Hearing and the Structure of the Ear

Question 1 • Psychology A

Which of the following correctly lists the structures through which sound travels after entering the ear?

Answer
A
auditory canal, eardrum, ossicles, cochlea
B
ossicles, eardrum, cochlea, auditory canal
C
eardrum, auditory canal, ossicles, cochlea
D
cochlea, eardrum, ossicles, auditory canal

Explanation

Sound travels through the auditory canal and strikes the eardrum, causing it to vibrate. The vibrations pass through the ossicles, the tiny bones of the middle ear, and then reach the cochlea, where they are converted into signals for the brain. Thus, the correct sequence is “auditory canal, eardrum, ossicles, cochlea.”
