Question
Chapter 10, Problem 21RQ
Summary Introduction
Introduction: Human beings gave a pair of eyes that receive the sensation of vision. The eye contains photoreceptors that are activated by the presence of absences of light. There are two types of photoreceptors that allow the vision during day and night time.

Visual acuity is greatest when a ganglion cell has ____________________(many or few) photoreceptors in its visual field
The retinal uses __________________________(absolute light intensity or contrast) to identify objects in the environment. How is this accomplished?
Explain how binocular vision allows us t see things in 3 dimensions.
Here you see an astigmatism illustration. Please explain why astigmatisms cause blurred vision in the context of our sense of sight. Please do not merely say “The light rays do not hit the focal point”. Please explain why that matters for the sense of sight.

- Figure 36.14 Cochlear implants can restore hearing in people who have a nonfunctional cochlea The implant consists of a microphone that picks up sound. A speech processor selects sounds in the range of human speech, and a transmitter converts these sounds to electrical impulses, which are then sent to the auditory nerve. Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.arrow_forwardFigure 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_forwardIn order to see a dim star at night, it is better not to look directly at it.

Cones are more sensitive to color than rods are Cones require abundant light in order to be stimulated Rods are very sensitive, and can be stimulated even in very low light, so the signals all bleed together Cones have an almost 1:1 relationship with their axon pathways back to the cortex Cones are highly concentrated in the fovea, and rods are notarrow_forwardNegative images are not explained by the ___________ of color vision.
