Auditory nerve is eighth cranial nerve. It is called as vestibulocochlear nerve. It is the nerve to meant for hearing and balancing your body. The optic nerve is second cranial nerve. It carries sensory signals from your eye to the brain. It arises from the retina of the eye.
The junction between the retina and the optic nerve is the optic disc.
The natural blind spot (scotoma) is due to lack of receptors (rods or cones) where the optic nerve and blood vessels leave the eye. It is where the optic nerve leaves the retina not enter it. The optic disk or blind spot is where the optic nerve leaves the eye; you cannot use that field of vision because the optic nerve is there.
The optic disc
It may surprise some people but the optic nerve begins near your testicles.

Optic nerve is found in the eye which sends the nerve impulses from the eye to the brain. The auditory nerve is present in the ear and sends the nerve impulses from the ear to the brain. They both have the same functions though they're present in different places.
The junction between the retina and the optic nerve is the optic disc.
The Optic Nerve AKA Cranial Nerve II from eye to brain for sight and Craniel Nerves III (Oculomotor) and IV (Trochlear) for Eye movement.
The scaitic nerve is the longest and largest nerve.
The question is asking what three cranial nerves are purely sensory in their function. Some relevant terms here are olfactory, optic, and auditory or vestibucochlear or acoustic nerves. The only three cranial nerves that are pure sensory in function are cranial nerve #1 : the olfactory nerve (smell), cranial nerve #2 : the optic nerve (sight), and cranial nerve #8 : the auditory/vestibucochlear/acoustic nerve (hearing).
Occipital nerve. It is the second cranial nerve.
Point where optic nerve enters eyeball is the optic disc.
Optic nerve. Well, it connects the retina to the brain. The muscles of the eye also connect to the brain, but not through the optic nerve.
optic nerve
The optic nerve can be identified with the sense of sight.
your optic nerve attatches your eye and brain together
