Which nerve at the back of the eye receives the image from the retinal nerve fibers and transmits it to the brain?

• A. Retina
• B. Trigeminal nerve
• C. Ciliary nerve
• D. Optic nerve

Answer: (D)

Visual information travels from the retina through the optic nerve. The retina detects light and converts it into neural signals, and the axons of retinal ganglion cells bundle together to form the optic nerve, which exits the eye and carries those signals toward the brain for processing. The retina itself is the light-sensing layer, not the transmitting pathway. The trigeminal nerve handles facial sensation and motor functions, not vision, and the ciliary nerves supply the eye but do not carry image information to the brain. Thus, the nerve that matches the description is the optic nerve.
