Students have asked these similar questions
a) 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. I
c) Explain the difference in information that can be provided by a cochlear implant
consisting of a single electrode compared to a cochlear implant with many electrodes.
What type of neural code is provided in each case? What type of musical sounds could
be well…
Unilateral 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 epithelium
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?

- 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.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_forwardMr. Joseph arrived at the office with an ear infection. After the doctor carefully examined Mr. Joseph’s ears, he noticed that there was something in the left ear. He ordered his medical assistant to perform an ear irrigation on the patient. What instructions should the medical assistant give to the patient regarding the procedure? Mr. Joseph becomes increasingly anxious when he is informed that the procedure could be a little painful. How should the medical assistant respond to Mr. Joseph’s anxiety?arrow_forward
- a unitaleral lesion in which of the following structures is most likely to cause deafness in one ear? A) cochlear nuclei B) inferior collicus C) medial geniculate D) nucleus of the lemniscus E) superior olivary nucleusarrow_forwardWayne 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. Explain the pathway of sound.arrow_forwardOne 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_forward
- Blindsight is the condition in which someone with damage in the primary visual cortex reports that they cannot see an object, but can usually guess what that object is. This means that some visual representation must reach the frontal speech area. What non-thalamic pathway might do that? Question 8 options: A) The pathway through the suprachiasmatic nucleus B) The dorsal visual pathway C) The pathway through the superior colliculus D) The magnocelluar or M pathwayarrow_forwardA concussion is a mild traumatic brain injury. How might a concussion acutely affect hearing and balance? What are some potential long term side effects?arrow_forwardOtotoxic drugs are drugs that may damage the cochlea, auditory nerve and/or the vestibular system of the ear. The damage caused is usually temporary and symptoms improve once the patient stops taking the drug. However, in some patients, the damage is permanent. Damage to the cochlea is the most common problem associated with these drugs. The reason that hearing loss results when the cochlea is damaged is: Select one: a. The bones in the ear do not amplify or increase the sound vibrations. b. The eardrum cannot transmit vibrations from sound waves to the malleus. c. The Eustachian tube remains open. d. Hair cells within the damaged cochlea do not bend preventing the transmission of an electrical signal to the auditory nerve.arrow_forward
- After attending a Fourth of July fireworks extravaganza, Millie finds it difficult to hear normal conversation, and her ears keep “ringing.” What is causing her hearing problems?arrow_forwardthe sound of a vibrating tuning fork is perceived longer when the stern of the fork is placed against the mastoid process of the temporal bone than when the lines are placed near the patient's ear. This finding is compatible with damage to which of the following structures ? A) cochlea B) cochlear nucleus C) ossicles D) primary auditory cortex E) vestibulocochlear nervearrow_forwardGrandpa 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.arrow_forward
