The roof of the orbit is bounded by an orbital palate of the frontal bone in front and lesser wing of sphenoid from behind separating from ant cranial. Fossa floor is formed by an orbital palate of maxilla separating it from the maxillary antrum. The floor of the orbit is the roof of the maxillary antrum.
The medial wall of orbit bones taking part are the frontal process of maxilla crust of lacrimal bone. The orbital palate of ethmoid separating it from ethmoid air sinus body of sphenoid bounded behind by tiny piece of bone which lies at the apex of the orbit. Orbital process of the palatine bone, lateral wall is bounded by zygomatic and greater wing of sphenoid separating it from the temporal fossa.
