Textbook Question
Chapter 40.8, Problem 1TC
Retinal implants have boon developed to provide limited vision for people who have become blind due to retinitis pigmentosa or macular degeneration, in which the photoreceptors degenerate but many of the ganglion cells survive. Compare the structure of the retina and the cochlea. Based on what you know about cochlear implants, what would be the general guiding principles for designing a retinal implant?

Presbyopia is a condition in which a person's ability to adjust to changes in visual acuity diminishes or disappears entirely. Will she still require reading glasses after LASIK to correct her far vision? Explain.
Presbyopia is a condition in which a person loses part or all of their capacity to adapt to changes in visual acuity. Will she still need reading glasses after having LASIK to fix her far vision? Explain.

- 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_forwardWhat is meant by the statement Vision happens mainly in the brain?arrow_forwardLarry goes to the doctor complaining that he cant see the right side of the visual field with either eye.

- Figure 14.9 The basilar membrane is the thin membrane that extends from the central core of the cochlea to the edge. What is anchored to this membrane so that they can be activated by movement of the fluids within the cochlea? Figure 14.9 Cochlea and Organ of Corti LM × 412. (Micrograph provided by the Regents of University of Michigan Medical School © 2012)arrow_forwardJill is diagnosed with sensorineural deafness, a disorder in which sound waves are transmitted normally to the inner ear but they are not translated into neural signals that travel to the brain. Sometimes the cause is a problem with the auditory nerve, but in Jills case it has to do with a problem in the inner ear itself. Where in the inner ear is the disruption most likely to be located?arrow_forwardOccupational Hearing Loss Frequent exposure to loud noise of a particular pitch can cause loss of hair cells in the part of the cochlea that responds to that pitch. People who work with or around noisy machinery are at risk for such frequency-specific hearing loss. Taking precautions such as using ear plugs to reduce sound exposure is important. Noise-induced hearing loss can be prevented, but once it occurs it is irreversible because dead or damaged hair cells are not replaced. FIGURE 33.24 shows the threshold decibel levels at which sounds of different frequencies can be detected by an average 25-year-old carpenter, a 50-year-old carpenter, and a 50-year-old who has not been exposed to on-the-job noise. Sound frequencies are given in hertz (cycles per second), The more cycles per second, the higher the pitch. FIGURE 33.24 Effects of age aria occupational noise exposure. The graph shows the threshold hearing capacities fin decibels) for sounds of different frequencies (given in hertz) in a 25-year-okj carpenter (blue). a 50-year-old carpenter (red), arid a 50-year-ofd who did not have any on-the-job noise exposure (brown). 1.

- The inner ear is responsible for both hearing and balance. One of the diseases affecting the inner ear is Meniere's disease. Affected individuals often experience vertigo, among other symptoms. Vertigo is a sensation that the surrounding is spinning or swaying in the absence of any body movement. Which of the following rows correctly identifies the affected structure and process in individuals experiencing vertigo? Select one: a. Structure Process Semicircular canals Rotational equilibrium b. Structure Process Semicircular canals Gravitational equilibrium c. Structure Process Organ of Corti Gravitational equilibrium d.

This situation would result in _____________________. Sensorineural hearing impairment Increased movement of stereocilia towards the kinocilium Central hearing impairment Conductive hearing impairment Loss of endolymph in the cochlear duct Please consider providing a detailed and elaborate explanation of both correct options and incorrect options.arrow_forwardThe fluid that fills the cochlear duct, where the organ of Corti is located, is called____________. which of the following is a proprioceotor? Meissner's corpuscule muscle spindle Ruffini's corpuscule Merkel disc pain receptor Which of the following helps to explain why stimulation of cones results in more acute vision than stimulation of rods? 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_forward
- Which of the following statements about the contributions of rods and cones to vision is TRUE? A. The three types of cones (long, medium, short) are represented at roughly equal numbers B. Rods respond to light at ultra-violet wavelengths (>600nm) C. The relative density of cones is roughly even throughout the retina D. The greater sensitivity of rods in low light is explained by their larger number E. Several rods converge on a single bipolar cellarrow_forwardExplain the normal functioning of the eye to allow us to have visual acuity. What is meant by visual acuity? How does the eye adjust to facilitate this? Specifically, how do changes in near-point accommodation and astigmatism affect acuity? What is the problem with changes in near-point accommodation and astigmatism and why are they problematic? How can each of these be measured? Can these conditions be corrected? If so, how? Do these conditions change as we age?arrow_forwardWhy 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.arrow_forward
