GROSS ANATOMY

Detailed explanation-1: -The optic nerve is comprised of millions of nerve fibers that send visual messages to your brain to help you see. You have an optic nerve at the back of each eye that connects directly to your brain.

Detailed explanation-2: -The optic nerve consists of the myelinated axons of the retinal ganglion cells. As the axons come together to exit from the globe through the cribriform plate of the sclera, they gain a myelin sheath and form the optic nerve head.

Detailed explanation-3: -optic nerve, second cranial nerve, which carries sensory nerve impulses from the more than one million ganglion cells of the retina toward the visual centres in the brain.

Detailed explanation-4: -The optic nerve is composed of retinal ganglion cell axons and glia. Each human optic nerve contains between 770, 000 and 1.7 million nerve fibers, which are axons of the retinal ganglion cells of one retina.

Detailed explanation-5: -The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain.
