WebThe visual pathway consists of the retina, optic nerves, optic chiasm, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex. The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon. Each photoreceptor has four major components. There is an outer segment, inner segment, nucleus, and a synaptic body (spherule). The outer segment is highly folded and contains the photosensitive chemicals necessary for initiating the visual impulse. The membrane of the outer segment is also highly folded into … See more The retinal pigmented epithelium is the most superficial (i.e. outermost) layer of the retina.
