The vocal cords are an essential part of phonation (speech).
Structure of the vocal cords
The vocal cords are contained in the larynx and are tightened folds of the laryngeal mucosa. There are two vocal cords each measuring 1 to 2 centimetres between which is a gap through which air can pass to reach the lungs.
Function and functioning of the vocal cords
When air is expired, the vocal cords vibrate to produce sounds.
