vestibular folds การใช้

• These folds are false vocal folds ( vestibular folds ) and true vocal folds ( folds ).
• Therefore, for each second vibration of the vocal folds, the vestibular fold completes a whole vibration cycle.
• It runs between the vestibular fold, thyroarytenoid muscle, and thyroid cartilage, and is conical, bending slightly backward.
• By constricting the larynx, the vestibular folds can be brought together ( adducted ) and, under certain conditions, vibrate.
• The vestibule is an opening in the lateral wall of the larynx, between the vestibular fold above and the vocal folds below.
• The vocal folds are sometimes called'true vocal folds'to distinguish them from the'false vocal folds'known as vestibular folds or " ventricular folds ".
• 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 is the inlet to another cavity in the lateral wall of larynx, the laryngeal ventricle . The vestibular fold is formed by the vestibular ligament extending from the lateral walls of the epiglottis to the arytenoid cartilage covered with mucous membrane.
