- 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_forwardSCIENCE, TECHNOLOGY, AND SOCIETY Cochlear implants bring hearing to many children who are born deaf. The prognosis is best when the device is implanted before the child is three years old (during the early years when language is developed). Many individuals in the deaf community (which consists of individuals born deaf or who are affected by deafness) who communicate with sign language oppose cochlear implants. They do not view the inability to hear as a disability. This perspective raises ethical questions for some families with children who are deaf. Argue for and against cochlear implants for very young children.arrow_forwardHow does the eye focus the light rays of an image? What do nearsighted and farsighted mean?arrow_forward
- Awareness of a stimulus is called a ________.arrow_forwardYour visual field is ______________. a. a specific, small area of the retina b. what you actually see c. the area where color vision occurs d. where the optic nerve startsarrow_forwardFigure 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_forward
- Which is the correct order of passing information of light stimuli among cells in the retina? ganglion cell bipolar cells → photoreceptor photoreceptor amacrine cells ganglion cell horizontal cell photoreceptor ganglion cell photoreceptor → bipolar cells → ganglion cellarrow_forwardIn order to see a dim star at night, it is better not to look directly at it. If you see it from the “corner of your eye” and then turn to look at it, it may disappear. Explain how this occurs. Also, you can staredirectly at an object in daylight and continue seeing it, despite the bleaching of photoreceptors. Explain how this is possible.arrow_forwardThere are a number of reasons for vision loss, both natural and unnatural. Use a blindfold to remove your sense of vision. how well your other senses adapt to the lack of visual input. How familiar is it? How does your perception of distance change?arrow_forward
- Classify statements about the eye as true or false. 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_forwardWhen a person blinks, the part of the brain that interprets visual stimulation is suppressed. The spontaneous act of blinking is controlled by the area of the brain that controls involuntary movements such as breathing and blood pressure. To determine whether the lack of light or the act of blinking causes the suppression, scientists had subjects close their eyes and then placed a bright flashing light in their mouth to stimulate the photoreceptors in the eyes through the palate. Visual stimulation was still suppressed. So the photoreceptors in the retina were not stimulated even though they were exposed to light. This study demonstrated that when a person blinks, it is the act of blinking and not the absence of light that causes the suppression of visual stimulation. In the diagram above, identify the part of the brain that is suppressed during blinking and the part of the brain that controls involuntary, spontaneous blinking. Select one: a. 3 and 8 b. 2 and 9 c. 5 and 6 d. 1…arrow_forwardHere 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.arrow_forward
