In anatomical terms, what is the orbit?

In anatomical terms, the orbit is the eye socket—a bony cavity in the skull that houses the eyeball and its supporting structures, including the extraocular muscles, nerves, blood vessels, fat, and the lacrimal apparatus. It’s formed by several skull bones and has openings that connect to the cranial cavity. The other descriptions refer to different parts: the mucous membrane lining the eyelids and the eyeball is the conjunctiva; the white part of the eye is the sclera; the clear tissue at the front of the eye is the cornea.
