Recall that the eye is composed of three layers or "tunics" — the fibrous, vascular, and nervous layers — which enclose two cavities that are separated from each other by the lens. Review the components of these three layers by matching each description with the appropriate letter in the figure below: 1. Fluid in the anterior portion of the eye that provides nutrients to the lens and cornea 2. The "whites" of the eye 3. Area of the retina that lacks photoreceptors 4. Contains smooth muscle that controls the shape of the lens 5. Nutritive (nourishing) layer of the eye 6. Layer containing rods and cones 7. Gel-like substance that helps support the eyeball 8. Pigmented smooth muscles that control pupil size 9. Most anterior component of the fibrous layer — your "window to the world" 10. Structure that changes shape to bend light toward rods and cones
