The maxillary process is associated with which division of the trigeminal nerve?

• A. V1
• B. V2
• C. V3
• D. V1 and V2

Answer: (B)

The maxillary process aligns with the maxillary division of the trigeminal nerve. This division, V2, is the sensory pathway to the midface, including the maxilla, upper teeth and gums, palate, and parts of the nasal cavity and maxillary sinus. The maxillary process forms the upper jaw region, so its innervation comes from V2. By contrast, V1 supplies the forehead and orbit, and V3 supplies the lower face and muscles of mastication, so they’re not associated with the maxillary process. V2 exits the skull via the foramen rotundum and then reaches the midface to provide these sensory innervations.
