The vestibular fold (ventricular fold, superior or false vocal cord) is one of two thick folds of mucous membrane, each enclosing a narrow band of fibrous tissue, the vestibular ligament, which is attached in front to the angle of the thyroid cartilage immediately below the attachment of the epiglottis, and behind to the antero-lateral surface of the arytenoid cartilage, a short distance above ...
The 'true vocal cords' are distinguished from the 'false vocal folds', known as vestibular folds or ventricular folds, which are located slightly superior to the more delicate true folds. While the false vocal folds play a minimal role in normal phonation, they can produce deep sonorous tones, screams and growls.
It is to the vestibular ligaments (vestibular folds once covered with mucous membrane) what the rima glottidis is to the vocal ligaments (vocal folds once covered with mucous membrane) – the space formed when the folds are separated. It can be defined as the space in between the false vocal cords, and allows air to pass through the larynx.
The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms produced from the same general area of the body involve the production of unvoiced consonants , clicks , whistling and whispering .)
The vestibular folds are not responsible for sound production, but rather for resonance. The exceptions to this are found in Tibetan chanting and Kargyraa, a style of Tuvan throat singing. Both make use of the vestibular folds to create an undertone. These false vocal cords do not contain muscle, while the true vocal cords do have skeletal muscle.
“For example, bats can make low frequency calls, using their so-called ‘false vocal folds’ – like human death metal singers do.” Together the normal vocal range for a bat spans 7 octaves ...
Surgery of the vocal folds can disturb this layer with scar tissue, which can result in the inability of the epithelium to retain an adequate mucous coat, which will in turn impact lubrication of the vocal folds. The epithelium has been described as a thin shell, the purpose of which is to maintain the shape of the vocal fold.
Harsh voice includes the use of the ventricular folds (the false vocal cords) to damp the glottis in a way similar to what happens when a person talks while lifting a heavy load, or, if the sound is voiceless, like clearing one's throat.
