Chapter 40, Problem 3FIB
Summary Introduction
Introduction:
The eye is the sensitive part of the sense organs that provide vision. It consists of photoreceptor cells, such as rods and cones cells, that are responsible for image formation during both night and day. The various parts of eyes are aqueous humor, vitreous humor, retina, iris, and pupil, and so on.

- Figure 36.18 Which of the following statements about the human eye is false? Rods detect color, while cones detect only shades of gray. When light enters the retina, it passes the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye. The iris adjusts the amount of light coming into the eye. The cornea is a protective layer on the front of the eye.arrow_forwardWhat is meant by the statement Vision happens mainly in the brain?arrow_forwardAs you read the question, light enters your eye, is focused, detected, and then changed into electrical impulses that are sent to your brain. Starting with the cornea and ending with the optic nerve, list all the structures of the eye that light passes through (in order) and describe their functions.arrow_forward

True The iris regulates the amount of light that enters the eye. The cornea is a transparent covering over the eye. The fovea is the part of the eye where you have the sharpest, most distinct vision. The image formed in the eye is upright. False Adjustments in focus are collectively called accommodation and are made by the ciliary muscle. The fovea is the opening through which light enters the eye. The image seen by the eye should be focused on the pupil Information leaves the eye through the ciliary muscle.arrow_forwardCones are the eye’s receptor cells that are especiallysensitive to ________light and are responsible for our____________vision.arrow_forward
