Which structures are included in the supraglottic region?

• A. Epiglottis
• B. Aryepiglottic folds
• C. Laryngeal ventricles
• D. All of the above

Answer: (D)

The main idea is understanding which structures sit above the true vocal cords, within the supraglottic region of the larynx.

The epiglottis forms the upper boundary of the larynx and helps protect the airway during swallowing, so it resides in the supraglottic area. The aryepiglottic folds run from the edge of the epiglottis to the arytenoid cartilages and help frame the laryngeal inlet, placing them also in this region. The laryngeal ventricles are the spaces between the false vocal cords (ventricular folds) and the true vocal cords; these ventricles lie above the true vocal cords, within the supraglottic space.

Since all three structures are located above the true vocal cords, they are all part of the supraglottic region.
