Which cranial nerve is responsible for vision?

Explanation:
Vision relies on a sensory cranial nerve that transmits visual signals from the retina to the brain. This is the optic nerve, cranial nerve II. It carries afferent information from the photoreceptors in the retina, travels through the optic canal, and, after partial crossing at the optic chiasm, sends impulses to the visual cortex in the occipital lobe for interpretation. The olfactory nerve handles smell, while the oculomotor and trochlear nerves control most eye movements (and some pupil functions) rather than carrying visual information itself. So the nerve responsible for vision is the optic nerve.
