Question

Injury to vagus nerve in humans is not likely to affect _____________.

• A. tongue movements
• B. gastrointestinal movements
• C. breathing
• D. cardiac movements.

Vagus nerve innervates the pharynx, larynx, oesophagus, stomach, lungs, heart and intestines.Thus injury to vagus nerve will not affect tongue movements as it does not innervate tongue.
