Quick Summary

The thyrohyoid muscle is one of several muscles attached to the hyoid bone, a U-shaped bone in the front of the neck. This muscle originates from the thyroid cartilage, the largest cartilage of the larynx (voice box), and inserts into the hyoid bone. The hyoid bone itself serves as an anchoring structure for the tongue and other muscles, playing a role in mastication, swallowing, and voice production. The thyrohyoid muscle, along with others attached to the hyoid, helps to move the bone upward and forward, particularly during swallowing. The thyrohyoid is part of the extrinsic muscles that move the larynx as a whole.123
