Bones That Form The Orbit. Web the bony orbits (or eye sockets) are bilateral and symmetrical cavities in the head. The sphenoid and ethmoid bones form mostly via endochondral ossification while the frontal bone is formed by intramembranous ossification.

Web start studying bones that form the orbit part 1. Web the following seven bones form the orbit: Optic foramen orbital margin (rim): Maxilla, frontal bone, zygomatic bone, ethmoid bone, lacrimal bone, sphenoid bone, and palatine bone. The orbit is made up of portions of both the cranial and the facial skeletal systems. 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. Web the bony orbits (or eye sockets) are bilateral and symmetrical cavities in the head. Web the bones of the orbit develop via both endochondral and intramembranous ossification. Web there are 7 bones that comprise the orbit. The orbital roof is formed by the lesser wing of the sphenoid bone and the frontal bone.
Web there are seven orbital bones that make up this structure: Web seven bones form each orbit: The orbit is a pear shape, with the optic nerve at the stem, and holds approximately 30 cc volume. Web define bones 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. Maxilla, frontal bone, zygomatic bone, ethmoid bone, lacrimal bone, sphenoid bone, and palatine 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) The orbital roof is formed by the lesser wing of the sphenoid bone and the frontal bone. Pars orbitalis of the frontal bone lacrimal bone lamina papyracea of the ethmoid bone orbital process of the zygomatic bone orbital surface of the maxillary bone orbital process of the palatine bone greater and lesser wings and body of the sphenoid bone Web the orbit is the bony cavity in the skull that houses the globe of the eye (eyeball), the muscles that move the eye (the extraocular muscles), the lacrimal gland, and the blood vessels and nerves required to supply these structures. Web portions of six bones form its pyramidal walls:
