Which nerve transmits visual information from the retina?

Which nerve transmits visual information from the retina?

• A. Olfactory nerve
• B. Optic nerve
• C. Trigeminal nerve
• D. Vestibulocochlear nerve

Answer: (B)

Visual information from the retina is carried by the optic nerve. This nerve, the second cranial nerve, transmits afferent signals from retinal ganglion cells toward the brain. After exiting the eye at the optic disc, it travels through the optic canal and partially crosses at the optic chiasm before continuing as the optic tract to the thalamus and then to the occipital cortex for interpretation. The other nerves listed have different roles: the olfactory nerve handles smell, the trigeminal nerve mediates facial sensation and motor control for chewing, and the vestibulocochlear nerve handles hearing and balance.
