Dissection of right orbit from a superior approach
Ciliary ganglion and connections; nerve supply to medial, inferior and lateral rectus muscles
The ophthalmic artery and its branches have been cut away to reveal the ciliary nerves (4) and ganglion (8) as well as the nerves which enter the rectus muscles. A distinct bulge occurs in each of the extraocular muscles just anterior to the point of entry of motor nerves into the muscle substance. A filament from the ophthalmic sympathetic plexus (10) joins the ciliary ganglion.
