1. Sound enters into the OUTER EAR 2. The waves then go through the AUDITORY CANAL 3. to then the EARDRUM, tight membrane, causing it to vibrate 4. then goes to the OSSICLES (consisting of hammer, anvil, and stirrup) which picks up the vibrations. 5. the incoming vibrations cause the cochlea's membrane (the OVAL WINDOW) to vibrate, jostling the fluid that fills the tube. 6. the motions then causes ripples in the BASILAR MEMBRANE (axons form the auditory nerve). 7. bending the HAIR CELLS lining the surface of the basilar membrane. 8. Axons of those cells converge to form the auditory nerve, which sends neural messages (via the THALAMUS). 9. auditory cortex of the temporal lobe

Answer :

Final answer:

The process being described is the pathway of a sound wave through the human ear, from entering the outer ear to being interpreted by the brain via the auditory nerve.

Explanation:

The question is describing the process of how we hear sound, which is primarily a function of the inner ear. The journey of the sound wave begins when it enters the outer ear and travels down the auditory canal. It then reaches the eardrum, causing it to vibrate. These vibrations are amplified by the ossicles - a group of three bones known as the hammer, anvil, and stirrup. The amplified vibrations reach the cochlea's membrane known as the oval window, activating the fluid inside the cochlea. This results in ripples forming in the basilar membrane, moving the hair cells present on its surface. These hair cells transform the mechanical movement into electrical signals that are sent to the brain through the auditory nerve, passing through the thalamus and ending up in the auditory cortex of the temporal lobe where they are processed into the sounds we perceive.
