A patient cannot taste the anterior two-thirds of the tongue after facial nerve damage. Which nerve pathway is most closely involved?
Correct answer: A. Chorda tympani branch of the facial nerve
- A. Chorda tympani branch of the facial nerve
- B. Tibial branch of the sciatic nerve
- C. Phrenic nerve from the cervical plexus
- D. Greater occipital nerve from the spinal cord
Explanation
Taste from the anterior two-thirds of the tongue travels through the chorda tympani branch of cranial nerve VII, the facial nerve. General touch from this region mainly travels through the lingual branch of the mandibular division of the trigeminal nerve.
