The Thyrohyoid muscle is a small, quadrilateral muscle appearing like an upward continuation of the Sternothyreoideus. It belongs to the infrahyoid muscles group.
It arises from the oblique line on the lamina of the thyroid cartilage, and is inserted into the lower border of the greater cornu of the hyoid bone.
