The hyoid is held in position by a series of small muscles that attach to it either from above or below. But because it is near the skull, it is often discussed at the same time as the bones of the skull.The location of the larynx is at the level of the C3 to C7 vertebrae and is held into position by muscles and ligaments. The superior-most region of the larynx is the epiglottis that is attached to the hyoid bone connected to the inferior part of the pharynx. The inferior aspect of the larynx connects to the superior region of the trachea.The neck contains a pair of digastric muscles, each of which subdivides into an anterior and posterior belly. The two bellies connect by an intermediate tendon. The anterior belly of the digastric attaches near the midline of the base of the mandible on the digastric fossa and runs toward the hyoid.
