Multiple Choice

The laryngeal inlet is bounded laterally by which structures?

The laryngeal inlet is the opening between the pharynx and the larynx, and its sides are defined by the aryepiglottic folds. These folds stretch from the epiglottis to the arytenoid cartilages, outlining the lateral rim of the inlet. The epiglottis sits at the front as the anterior boundary, helping protect the airway during swallowing. The vocal cords are deeper inside the larynx and form the glottis, not the inlet’s lateral margin, and the cricoid cartilage is part of the lower laryngeal framework rather than forming the side boundary. So the structures that bound the laryngeal inlet on the sides are the aryepiglottic folds.
