The Epiglottis of the Larynx
Vocal Cords (Vocal Folds) & Vestibular Folds of the Larynx
- Each fold extends from the back of the thyroid cartilage to the front of the arytenoid cartilage.
- The inferior set of folds are called the vocal folds or vocal cords (= true vocal folds).
- A narrow vocal ligament is embedded in each vocal fold. These elongated bands of elastic tissue vibrate to produce voice sounds (= phonation).
Have you been making any of these common anatomy learning mistakes?
- 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 vestibular folds (= false folds or ventricular folds).
- Each vestibular fold is formed by a thick layer of mucous membrane (= respiratory membrane) and a supportive vestibular ligament.
- 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.
