The sternohyoid (sternohyoideus) is a narrow, ribbon-thin muscle located on the front of the neck. It originates on each side of the neck from the clavicle and the upper part of the first piece of the sternum (breast bone). The muscles run upward and come together in the middle of their course (both pieces of the muscle lie side by side), but do not actually touch and are inserted in the front of the hyoid bone. The muscle is innervated by the upper cervical nerves through the ansa cervicalis and is supplied by the inferior and superior thyroid arteries. This muscle pulls the hyoid bone down, as in swallowing, and assists in flexion of the head and neck. Research Sternohyoid
