Quizplus · Accepted Answer

Damage to the facial nerve can result in facial paralysis or weakness on the affected side of the face, which can cause an inability to close the eye (due to weakness of the orbicularis oculi muscle) and drooping of the corner of the mouth (due to weakness of the muscles of facial expression). Hypoglossal nerve damage would affect tongue movement, accessory nerve damage would affect shoulder movement, and glossopharyngeal nerve damage would affect swallowing and taste sensation.
