To examine the posterior or pharyngeal surface of the aryte-noid cartilages down to the cricoid, and obtain a good view intothe pyramidal sinuses, the voice is sounded, so as to close theglottis ; and in so doing the arytenoid cartilages approach eachother, exposing their pharyngeal surface, and separating thequadrangular membranes more widely from the plates of thethyroid.

To obtain an extended view far-ther down the trachea the mirrormust be held more perpendicularly,and a deep inspiration be made, sothat the glottis may be dilated toits fullest extent; and then, by a lit-tle manipulation, refleCtino; tlie llgllt Fig. 40-View of the left side ofthe± . * ° ° larynx (Tuerck). a. left vocal cord: o, more anteriorly, the image of several posterior-portion ofleft ventricle;c,ieft J 7 ° ventricular band : <7, posterior surface of tracheal rings comes in view as a series ep?g}^H8Le?iree,boISer of lefft aryten°- « epiglottic fold ; /,
