Question

Eyebrow Eyelashes Figure 8-2 10. In the following table circle the correct word under the vertical headings that describes events occurring within the eye during close and distant vision. Vision | Ciliary muscle | Lens convexity | Degree of light refraction 1. Distant | Relaxed | Contracted | Increased | Decreased | Increased | Decreased 2. Close | Relaxed | Contracted | Increased | Decreased | Increased | Decreased 11. Name in sequence the neural elements of the visual pathway, beginning with the retina and ending with the optic cortex. Retina —> ___ —> _ —> _ Synapse in thalamus —> ___ —> Optic cortex 12. Complete the following statements by inserting your responses in the answer blanks. There are (1) varieties of cones. One type responds most vigorously to (2) light, another to (3) light, and still another to (4) light. The ability to see intermediate colors such as purple results from the fact that more than one cone type is being stimulated (5). Lack of all color receptors results in (6). Because this condition is sex linked, it occurs more commonly in (7). Black and white, or dim light, vision is a function of the (8).
