What is the term for the paired nerve that transmits visual information from the retina to the brain?

Explanation:
Visual information travels from the retina to the brain through a paired nerve that is the second cranial nerve, the optic nerve. It’s a sensory bundle made of retinal ganglion cell axons, leaving each eye at the optic disc and passing through the optic canal. From there, signals cross at the optic chiasm (with some fibers crossing to the other side) and continue as the optic tract to the thalamus, then to the visual cortex for processing. The other structures listed aren’t nerves: retinal pigment epithelium is a nourishing layer, the vitreous is the gel inside the eye, and the aqueous humor is the fluid in the eye’s chambers.
