Describe the structure and function of the larynx with regard to the production of sound.
The cartilage-encased larynx, also known as the Adam's apple, functions as the voice box. When air passes through the larynx, the air causes the two elastic ridges or vocal chords that stretch across the larynx to vibrate, producing sound. Changes in the tension of the chords effect changes in the pitch of the sounds produced.
