The larynx (/ËlÃ¦rÉªÅks/; plural larynges; from the Greek Î»Î¬ÏÏÎ³Î¾ lÃ¡rynx), commonly called the voice box, is an organ in the neck of tetrapods involved in breathing, sound production, and protecting the trachea against food aspiration.
Larynx, also called voice box, a hollow, tubular structure connected to the top of the windpipe (trachea); air passes through the larynx on its way to the lungs. The larynx also produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts. The larynx is composed of an external skeleton of cartilage plates that prevents collapse of the structure. The plates are fastened together by membranes and muscle fibres.
