The posterior portion of the palate that elevates to close off the nasopharynx during swallowing is the?

• A. Hard palate
• B. Uvula
• C. Soft palate
• D. Epiglottis

Answer: (C)

During swallowing, the soft palate elevates to seal off the nasopharynx, preventing food from refluxing into the nasal cavity and guiding the bolus toward the oropharynx. This elevation is carried out by the muscles of the soft palate, especially the levator veli palatini. The uvula is a part of the soft palate and can contribute to the seal, but the key structure that actually lifts to close the nasopharynx is the soft palate itself. The hard palate is rigid and does not move to close the nasopharynx, and the epiglottis protects the airway rather than closing the nasopharynx.
