Latin	cavitas laryngis
Gray's	subject #236 1078

The laryngeal cavity (cavity of the larynx) extends from the laryngeal entrance to the lower border of the cricoid cartilage where it is continuous with that of the trachea.

It is divided into two parts by the projection of the vocal folds, between which is a narrow triangular fissure or chink, the rima glottidis.

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.

The portion below the vocal folds is called the infraglottic cavity. It is at first of an elliptical form, but lower down it widens out, assumes a circular form, and is continuous with the tube of the trachea.
