Vocal Cords (Vocal Folds) & Vestibular Folds of the Larynx

  • Projecting into the lumen of the larynx are  image descriptiontwo pairs  of soft tissue folds.

  • Each fold image descriptionextends from the back of the thyroid cartilage to the front of the arytenoid cartilage.

  • The inferior set of folds are called the image descriptionvocal folds or vocal cords (= true vocal folds).

  • A narrow image descriptionvocal ligament is embedded in each vocal fold. These elongated bands of elastic tissue vibrate to produce voice sounds (= phonation).

  • Unlike the rest of the larynx, the surfaces of the vocal folds are covered by a protective layer of stratified squamous epithelium.
  • Superior to the vocal folds are the  image descriptionvestibular folds  (= false folds or ventricular folds).

  • The vestibular folds are not directly involved in the process of voice production.
  • Instead, they lubricate the vocal folds with mucous sections and help prevent food from entering the lower respiratory tract organs.
