Describe the pathway by which sound waves are conducted in the outer, middle, and inner ear, and also how sound is transduced into neural stimuli. Include the following in your answer : cochlea, scala tympani, scala vestibule, scala media, organ of Corti, tympanic membrane, helicotrema, ear ossicles, oval window, round window, hair cells, and cochlear nerve
What will be an ideal response?
Sound waves travel into the ear and vibrate the tympanic membrane, which in turn vibrates the ear ossicles and oval window. Vibrations then travel through the scala vestibuli, helicotrema, and scala tympani inside the cochlea. While this occurs, the sound waves vibrate the scala media, which contains the organ of Corti. Hair cells in the organ of Corti respond to the vibration by initiating action potentials in the cochlear nerve, which sends impulses to the brain where sound is perceived.
