Textbook Question
Chapter 14, Problem 3CT
Jill 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 Jill’s 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?

Grandpa can't ever seem to hear what his little granddaughters say. He also can't hear that high-pitched whine in the Subaru engine that everyone else seems to hear. You suspect that grandpa
has too much ear wax built up in his external auditory canal, and therefore has developed conduction deafness
has damage to the vestibulocochlear nerve
has damaged either the utricle or the saccule, though it will be hard to tell which one without further testing
has damaged the hair cells closest to the oval window
has "selective" hearing loss, because the granddaughters are always trying to get him to play with them when he's tired, and he doesn't want to work on that darned car anymore either.
Milo and Garfield are two friends who have acquired hearing loss, but the cause of hearing loss in Milo is different from that in Garfield. Milo has a conductive hearing loss. He can hear, but not clearly and loudly. The doctor has told Milo that calcium has built up on the bones in his middle ear interfering with their movements. Garfield has neural hearing loss. The doctor has told Garfield that he cannot hear because the auditory nerve cannot transmit electrical impulses from receptors in his inner ear to his brain. By completing the following tasks, help Milo and Garfield understand how their ear works and why they have difficulty hearing sounds.
E. Draw and label a diagram showing the position of the bones in the middle ear.
F. Explain the function of the bonesinconducting sound.
G. Draw and label a diagram showing the inner ear, the position of receptors and the auditory nerve.
Presbycusis is an age-related hearing loss affecting individuals over the age of 65. Many affected
individuals have difficulty understanding words because, although they may be able to hear the
sound, they are unable to distinguish the exact words. This hearing loss is most noticeable at
higher frequencies.
Which of the following statements correctly describes an individual suffering from presbycusis?
Select one:
a. Individuals with presbycusis have damaged hair cells at the base of the cochlea, which is
closest to the oval window.
b. Increasing the volume of higher frequency sound allows individuals affected with
presbycusis to hear better.
O c. Individuals with presbycusis have damaged hair cells at the apex of the cochlea, which is
farthest from to the oval window.
Od. Decreasing the amplitude of lower frequency sound allows individuals affected with
presbycusis to hear better.

- One of the mechanisms that the auditory system uses to localize sound is referred to as interaural time difference (ITD). Where in the brain does this takes place and explain how this mechanism would enable you to localize a sound coming from your left side.arrow_forwardAfter chronic ear infections as a kid, my husband experienced what is known as otosclerosis. Basically, his ear bones started to fuse together. This resulted in hearing loss. What type of hearing loss is this, and how can it be treated?arrow_forwardUnilateral Cerebral strokes can cause deficits in motor control, somatic sensation and vision. However, they do not cause deficits in hearing. The explanation for this is: Auditory information does not reach the cortex Auditory information only goes to one hemisphere. Auditory information goes to both hemispheres How are the outer segments of photoreceptors positioned? between bipolar cells and horizontal cells in the outermost layer of the retina in the ganglion cell layer farthest from the pigment epitheliumarrow_forward
- When Maddie’s physician examines her ear, he explains to her parents that she has a perforated eardrum. Which of the following statements is NOT true? Maddie is at higher risk for ear infections due to the perforation. Maddie’s eardrum will likely heal on its own and she will not need surgery. A perforated “eardrum” means that there is a tear or hole in Maddie’s tympanic membrane. Maddie has sensorineural hearing loss due to the perforated eardrum.arrow_forwardWhich of the following statements concerning the inner ear is TRUE? Question 3 options: a) The bony labyrinth within the tempoal bone contains spaces for the semicircular canals and the cochlea. b) The fibers of the cochlear nerve are attached to hair cells in the semicircular canals to carry information about movements of the head. c) The frequency of sound waves as defined by their wavelengths are perceived as pitch and are measured in decibels (dB). d) The saccule and utricle are critical sensory receptors for interpreting language, distinct from other sounds.arrow_forwarda) Consider a patient who has been exposed to an ototoxic drug that has caused the death of the outer hair cells in the cochlea but has left the inner hair cells unaffected. What sort of hearing loss is the person likely to experience and what sort of hearing device could assist them? Explain the reasons for your answer based upon how the inner ear functions. b) Consider a person who has a partial loss of myelin in their auditory nerve. What effect would the loss of myelin have upon the ability of this person to perceive speech and would either a hearing aid or cochlear implant provide any benefit to their hearing ability? Explain the reasons for your answer based upon how the inner ear and auditory pathway function.

- Wayne is a 75-year-old retired teacher who comes to the physician’s office feeling quite upset. He tells Rebecca, the licensed practical nurse, that he does not know what is happening to him. When people speak to him their speech seems garbled, and lately he is having difficulty reading. After an examination, the physician tells him he has a conductive hearing loss because of accumulated cerumen. What is the role of an audiologist?arrow_forwardA 33-year-old, right-handed roller derby skater comes to you complaining of periodic attacks of tinnitus ("ringing" or "buzzing") in her left ear and vertigo (the sensation that she and her surroundings are moving relative to one another, when she is standing or sitting still). She says these attacks have been becoming more frequent over the past year or so and that now, between attacks, she feels as though she can't hear as well with her left ear as she can with her right. Your examination reveals that the auditory threshold is indeed elevated in her left ear, whether you use air conduction or bone conduction. You also notice that touching either cornea with a wisp of cotton causes her right eye to blink briskly and her left eye to blink somewhat sluggishly. Then you notice that she seems to have a somewhat asymmetrical smile: The right side of her face moves more than the left. Which of the following best accounts for this patient's list of problems? Damage to the left…arrow_forwardMeniere's disease is a disorder of the inner ear that may be due to an increase in the amount of endolymph. What would be some symptoms of this disease? Since the disease affects the inner ear and endolymph, it would probably limit the ability to equalize pressure and cause pain. Since the disease affects the inner ear, it would probably cause nausea and migraines. Since the disease affects the inner ear, it would probably cause issues with taste. Since the disease affects the inner ear, it would probably cause issues with balance and a sensation of vertigo. It could also cause hearing loss if it affected the cochlea.arrow_forward
- More than 1.1 billion young adults are at risk for hearing loss according to World Health Organization (WHO, 2015). The primary reason is increasing use of personal audio devices with headphones or earphones. Hearing loss is of two main types: conduction deafness and perception deafness. Young adults are more likely to experience perception or nerve deafness. Which of the following parts of the ear is not involved in nerve deafness? Select one: a. Organ of Corti b. Semicircular canal C. Auditory nerve and basilar membrane d. Sensory neurons and hair cellsarrow_forwardYour friend had a severe infection in the cochlea, which caused deafness. The scarring from the infection prevents movement of the basilar membrane of the organ of Corti. In response to a sound, you would predict that: The tympanic membrane would not vibrate The tympanic membrane would vibrate but the three bones in the middle ear would not move The three bones in the middle ear would move, but the cochlear fluid would not have any waves The cochlear fluid would have waves, but the hair cells would not bend The hair cells would bend, but no receptor potential would be createdarrow_forwardWayne is a 75-year-old retired teacher who comes to the physician’s office feeling quite upset.
