What Bones Form The Orbit. Orbital plate of the frontal bone. Web there are seven bones that contribute to the bony orbit:

Lesser wing of the sphenoid bone. The frontal, sphenoid, zygomatic, ethmoid, lacrimal, palatine and maxilla bones. Frontal, ethmoid, palatine, lacrimal, maxilla, zygomatic, and sphenoid. Yellow = frontal bone green = lacrimal bone brown = ethmoid bone blue = zygomatic bone purple = maxillary bone aqua = palatine bone red = sphenoid bone teal = nasal bone (illustrated but not part of the orbit) It is our job as ophthalmologists to be able to readily identify these bones and know pretty much every bump, notch, hole, and contour of these bones and what structures pass through, travel along, and attach to these bones.

The borders and anatomical relations of the bony orbit are as follows: Each of these plays a role in keeping the eyeball protected. Formed by the lesser wing of the sphenoid and the frontal bone. Formed by the greater wing of the sphenoid bone and the zygomatic bone. Yellow = frontal bone green = lacrimal bone brown = ethmoid bone blue = zygomatic bone purple = maxillary bone aqua = palatine bone red = sphenoid bone teal = nasal bone (illustrated but not part of the orbit) Web the bones of the orbit develop via both endochondral and intramembranous ossification.
