CRANIAL NERVES ------- Optic nerve (CN 2), sensory only. Receptors in the retina (rods & cones) synapse with bipolar cells, which synapse with ganglion cells. Ganglion cells form optic nerve.

Stem Cell Treatment Successfully Restores Sight | IFLScience. I wish they would try to inject stem cells into damaged optic nerves. Though, I'm not sure how intolerant the optic nerve would be to foreign antigens. Since it is legal to use embryonic stem cells now, people are getting their eye sight back.

✿⊱╮Retina close up cross section | The retina is the innermost layer of the eye and is composed of several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells, rods and cones. Light energy creates an image of the visual world on the retina, triggering nerve impulses that are sent to the visual centers of the brain through the optic nerve.

Extra-ocular muscles that participate in the vestibular ocular reflex (VOR). These muscles are paired with the semi-circular canals of the vestibular system to allow the eyes to maintain stabilized during slow movements of the head.
