Human Skull - optic canals (of sphenoid bone)

The probe is pointing through an optic canal located in the sphenoid bone of the skull. More specifically, the optic canals are found directly inferior to the small projections (clinoid processes) coming off of the lesser wings, or directly superior and slightly anterior to the sella turcica. The optic canal transmits the optic nerve and ophthalmic artery into the orbital cavity ("orbit") or eye socket.
