Anatomical terms of muscle

The thyrohyoid muscle is a small skeletal muscle on the neck which depresses the hyoid and elevates the larynx.

This 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.

It is innervated by first cervical nerve, which joins the hypoglossal nerve for a short distance.
