Which is the correct order of the steps in the path taken by sound waves to the brain?
1) Sound waves enter through the ear's external auditory canal and strike the tympanic membrane.
2) The stapes vibrates against the membrane, setting the fluid of the cochlea in motion, which in turn passes on to the hair-like nerve ending in the organ of Corti.
3) The stimuli in the organ of Corti are sent to the vestibulocochlear nerve and then to the temporal lobe in the cerebral cortex, where the sounds are interpreted.
4) The tympanic membrane vibrates at various speeds in response to various pitches of sounds.
5) The ossicles within the middle ear act as a moveable bridge to transmit these vibrations to the oval window, which amplifies the sound waves.
A) 1, 3, 4, 2, 5
B) 1, 4, 5, 2, 3
C) 3, 4, 1, 2, 5
D) 4, 5, 1, 2, 3

Quizplus · Accepted Answer

The correct sequence starts with sound waves entering the ear and striking the tympanic membrane (1), followed by the tympanic membrane vibrating (4), then the ossicles transmitting these vibrations to the oval window (5), the stapes setting the cochlea's fluid in motion (2), and finally, the signals being sent to the brain for interpretation (3).
