The Correct Sequence for a Sound (A Vibration)traveling into the Mammalian

Question

The correct sequence for a sound (a vibration)traveling into the mammalian ear would be listed as
A)pinna,tympanum,ossicles of middle ear,oval window,basilar membrane,hair cell
B)tympanum,pinna,ossicles of middle ear,hair cell,oval window,basilar membrane
C)pinna,ossicles of middle ear,tympanum,basilar membrane,oval window,hair cell
D)hair cell,pinna,basilar membrane,ossicles of middle ear,tympanum,oval window
E)pinna,oval window,tympanum,basilar membrane,ossicles of middle ear,hair cell

Accepted Answer

The correct sequence of sound traveling into the mammalian ear is pinna (outer ear), tympanum (eardrum), ossicles of middle ear (malleus, incus, and stapes), oval window (membrane in the inner ear), basilar membrane (in the cochlea of the inner ear), and finally triggering the hair cell to send a signal to the brain. Choice A lists these structures in the correct order.
