Maxilla and sphenoid complex. a) Rendered 3-D reconstruction of the maxillary complex and eye, left upper view. There is a single eye within the orbit containing two retinae. A single optic nerve leaves the orbit through a central optic canal. b) Rendered 3-D reconstruction of the sphenoid complex with the pterygoid, palatal bones, and sphenoid bone in the right view. The paired retinae and the optic nerve are also shown.
