The vestibular folds are the superior pair of ligaments between its arytenoid cartilages and its thyroid cartilage, while the inferior pair is the vocal folds.  
The Mendelsohn Maneuver is designed to keep this structure elevated.  Both the Miller and Macintosh blades are commonly used to view this structure.  Its (*) cuneiform portion is contained in a mucous membrane anterior to its corniculate portion, which is attached to the superior section of its arytenoid portion.  Its three unpaired cartilages include the most inferior, the cricoid; the largest, named after a nearby gland; and one that funnels food into the esophagus.  The vestibular folds are the superior pair of ligaments between its arytenoid cartilages and its thyroid cartilage, while the inferior pair is the vocal folds.  For 10 points, name this structure in the airway that contains the epiglottis, Adam's apple, and vocal cords, sometimes known as the "voicebox."
