WebHuh, like everyone else said, this video didn't illustrate the rods and cones quite right. Cones (and rods) are bipolar neurons. From posterior to anterior a cone goes：outer segment (the "conical" part which contains the photosensitive chemicals, aka the disc), inner segment, cell body (the part that contains the nucleus), axon, axon terminals (aka synaptic ending). WebFigure 3.2 shows schematics of a mammalian rod and a cone photoreceptor. Light imaged by the cornea and lens is shown entering the receptors through the inner segments.The light passes into the outer segment which contain light absorbing photopigments.As light passes from the inner to the outer segment of the photoreceptor, it will either be absorbed by one …
