Which structure carries visual data from the retina to the brain?

• A. Optic chiasm.
• B. Lateral geniculate nucleus.
• C. Optic nerve.
• D. Ciliary body.

Answer: (C)

Visual data from the retina is carried along the axons of retinal ganglion cells, which bundle together to form the optic nerve. This nerve is the direct conduit that transmits signals from the eye toward the brain. After leaving the eye, some fibers cross at the optic chiasm and then proceed to relay centers like the lateral geniculate nucleus before reaching the visual cortex. The optic chiasm is a crossing point, the lateral geniculate nucleus is a relay station, and the ciliary body is involved in aqueous humor production and accommodation, not in transmitting retinal signals.
