryngeal nerve causes weakened phonation because the vocal cords cannot be tightened.> Injury to one of the recurrent laryngeal nerves produces hoarseness, if both are damaged the voice is completely lost and breathing becomes difficult.> Hypoglossal nerve is 12th cranial nerve, and innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve.
