GENERAL HISTOLOGY

Detailed explanation-1: -The optic nerve connects the eye to the brain. Our sight relies on the optic nerve transmitting information on shape, colour and pattern from the back of the eye (retina) to the brain’s visual centres.

Detailed explanation-2: -The optic nerve is critical to your vision. It’s an extension of your central nervous system, which includes your brain and spine. The optic nerve transmits electrical impulses from your eyes to your brain. Your brain processes this sensory information so that you can see.

Detailed explanation-3: -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-4: -In the brain, the optic nerve transmits vision signals to the lateral geniculate nucleus (LGN), where visual information is relayed to the visual cortex of the brain that converts the image impulses into objects that we see.

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. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs.
