The optic nerve is associated with which sense?

• A. Vision
• B. Smell
• C. Hearing
• D. Taste

Answer: (A)

The optic nerve is the sensory pathway for vision. It carries signals from the retina, where light is turned into neural impulses by photoreceptors, along retinal ganglion cell axons that form the optic nerve. Those signals travel to the brain, primarily to the visual cortex, where sight is perceived. Because this nerve is dedicated to conveying visual information, it is not involved in smell, hearing, or taste, which use other neural pathways. So the optic nerve is associated with vision.
