Which of the following describes what happens if you trace an auditory stimulus from the time it first reaches the ear until it arrives at the brain?
A)The outermost part of the ear (pinna)gathers sound waves and funnels them down the auditory canal striking the eardrum.
B)The basilar membrane causes the hammer,anvil,and stirrup to vibrate,striking the oval window.
C)The auditory cones respond to the various tonal frequencies,which lead the auditory nerve to send a message to the brain.
D)The auditory nerve joins with the nasal nerve to produce an input to the olfactory lobe.

Question

Quizplus · Accepted Answer

The outermost part of the ear (pinna) gathers sound waves and funnels them down the auditory canal striking the eardrum, which causes vibrations in the ossicles (hammer, anvil and stirrup) that in turn cause the oval window to vibrate.

Answer: B 
 The basilar membrane contains hair cells that move in response to these vibrations, causing the release of neurotransmitters that stimulate the auditory nerve to send signals to the brain.

Answer: C 
 The auditory cortex in the temporal lobe receives this information and processes it into the perception of sound.

Answer: D 
 This is incorrect as the auditory nerve does not join with the nasal nerve, and the olfactory lobe is responsible for processing information related to smell, not hearing.
