The laryngeal muscles of the phonatory system are comprised of a group of both intrinsic and extrinsic muscles. Out of these two muscle groups, the placement of the extrinsic muscles are what confuse me the most. The extrinsic laryngeal muscles are further divided into suprahyoid and infrahyoid muscles. The suprahyoid muscles attach superiorly to the hyoid bone and elevate the larynx and hyoid bone, while the infrahyoid muscles attach inferiorly to the hyoid bone and depress the larynx and the hyoid bone.
