Which canal transmits the optic nerve and ophthalmic artery?

The main idea is that the optic nerve and the ophthalmic artery travel together through the optic canal. This small passage in the sphenoid bone serves as the conduit from the orbit into the cranial cavity for CN II and the ophthalmic artery. Other openings around this area have different contents: the superior orbital fissure transmits nerves for eye movement and sensation to the forehead (not CN II); the foramen rotundum carries the maxillary nerve (V2); and the foramen lacerum is largely cartilage-filled and does not transmit the optic nerve or ophthalmic artery in life. So, the canal that transmits both the optic nerve and ophthalmic artery is the optic canal.
