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.
Occupational Hearing Loss Frequent exposure to loud noise of a particular pitch can cause loss of hair cells in the part of the cochlea that responds to that pitch. People who work with or around noisy machinery are at risk for such frequency-specific hearing loss. Taking precautions such as using ear plugs to reduce sound exposure is important. Noise-induced hearing loss can be prevented, but once it occurs it is irreversible because dead or damaged hair cells are not replaced. FIGURE 33.24 shows the threshold decibel levels at which sounds of different frequencies can be detected by an average 25-year-old carpenter, a 50-year-old carpenter, and a 50-year-old who has not been exposed to on-the-job noise. Sound frequencies are given in hertz (cycles per second). The more cycles per second, the higher the pitch. FIGURE 33.24 Effects of age aria occupational noise exposure. The graph shows the threshold hearing capacities fin decibels) for sounds of different frequencies (given in hertz) in a 25-year-okj carpenter (blue), a 50-year-old carpenter (red), and a 50-year-otd who did not have any on-the-job noise exposure (brown). 3. Which of the three people had the best hearing in the range of 4,000 to 6,000 hertz? Which had the worst?

How loud did a 1,000-hertz sound have to be for the 50-year-old carpenter to detect it?

Based on these data, would you conclude that the hearing decline in the 50-year-old carpenter was caused by age or by job-related noise exposure?
Figure 36.18 Which of the following statements about the human eye is false? Rods detect color, while cones detect only shades of gray. When light enters the retina, it passes the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye. The iris adjusts the amount of light coming into the eye. The cornea is a protective layer on the front of the eye.
Sort the following in the order required for activation of cochlea hair cells. Drag and drop options into correct order and submit. For keyboard navigation. SHOW MORE V Sound waves enter the ear. A standing wave is formed inside the cochlea. The standing wave causes the activation of hair cells. The oval window of the cochlea vibrates. Fluid within the cochlea vibrates. Tympanic membrane vibrates. Ossicles vibrate. II II II
The role of the ossicles is to of vibrations Decrease the intensity Increase the strenght O Change the wavelengths The fovea is the part of the retina that contains photoreceptors called: Cones Amacrine cells Rods Ganglion cells

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? Select one: а. Device Cochlear Implant Hearing Aid Structure of the Ear hair cells tympanum and ossicles Intended to Replace b. Device Cochlear Implant Hearing Aid Structure of the Ear basilar membrane tympanum Intended to Replace С. Device Cochlear Implant Hearing Aid Structure of the Ear ossicles organ of Corti Intended to Replace d. Device Cochlear Implant Hearing Aid Structure of the Ear tympanum ossicles Intended to Replace
The function of structure 4, the round window, is to _________. bulge outward to give the fluid of the inner ear somewhere to go when the stapes pushes inward transmit sound from the ear ossicles of the middle ear to the hair cells of the inner ear amplify the sound wave as it is transmitted from the typanic membrane to the ear ossicles prevent fluid in the middle ear from entering the inner ear while allowing sound transmission
I 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.
Figure 1 shows the internal structure of the ear. Label and Describe in details how A-G structure works collectively in the hearing mechanism.
