Define Binocular Fusion- combining of 2 images into one.

b. The lens focuses light onto the retina. Preservatives make the lens hard and opaque, but in living organisms the lens is clear and flexible. Based on the function of the lens, why are these features important?

Both the gustatory and olfactory system allow for the perception and identification of different chemical cues from the environment. Summarize the difference between these two systems with respect to coding. In other words, how does the neuronal activity of these systems provide a code that allows distinct chemicals to be represented?

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
