The anatomy of the orbit includes, the bony cavities that contain the globes, extraocular muscles, nerves, fat, and blood vessels. The orbital walls are perforated by several important apertures. The periorbita, also called the orbital periosteum or orbital fascia, covers the bones of the orbit. This dense connective tissue membrane serves as an attachment site for muscles, tendons, and ligaments and is a support structure for the blood supply to the orbital bones. The extraocular muscles are responsible for the movement of the eye and for synchronous movements of the eyelids. The eyelids form a soft-tissue protection to the globe and the anterior entrance to the orbit. The orbital septum separates the bony orbit from the eyelid and represents the anterior most orbital structure. |
