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.

Students have asked these similar questions
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.
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.
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.
