The nurse assists and educates clients about the structure and function of the sensory system. The nurse is showing the client the path taken by sound waves to reach the brain. The nurse dropped the note cards with the correct sequence on the floor

Question

The sequence of steps is scrambled and needs to be placed in the correct order. 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
