Chapter 16, Problem 4CAL
Summary Introduction
Introduction:
The eye is the sensitive part of a sense organ. It provides vision. It consists of photoreceptor cells such as rods and cones cells that are responsible for image formation in night and day.

Why is a retinal defect, such as retinitis pigmentosa, which causes tunnel vision, associated with night blindness?
a. Tunnel vision and night blindness are unrelated conditions.
b. The high density of rod photoreceptors in the fovea are unaffected in each condition.
c. The highest resolution cone photoreceptors are found exclusively in the outer regions of the retina.
d. The color-detecting cone photoreceptors have the greatest density in the outer regions of the retina.
e. The highly-sensitive rod photoreceptors are located in the outer regions of the retina.
Because fibers of the optic nerve that originate in the nasal halves of each retina cross over at the optic chiasma, each lateral geniculate receives input from a.both the right and left sides of the visual field of both eyes. b.the ipsilateral visual field of both eyes. c.the contralateral visual field of both eyes. d.the ipsilateral field of one eye and the contralateral field of the other eye.
At each level of the retina-geniculate-striate system, receptive fields in the foveal area are ___ than those at the periphery
Select one:
a. both smaller and rounder, for the reasons mentioned in each respective option
b. larger, since the fovea mediates low acuity vision
c. smaller, since the fovea mediates high acuity vision
d. rounder, the receptive fields in the periphery tend to be more square-shaped
