The term "false vocal cord" refers to a pair of delicate muscular folds located within the larynx, situated above the true vocal cords. Also known as "vestibular folds," they do not participate in the production of sound during vocalization. The false vocal cords are named as such due to their resemblance to the true vocal cords, despite serving different purposes.
These folds play a primarily protective role, aiding in the prevention of foreign substances from entering the lower respiratory tract. During swallowing, the false vocal cords close, assisting in the closure of the entrance to the windpipe, known as the glottis. This helps to prevent food and liquids from entering the lungs. Additionally, the false vocal cords can act as a protective mechanism during periods of intense coughing, as they partially close off the windpipe, minimizing the possibility of aspiration.
Despite not being involved in sound production, the false vocal cords may have some secondary functions. They are occasionally utilized to create certain sounds during speech or singing, such as in whispering or throat singing techniques. Moreover, they can contribute to resonance and tone modification, enhancing the quality and character of the produced sounds.
In summary, the false vocal cords are a pair of muscular folds positioned above the true vocal cords. Primarily serving a protective role, they assist in safeguarding the respiratory system from foreign substances. While not directly involved in sound production, they have secondary functions that can influence the vocal qualities and may be used in certain vocal techniques.
