The larynx is the upper expanded portion of the respiratory passageways. It is a short region defined by the laryngeal cartilages that connects the laryngopharynx to the trachea. The thyroid and cricoid cartilages form the walls of the larynx and the mucosal lining folds inward from the lateral walls to form the vocal folds. This is the site of sound production and voice and is often referred to as the voice box.
