Which region is located between the hyoid bone and the entrance to the larynx?

• A. Nasopharynx
• B. Laryngopharynx
• C. Oropharynx
• D. Esophagus

Answer: (B)

Think of the pharynx as three zones with distinct boundaries. The laryngopharynx (hypopharynx) sits behind the larynx and runs from the epiglottis downward to where the esophagus begins. The hyoid bone serves as a superior landmark in this region, and the area ends at the laryngeal inlet (the entrance to the larynx). So the region located between the hyoid bone and the entrance to the larynx is the laryngopharynx. This part guides swallowed material toward the esophagus and is continuous with the esophagus below and the epiglottis/larynx above.
