(3) Retina. The inner layer of the wall of the eyeball is known as the retina,
retinal coat, or internal tunic. The actual photoreceptor elements are located in the
retina at the back and sides of the eyeball. These elements are the rods and cones.
They constitute the nervous portion of the retina. In the anterior part of the eyeball, the
retina continues as a nonnervous portion.
