- Which of the following statements are true of the physiology of vision? (Read carefully and select all the correct statements.) A. Cones are the receptors for color. B. The lens adjusts for distant vision, and the cornea adjusts for near vision. C. The optic nerve is formed by the ganglion neurons of the choroid layer. D. For near vision, the pupils dilate and the eyes converge. E. The optic chiasma is a crossing of optic nerve fibers that contributes to binocular vision. F. The visual areas are in the occipital lobes of the cerebrum. G. The area of the retina for the best color vision is the optic disc. H. Rods are most numerous at the periphery of the retina.arrow_forwardWhich of the following statements explains why vision is less sharp in dim light than in bright light?a. Cones are more responsive in dim light.b. There are more rods than cones in the eye.c. Many rods converge on a single ganglion.d.

- The lens of the eye a. may turn opaque and cloudy with age b. may be removed and replaced with an artifical lens in a patient with cataracts c. may degenerate and cause glaucoma d. A, B, C e. A and Barrow_forwardWhich of the following are correct? Which one or more? a. Auditory fatigue is the increase in threshold after exposure to a loud sound. Auditory adaptation is a reduction in response of the auditory receptors to a sound over time followed by a steady state. b. The change in auditory thresholds is independent of the intensity, but dependent on the duration of the loud sound. c. Exposure to loud sounds is unable to damage the hair cells in the inner ear and therefore cannot lead to a permanent threshold shift. d.
