Document Summary
Examine each of the organs in the ear, from the outer ear to the cochlea as shown in your textbook. You can contrast the place and frequency theories of hearing by noting the parts of the cochlea that react to different frequencies (the place theory). When the stirrup pushes against the oval window, it sets up vibrations in the inner ear. This moves the fluid in the cochlea back and forth and sets the hair cells in motion, causing a messafe to be sent to the brain via the auditory nerve. Remember the auditory structures by using these hints: Hammer, anvil, and stirrups - these are the middle ear structures involved in conduction of the sound wave. Paul revere rode a horse (using the stirrups) to conduct information. Basilar membrane - like the strings of a double bass, this membrane vibrates in response to sound waves. Organ of corti - structure containing the hair cells.
