A fossa (Latin for “trench”) between the true and false vocal folds, running in an anteriorposterior direction. The laryngeal ventricle is bounded laterally by a mucus membrane, beyond which is the inner surface of the thyroid cartilage. At the anterior end of the ventricle is the opening of the laryngeal saccule (or laryngeal “appendix”).
