Chapter 45, Problem 3Q
Summary Introduction
To review:
The difference between the basilar membrane in the cochlea of a bat and the basilar membrane of a human ear.
Given:
The sound pulses that are made by the bats and moths have a frequency of around 50 kHz (kilohertz) or in other words, 50,000 cycles per second. The upper limit of sound frequency, which a human ear can detect, is around 20,000 Hz (hertz).
Introduction:
The basilar membrane, which is present in the cochlea (part of the inner ear), is a structure which separates two different tubes filled with liquid. These two fluid containing tubes are called scala tympani and scala media. The basilar membrane is lined with hair cells, which act active as auditory receptors, which are responsible for the detection of sound and thus are important for hearing.

Students have asked these similar questions
Which of the following does NOT play a role in the detection of sound?
Group of answer choices
stimulation of hair cells in the spiral organ
vibration of the tympanic membrane
vibration of the basilar membrane
vibration of ossicles against the round window
The volley theory of auditory information transfer is:
When hair cells follow the waveform of stimulating sinusoids > 3 kHz
Dependent on the organization of the basilar membrane
Responsive with an AC component to low frequency tones
An extraordinarily slow process
Which of the following statements concerning photoreceptors is not correct ?
cones produce colored images whereas rhods don't
cones contain rhodopsin
cones are less sensitive to light
cones produce clear images
One 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.

- 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_forwardFor vertebrate photoreception, define: (a) photopigment; (b) photoreceptor; and (c) receptive field.arrow_forwardOccupational 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 site and distribution of the photoreceptors is the same as in humans. Question: What might be true for Zerons vision? The images formed in the dark are sharper than those formed in light The central parts of their visual field aren't as sharp as the peripheral parts of their visual fields. They are better at forming color contrasts in images They have poor differentiation between black and whitearrow_forwardHere you see an astigmatism illustration.
