ANATOMY AND PHYSIOLOGY OF THE LARYNX AND LARYNGOPHARYNX (HYPOPHARYNX) The larynx
The larynx guards the upper airway and produces the voice. It communicates above with the oropharynx, and below it is continuous with the trachea. It has a skeleton consisting of the thyroid cartilage and the cricoid cartilage. Above, it is suspended from the hyoid bone by the thyrohyoid muscle (Figure 77).
