Optic Nerve
The optic nerve transmits electrical
impulses from the retina
to the brain. It connects to the back of the eye near the
macula. When examining the back of the eye, a portion of the
optic nerve called the optic disc can be seen.
The retina's sensory receptor cells of
retina are absent from the optic nerve. Because of this, everyone has a
normal blind spot. This is not normally noticeable because the vision of
both eyes overlaps.
