|Vocal Cord Disorders
The vocal cords (also called vocal folds) are 2 bands of smooth muscle tissue found in the larynx (voice box). The larynx is set in the neck at the top of the trachea (windpipe). The vocal cords vibrate and air passes through the cords from the lungs to produce the sound of your voice. The sound is then sent through the throat, nose, and mouth, giving the sound "resonance." The sound of each person's voice is determined by the size and shape of the vocal cords and the size and shape of the throat, nose, and mouth. Vocal cord disorders affect the vocal cords.
