omohyoid muscle

The omohyoid muscle is a muscle in the neck that originates from the upper margin of the shoulder blade and the suprascapular ligament. It inserts into the hyoid bone, a U-shaped bone situated at the root of the tongue. The hyoid bone serves as an attachment for muscles of the tongue and the floor of the mouth. The omohyoid muscle, along with other muscles attached to the hyoid bone, plays a role in mastication, swallowing, and voice production. Specifically, it assists in the movement of the hyoid bone, tongue, and larynx during swallowing.1
