Vestibular fold
The vestibular folds, also known as the ventricular folds or false vocal cords, are fold of mucous membrane within the larynx which enclose the vestibular ligaments, which are the thickened free lower edges of the quadrangular membrane. The vestibular folds extend between the thyroid and arytenoid cartilages, and lie superior and lateral to the vocal folds. The vestibular folds are called the false vocal cords as they are not responsible for sound production, rather they have a supportive role for the vocal folds instead.
The space between the two vestibular folds is known as the rima vestibuli, while the space above the vestibular folds and below the laryngeal inlet is called the laryngeal vestibule. The lateral recesses between the vestibular and vocal folds are the laryngeal ventricles.
