Question
Chapter 34, Problem 1TY
Summary Introduction
Introduction:
Hair cells are sensory receptors of hearing system and vestibular system in the ears of all vertebrates. Hair cells are found within the organ of corti on the basilar membrane in the cochlea of the ear.
Expert Solution & Answer
Answer to Problem 1TY
The correct answer is option (b) hearing in mammals.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) hearing in mammals. The hair cell detects sounds and head motion to process the hearing and balance control. Hearing loss is usually caused by the damage of hair cells in the cochlea. Hair cells are mechanosensitive cells that are found in vertebrates, and not in invertebrates. So, the correct answer is option (b).
Explanation for incorrect answer:
Option (a) balance in vertebrates and invertebrates. Hair cells are involved in balance control but they are found only in vertebrate animals, and not in invertebrates. So, this is an incorrect option.
Option (c) vision in animals with compound eyes. Hair cells are involved in the process of hearing and balance control, not in vision. While vision in animals is performed by photoreceptors (rod cells and cone cells). So, this is an incorrect option.
Option (d) heat sensing in pit vipers. Hair cells are involved in the process of hearing and balance control in vertebrates. While pit vipers perform heat-sensing by the pit organs. So, this is also an incorrect option.
Option (e) both option (a) and (b). Option (a) is already incorrect. So, this is an incorrect option.

- 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.
