The Optic Nerve

Question

The optic nerve
A) carries electrical signals from the retina to the primary visual cortex.
B) is CN III.
C) is the sensory arm of the corneal reflex.
D) is mixed.

Accepted Answer

The optic nerve carries electrical signals from the retina to the primary visual cortex, which is responsible for processing visual information. The other choices are incorrect as the optic nerve is not CN III, which is the oculomotor nerve; it is not part of the corneal reflex, which is mediated by CN V (trigeminal nerve); and it is not a mixed nerve, as it only carries sensory information related to vision.
