vestibular fold

Therefore, for each second vibration of the vocal folds, the vestibular fold will complete a whole vibration cycle.

It runs between the vestibular fold, thyroarytenoid muscle, and thyroid cartilage, and is conical, bending slightly backward.

The free inferior border of the quadrangular membrane is the vestibular ligament which is the vestibular fold when covered by mucosa.

Above both sides of the vocal cord is the vestibular fold or false vocal cord, which has a small sac between its two folds (not illustrated).
