Which foramen is associated with the maxillary division exit?

• A. Foramen rotundum
• B. Foramen ovale
• C. Superior orbital fissure
• D. Foramen spinosum

Answer: (A)

The maxillary division exits the skull through the foramen rotundum. This opening in the sphenoid bone is the specific passage from the middle cranial fossa to the pterygopalatine fossa for V2. The other openings correspond to other branches or structures: the foramen ovale transmits the mandibular division (V3); the superior orbital fissure transmits the ophthalmic division (V1) along with several cranial nerves; and the foramen spinosum carries the middle meningeal vessels and small branches, not V2. So the foramen rotundum is the correct exit route for the maxillary division.
