a) a white, tough outer sclera or fibrous tunic, specialized anteriorly as the transparent cornea (the cornea may be milky because of preservation); b) the choroid coat , a dark, heavily pigmented layer which is specialized anteriorly to form the iris and the ciliary body; and c) the innermost membranous gray retina , which contains the light sensitive cells. At the front of the eyeball, near the lens, the choroid coat forms a thickened, ring-shaped radially striated muscular area, the ciliary body , that curves to enclose the lens. The ciliary body is the

Unformatted text preview: point of attachment of the suspensory ligament During the process of accommodation, contraction of the muscle fibers in the ciliary body reduces the pull on the suspensory ligaments and thus on the lens, thereby allowing the naturally elastic lens to assume a more rounded shape, which brings near objects into better focus. Examine the rear half of the eye more carefully; note the pale, loose retina attached to the wall of the eye at the optic disc. It is also called the blind spot because there are no rods or cones in this area. Beneath the rear portion of the retina, the choroid layer is covered by a shiny greenish-blue material. This is the tapetum , a reflecting area that sends incident light back through the retina, thus making efficient use of the light....
