The orbit is formed by six bones: frontal, maxilla, zygomatic, sphenoid, lacrimal and ethmoid. The palatine bones are sometimes included as well, as they make small contribution to the floor of the orbit. The orbits have a pyramidal shape with a roof, floor, medial wall and lateral wall. The apex of the pyramid is directed posteromedially. The nasal bones and inferior nasal conchae, which are not part of the orbit, are also shown in the model.
