Textbook Question
Chapter 43, Problem 12TYU
SCIENCE, 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.

A cochlear implant is very different from a hearing aid. Hearing aids amplify sound. A cochlear
implant is designed to compensate for damaged or nonfunctional parts of the inner ear.
Which of the following rows correctly identifies the structures of the ear that hearing aids and
cochlear implants replace?

Include a 5-10 sentence explanation of how the ear senses sound and relays that data to the brain to interpret auditory information. Some pieces to consider:
What path does the sound travel through the ear?
What structures do the waves interact with?
How does the signal travel to the brain?
Where in the brain is the data processed?
How does this sense change with age?
What could cause deafness in humans (there are at least two major ways this can happen)?
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 cells

- 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_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_forwardI need to differentiate the functions of parts of the ear. The vestibular apparatus, which has fluid and hairs in it--head position ex. car sickness, while reading in moving car; semicircular canals, which have hairs in it--balance and equilibrium ex. dizziness when riding a merry-go-round; and cochlea, which have cilia--hearing ex. hearing loss going to a concert.arrow_forward
- High intensity (loud) sounds can cause deafness because they are most damaging to the hair cells of the spiral organ of Corti tympanic membrane bones of the middle ear vestibular system What is the first brain structure to receive input from both ears and is important in locating the direction of sound? The superior olive Cochlear nuclei Inferior colliculus The primary auditory cortexarrow_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_forwardWhich of the following is TRUE for hearing? the organ of Corti sits on top of the vestibular membrane the stapes is connected to the round window the stereocilia of the hair cells of the organ of Corti are connected to the basilar membrane the cochlear duct is located between the vestibular and the basilar membranesarrow_forward
- In virtual reality which of the senses cannot currently be portrayed? Select one: O a. touch O b. hearing O c. smell O d. sightarrow_forwardThinking as a nurse, how can you best serve your patients who are in a state of illness that their senses may be affected? You write about hearing and the role it plays in our lives. Being a nurse, it is important to understand how the illness they are experiencing, and the medications may affect their different senses.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
- Which of the following are paired incorrectly? Group of answer choices cochlear duct — spiral organ semicircular canal — semicircular duct vestibule — otoliths cranial nerve — stereociliaarrow_forwardWhy does the actual Auditory response produced by stimuli have to be detected by electrodes located on the scalp and the earsarrow_forward(Bonus) Deafness and hearing loss are a widespread issue. According to WHO, currently more than 1.5 billion people (nearly 20% of the global population) live with hearing loss. From what you learned about our auditory system, briefly explain what would happen to hearing in each of the following scenarios. (a) the tectorial membrane can't hold its position and is pushing onto the auditory hair cells constantly. (b) the auditory hair cells near the base of the cochlea are damaged and dead. (c) the endolymph potassium concentration is lower than normal. (d) the perilymph potassium concentration is lower than normal.arrow_forward
