Vestibule of larynx
|Vestibule of larynx|
Coronal section of larynx and upper part of trachea. (Vestibule of larynx not labeled, but visible near region labeled "Tubercle")
The portion of the cavity of the larynx above the vocal folds is called the vestibule; it is wide and triangular in shape, its base or anterior wall presenting, however, about its center the backward projection of the tubercle of the epiglottis. It contains the ventricular folds, and between these and the vocal folds are the ventricles of the larynx.
Vestibule is an opening in the lateral wall of larynx, between the vestibular fold superiorly and vocal folds inferiorly. Its the inlet to another cavity in the lateral wall of larynx, namely ventricle.The vestibular fold is formed by the vestibular ligament extending from lateral walls of epiglottis to arytenoid cartilage covered with mucous membrane.Vocal fold is the upper free margin of conus elasticus which is covered by mucous membrane.The conus elasticus forms inferiorly the lateral cricothyroid ligament.
