Which nerve provides sensory innervation to the upper eyelid?

  1. Ophthalmic division of the trigeminal nerve (V1)
  2. Mandibular division of the trigeminal nerve (V3)
  3. Maxillary division of the trigeminal nerve (V2)
  4. Facial nerve (VII)
Show answer and explanation

Correct answer: A. Ophthalmic division of the trigeminal nerve (V1)

  • A. Correct. The UPPER eyelid is supplied by V1 (ophthalmic), via its supraorbital, supratrochlear, and lacrimal branches. Useful contrast: the LOWER eyelid is supplied by V2 (maxillary) via the infraorbital nerve — which is why an infraorbital block anesthetizes the lower lid.
  • B. V3 supplies the lower face, mandibular teeth, and anterior two-thirds of the tongue (general sensation).
  • C. V2 supplies the LOWER eyelid, upper lip, lateral nose, and maxillary teeth.
  • D. The facial nerve is MOTOR to the eyelid (orbicularis oculi closes the eye) — it carries no sensation from the lid.
