Notes
The omohyoid muscle is a muscle at the front of the neck that consists of two bellies separated by an intermediate tendon.
The superior belly of omohyoid runs downwards from the hyoid bone, narrows to the intermediate tendon and passes through a connective tissue sling (located on the clavicle). The inferior belly continues laterally from the intermediate tendon, and is attached to the upper border of the scapula.
Omohyoid is innervated by a branch of the cervical plexus, and mostly acts to stabilise the hyoid bone.
