NEET PG DENTAL EXAM

Detailed explanation-1: -The flap that covers the trachea during swallowing so that food does not enter the lungs. Anatomy of the larynx.

Detailed explanation-2: -It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along the oesophagus toward the stomach instead. It is thus the valve that diverts passage to either the trachea or the oesophagus.

Detailed explanation-3: -During pharyngeal swallow, the soft palate elevates and the tongue retracts, closing the pharyngeal space. The tongue and soft palate also play an important role in controlling upper airway patency.
