The larynx is an anatomically complex organ of the upper airway that lies at the crossroads of the up-per aerodigestive tract and the tracheobronchial tree. It connects the pharynx with the cervical tra-chea and serves several key functions related to normal respiration, swallowing, airway protection, and phonation.
