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
vocal process.
