Definition: The expanded upper end of the windpipe or trachea,
connected with the hyoid bone or cartilage. It contains the vocal
cords, which produce the voice by their vibrations, when they are
stretched and a current of air passes between them. The larynx is
connected with the pharynx by an opening, the glottis, which, in
mammals, is protected by a lidlike epiglottis.
