How the human ear hears sound?

1. The outer ear picks up the sound vibrations

2. These sound waves travel through the ear canal

3. The eardrum vibrates and make 3 tiny bones in the middle ear move

4. These bones send these vibrations to the shell-shaped structure called choqlea

5. The sound vibrations make the liquid in the cocheleq move making the hair move back and forth

6. The hair are joined to the nerves and send signals to your brain
