WebDec 19, 2024 · The visual system consists of two primary parallel pathways: an optic pathway and a pupillary reflex pathway. Optic Pathway The optic pathway begins in the retina, which is a complex structure made up of ten different layers. Each layer serves a distinct function. 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 … See more The retinal pigmented epithelium is the most superficial (i.e. outermost) layer of the retina.
