The sphenoid and ethmoid bones form mostly via endochondral ossification while the frontal bone is formed by intramembranous ossification. Frontal, sphenoid, ethmoid four facial bones: 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 the orbit, which protects, supports, and maximizes the function of the eye, is shaped like a quadrilateral pyramid, with its base in plane with the orbital rim. Formed by the lesser wing of the sphenoid and the frontal bone. In this article, we shall look at the borders, contents and clinical correlations of. Web the face is attached anteriorly and consists of two unpaired bones, the vomer and mandibular bones, and six paired bones, the nasal, maxillary, zygomatic, palatine, lacrimal, and inferior turbinate bones. Web let's look at how these seven orbital bones join to form different parts of the eye socket (orbit): Frontal, sphenoid, maxillary, zygomatic, palatine, ethmoid, and lacrimal.

There are 7 bones that form the orbit: Bones, muscles, arteries, veins and nerves. 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.
