Which of the following is a common cause of sensorineural hearing loss?
Fluid trapped in the middle ear
Aging
Ruptured tympanic membrane
Cerumen build up
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
The connection between hair cells and cranial nerve VIII is made by:
direct contact
release of neurotransmitters
electrical synapses
transduction
The cochlear apex is:
Not associated with a topographical mapping of frequency
Where the helicotrema is located
Most tuned for high frequencies
Nearest to the oval window when the cochlea is uncoiled
Displacement of the hair bundle toward the shortest stereocilia:

- 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 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_forwardWhich of the special senses is based on the following events? Membrane vibrations cause fluid movements, which lead to bending of mechanoreceptors and firing of action potentials. a. taste b. smell c. hearing d. visionarrow_forwardFigure 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_forward
- Which structure is highlighted? Multiple Choice pons olfactory bulb optic chiasm cerebellum medulla oblongataarrow_forwardConduction deafness would most likely be caused by damage to the:a. cochlear nerveb. malleus, incus, and/or stapesc. hair cells in the cochlead. vestibular apparatusarrow_forwardPresbycusis 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_forward

- Your 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_forwardThink about this medical scenario and answer why physicians may disregard this common side effect of ototoxic medications. A common side effect of antineoplastic, chemotherapeutic treatment for cancer is ototoxicity, development of sensorineural hearing loss, and tinnitus. Why do oncologists (physicians who treat cancer) sometimes disregard these side effects?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
