Relaxed vocal cords. Endoscope view of the inside of a larynx (voicebox), showing the human vocal cords in the normal respiratory position. In this position the vocal cords are relaxed, allowing air to pass backwards and forwards without producing any vocal sounds. The larynx is the lower part of the throat. When the vocal cords are tensed (see P496/030), they close up, causing air passing outwards from the lungs to resonate and vibrate. This produces vocal sounds, such as singing and speech. An endoscope is a tube, with a camera on its tip, used to examine the inside of the body.
