or voice box
Hollow, tubular structure connecting the pharynx with the trachea , through which air passes on the way to the lungs.
The larynx consists of a framework of cartilage plates, with a ridge in front (Adam's apple); the epiglottis, a flaplike projection up into the throat that covers the airway during swallowing to keep food and liquid from entering; and the vocal cords, whose vibration produces the sound of the voice (see speech ).
