Vocal cords

The pair of elastic, fibered bands inside the human larynx. The cords are covered with a mucous membrane and pass horizontally backward from the thyroid cartilage (Adam's apple) to insert on the smaller, paired arytenoid cartilages at the back of the larynx. The vocal cords act as sphincters for air regulation and may be vibrated to produce sounds. Separation, approximation, and alteration of tension are produced by action of laryngeal muscles acting on the pivoting arytenoids. Vibration of the cords produces fundamental sounds and overtones. These can be modified by the strength of the air current, the size and shape of the glottis (the opening between the cords), and tension in the cords. See Larynx, Speech

vocal cords


vocal

 [vo´kal] pertaining to the voice.vocal cords the thin, reedlike folds of mucous membrane in the larynx; the superior pair are called the false vocal cords and the inferior pair are called the true vocal cords. (See also Plates.) They vibrate to make vocal sounds during speaking, and are capable of producing a vast range of sounds. Each cord has one end attached to the front wall of the larynx, close to that of the other cord. The opposite ends are connected to two tiny cartilages near the back wall of the larynx. The cartilages can be rotated so as to swing the cords far apart or bring them together. When they are apart, the breath passes through silently, unobstructed; when they are closer together, they partly obstruct the air passage, and as the air is forced through them they vibrate like the reeds of a pipe organ and produce sound waves. These waves are what we call the voice. See also speech.Vocal cords.

vocal cords

A pair of pearly-white shelves of thin mucous membrane stretched across the interior of the LARYNX and capable of being tensioned to a widely varying degree by small laryngeal muscles. The vocal cords are caused to vibrate by the outwards passage of air from the lungs and the sound so produced is modulated by changes in the shape and volume of the mouth cavity to produce speech and song.
