What is the leaf-shaped structure located superior to the larynx called?

• A. Epiglottis
• B. Uvula
• C. Esophagus
• D. Thyroid cartilage

Answer: (A)

The leaf-shaped structure located just above the larynx is the epiglottis. It’s a flap of elastic cartilage that sits at the opening of the larynx and acts as a switch between air passage and swallowing. When you breathe, the epiglottis stands upright to allow air into the trachea; when you swallow, it folds down to cover the glottis, directing food and liquid into the esophagus and protecting the airway. The uvula hangs from the soft palate, the esophagus is the tube that carries swallowed material to the stomach, and the thyroid cartilage is the shield-shaped piece that forms part of the larynx—none of these are leaf-shaped or located directly superior to the larynx like the epiglottis.
