The omohyoid muscle has two bellies, the superior and inferior bellies. The two bellies are connected by an intermediate tendon, which is tethered by a fascial sling to the clavicle and first rib. The superior belly of the omohyoid muscle arises from the intermediate tendon.


The superior belly of the omohyoid muscle inserts into the inferior aspect of the body of the hyoid bone, lateral to the attachment of the sternohyoid muscle.


Overall, the omohyoid muscle depresses the hyoid bone after it has been elevated (Standring, 2016). It also fixes the hyoid bone in place with it opposes the actions of muscles that elevate the bone.
