Correct answer: B. Loss of the timbre of voice
- A. Hoarseness
- B. Loss of the timbre of voice

The external laryngeal nerve supplies the cricothyroid muscle, which tenses the vocal folds and raises pitch. Injury therefore causes loss of high-pitched sounds and altered voice timbre rather than laryngeal anesthesia.
