Which nerve is a branch of the maxillary division (V2)?

• A. Infraorbital Nerve
• B. Inferior Alveolar Nerve
• C. Mental Nerve
• D. Mylohyoid Nerve

Answer: (A)

The maxillary division (V2) supplies the midface, and the infraorbital nerve is a direct branch of V2. It travels through the infraorbital canal and exits the infraorbital foramen to provide sensation to the lower eyelid, side of the nose, and upper lip. The other nerves listed come from the mandibular division (V3): the inferior alveolar nerve runs in the mandibular canal to the lower teeth, the mental nerve (a branch of the inferior alveolar nerve) supplies the chin and lower lip, and the mylohyoid nerve arises from the inferior alveolar nerve to innervate the mylohyoid muscle. So, the infraorbital nerve is the branch of V2.
