The sternohyoid muscle's main function is the depression of the hyoid bone. The hyoid bone is located below the mandible, or lower jaw, and is a U shaped bone that is partially responsible for tongue movement and the action of swallowing. The sternohyoid is one of a pair of muscles responsible for this action.
Geniohyoid Muscle. Geniohyoid Muscle: The geniohyoid muscle is one of the suprahyoids, a group of paired muscles of the anterior neck located above the hyoid bone. The geniohyoid muscle inserts on the hyoid bone. The geniohyoid muscle elevates the hyoid bone while swallowing. It is innervated by the hypoglossal nerve. Conditions that can afflict the s geniohyoid muscle include overuse injuries, tears, strains, myopathy, atrophy, infectious myositis, neuromuscular diseases, lacerations and contusions.
