Answer
The maxillae are the paired upper jaw bones-- they are the largest of the face bones. Each maxilla extends from the teeth to the inferomedial wall of each orbit.
The two foramina of the maxillae (one in each maxilla ) are the infraorbital foramina, sited just below the orbit. They permit passage of blood vessels and a nerve from the face.-- the nerve travels through the foramen rotundum of the sphenoid bone into the cranial cavity.
Work Step by Step
The inferior and superior orbital fissures are associated with the maxilla. Where the maxilla forms part of the floor of the orbit, an inferior orbital fissure opens and leads downward and medially to meet the similarly-shaped superior orbital fissure to form a v-shaped fissure that ends near the optic canal. Several nerves and blood vessels pass through the fissure-- two branches of the trigeminal nerve, (CN V), the infraorbital artery, a branch of the inferior ophthalmic vein (plus other veins).
