The Optic Nerve Passes Through Which Structure

Question

The optic nerve passes through which structure?
A) superior orbital fissure
B) inferior orbital fissure
C) optic canal
D) internal optic meatus
E) external acoustic meatus

Accepted Answer

The optic nerve passes through the optic canal, which is located in the sphenoid bone. The superior orbital fissure and inferior orbital fissure are also located in the sphenoid bone but do not contain the optic nerve. The internal auditory meatus is located in the temporal bone and contains the vestibulocochlear nerve, while the external auditory meatus is located in the temporal bone and is the part of the ear that leads to the eardrum.
