The extrinsic muscles of the larynx are groups of muscles that act on the larynx as a whole to alter its position. Functionally they can be described as two groups of muscles:
-
infrahyoid muscles: depressors of the hyoid and larynx which are innervated by various nerves from the ansa cervicalis):
-
suprahyoid muscles: elevators of the hyoid and larynx which are innervated by various branches of the trigeminal nerve, facial nerve, glossopharyngeal nerve and ansa cervicalis :
stylopharyngeus (a pharyngeal muscle)
