A member of the infrahyoid group of muscles, the thyrohyoid muscle elevates the thyroid gland while depressing the hyoid bone. These actions play a role in swallowing and speech. The thyroid gland is located in the center of the neck, just above the collarbone. The hyoid lies in the neck, just below the lower jawbone, or mandible. A small muscle, the thyrohyoid looks like a vertical extension of the sternothyroideus muscle within the neck. It originates in the thyroid cartilage (the Adamâs apple), and it inserts into the greater cornu of the hyoid bone, which is the hyoidâs back-most area.
