Which progression represents a correct sequence in the sense of hearing?
A) Eardrum, pinna, oval window, vestibular canal
B) Auditory canal, vestibular nerve, eardrum
C) Pinna, eardrum, oval window, basilar membrane
D) Pinna, basilar membrane, cochlea, tympanic membrane

Question

Quizplus · Accepted Answer

The correct sequence of the hearing process is as follows: Pinna (auricle) collects sound waves from the environment, which cause the eardrum to vibrate. The vibration of the eardrum causes the ossicles (malleus, incus, and stapes) to move, which leads to the movement of the oval window. The movement of the oval window creates waves in the fluid-filled cochlea, which cause the basilar membrane to vibrate. The vibration of the basilar membrane stimulates the hair cells, which send signals through the auditory nerve to the brain. Therefore, the correct sequence is Pinna, eardrum, oval window, and basilar membrane. None of the other choices represent the correct sequence.
