Quizplus · Accepted Answer

Difficulty in swallowing (dysphagia) is often associated with damage to the vagus and glossopharyngeal nerves, both of which play a role in controlling the muscles involved in swallowing. The facial nerve, on the other hand, does not have a direct role in swallowing, but damage to this nerve can result in problems with drooling or difficulty controlling food in the mouth, which can indirectly affect swallowing. Therefore, the best choice is E - vagus and glossopharyngeal only.
