Final answer:
The optic canals are located mostly medially within the eye socket, allowing for the passage of the optic nerve from the retina to the optic chiasm.
Step-by-step explanation:
When looking inside the eye socket, the optic canals are located mostly medially. The optic canal is situated at the posterior apex of the orbit, which allows for the passage of the optic nerve from the retina to the brain. The optic nerves from both sides enter the cranium through the respective optic canals and meet at the optic chiasm, which is located above the sella turcica of the sphenoid bone and inferior to the pituitary gland.
Lateral to the optic canal is the superior orbital fissure, an elongated and irregularly shaped structure that provides passage for arteries, sensory nerves, and nerves that supply the muscles involved in eye movements.
