Hearing Physiology Quiz

What is the function of the auditory nerve?

• Regulates body temperature

• Transmits taste information from the tongue to the brain

• Carries sound information from the cochlea to the brain

• Controls the movement of the eyeball

How does the auditory nerve transmit signals to the brain?

• By releasing hormones into the bloodstream

• By using the sense of taste to communicate with the brain

• Action potentials in response to sound waves stimulating the hair cells in the cochlea

• By sending electrical signals through the olfactory nerve

Explain how sound waves are transmitted through the ear.

• Sound waves are transmitted through the ear by traveling through the ear canal and causing the eardrum to vibrate.

• Sound waves are transmitted through the ear by causing the earwax to vibrate and stimulate the auditory nerve.

• Sound waves are transmitted through the ear by passing through the nose and reaching the inner ear.

• Sound waves are transmitted through the ear by being converted into electrical signals by the cochlea.

What role does the cochlear hair cells play in hearing?

• Regulating the balance of fluids in the inner ear

• Producing mucus to protect the ear canal

• Filtering out harmful bacteria from the ear canal

• Converting sound vibrations into electrical signals

How do cochlear hair cells convert sound vibrations into electrical signals?

• Digestion

• Photosynthesis

• Mechanotransduction

• Chemical reaction

Describe the process of auditory processing in the brain.

• Reception and interpretation of visual signals from the eyes, transmitted to the visual cortex for processing

• Reception and interpretation of sound signals from the ears, transmitted to the auditory cortex for processing

• Reception and interpretation of touch signals from the skin, transmitted to the somatosensory cortex for processing

• Reception and interpretation of taste signals from the tongue, transmitted to the gustatory cortex for processing

What part of the brain is responsible for interpreting and making sense of the auditory signals?

• Auditory cortex

• Prefrontal cortex

• Visual cortex

• Motor cortex

What are some common causes of hearing loss?

• Using a smartphone too often

• Not wearing a hat in cold weather

• Eating too much sugar

• Aging, exposure to loud noises, genetics, ear infections, and certain medications
