In a patient it is noticed that when he protrudes his tongue it deviates to the left. The nerve damaged is_______________?
Correct answer: A. Left hypoglossal
- A. Left hypoglossal
- B. Left glossopharyngeal
- C. Right hypoglossal
- D. Right glossopharyngeal
Explanation
Protrusion is produced mainly by the genioglossus muscles, and unilateral weakness causes the tongue to deviate toward the weak side. Thus, deviation to the left indicates damage to the left hypoglossal nerve.
