Successful hearing depends on the proper functioning of three organs.
Step by step
Solved in 2 steps
- 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.Match each of the following terms with the appropriate description. _____ somatic senses (general senses)a.produced by strong stimulation _____ special sensesb.endings of sensory neurons or specialized cells next to them _____ variations in stimulus intensity _____ action potentialc.taste, smell, hearing, balance, and vision _____ sensory receptord.frequency and number of action potentials e.touch, pressure, temperature, pain, and muscle senseAsap Successful hearing depends on the proper functioning of three organs . Explain
- Discuss the basic difference between determining the location of a sound source in the brain and determining the location of the visual object in the brain. Please include references.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…describe pitch for hearing (easy and simple)
- Explain the mechanism of hearing only in the form of a flowchart. Quick answer needed. no need for explanation.If Maddie’s hearing loss persists after her perforation is healed, which of the following scenarios is likely? Maddie suffered sensorineural AND conductive hearing loss from the head injury in the pool. Maddie will likely lose hearing in her left ear, too, but less severely. Her hearing loss is genetic and will be passed on to her future children. Maddie will continue to lose hearing bilaterally as she ages.
