This area includes the opening to the bronchial tubes, the glottis, and the epiglottis as well as the voice box composed of cartilages and the vocal cords. Which region is it?

• A. The Laryngopharynx
• B. The Oropharynx
• C. The Nasopharynx
• D. The Vestibular Zone

Answer: (A)

Think about the part of the throat that serves as the passageway linking the airway to the larynx and, ultimately, to the trachea. The larynx, or voice box, is where the glottis and epiglottis live and where the vocal cords are housed in cartilaginous structures. The region that connects this airway/voice apparatus to what comes from the pharynx is the laryngopharynx. It sits just behind the larynx and acts as the conduit for air moving toward the bronchial tubes as well as for food moving toward the esophagus, which is why it’s described in terms that include both airway and laryngeal features. The other options refer to different parts of the pharynx or to a region within the larynx that isn’t the overall airway-larynx interface described here. So the best match among the choices is the laryngopharynx.
