Also known as the voice box, the larynx is composed of cartilage that contains the apparatus for voice production. This includes the vocal cords and the muscles and ligaments that move the cords. Mentioned in: Cough, Croup, Epiglottitis, Laryngectomy, Laryngitis, Leishmaniasis, Tracheotomy.
Vocal Fold Paralysis. The vocal cords are two elastic bands of muscle tissue located in the voice box (larynx) directly above the windpipe (trachea). These cords allow you to speak because when air held in the lungs is released and passed through the closed vocal cords, it causes them to vibrate. When you are not speaking, the vocal cords remain apart so you can breathe. Vocal cord paralysis occurs when one or both of the vocal cords (vocal folds) do not open or close properly. The paralyzed cord or cords remain open, leaving the airway passage and the lungs unprotected. The condition makes it difficult to swallow or cough because food or liquids slip into the trachea and lungs.
