Which nerve mediates taste sensation from the anterior two-thirds of the tongue?
Show answer and explanation
Correct answer: C. Chorda tympani (CN VII)
- A. CN X provides taste sensation from the epiglottis area only — not the anterior tongue.
- B. CN IX mediates taste from the posterior 1/3 of the tongue (circumvallate papillae), not the anterior 2/3.
- C. Correct. The chorda tympani (branch of CN VII/facial nerve) provides taste sensation from the anterior 2/3 of the tongue, traveling with the lingual nerve.
- D. The lingual nerve carries general sensation (touch, pain, temperature) from the anterior 2/3 of the tongue, not taste.
