Vascular nutrient layer of outer retina (including retinal pigment epithelium and rods and cones) sclera A rod cell possesses a distinct structure, comprising an outer segment, an inner segment, a cell body containing the nucleus, and a synaptic terminal Superficial portion, called episclera, has rich vascular network
Bilirubin accumulates in episclera to stain sclera yellow (icterus). Rod cells, or rods, are photoreceptor cells in the retina of the eye that can function in less intense light than can the other type of photoreceptor, cone cells Retina is a complex tissue comprising various cell types.
An outer segment, an inner segment, the cell body, and the synaptic region The outer segment contains the phototransduction apparatus. There are significantly more rod cells than cone cells in the retina, with the rods located in the outer areas of the retina and the cones being in the centre of the retina, known as the macula. This article describes the organization, types, and functions of photoreceptors (rods and cones) in the retina
Rods are unresolved in this image, but are likely to be nestled in the dark gaps between cones. Cross section of the retina Rods are visible at far right
