Voice Box
The voice box or larynx consists of rings of dense tissue called cartilage, some of which can be seen in a structure known as the Adam's apple, which in men sticks out at the front of the neck just below the chin.
Within the voice box are two sheets of fibrous material that stretch across the rings of cartilage.
These are the vocal cords, and their main function is voice production. Air from the lungs passes across the vocal cords, causing them to vibrate, and these vibrations are modified by the tongue, palate and lips to produce speech.
Sounds vary according to the position of the cords. The vocal cords also prevent food entering the lungs.
