The mechanism of hearing involves several steps:
1. Sound waves enter the outer ear and travel through the ear canal.
2. The sound waves reach the eardrum (tympanic membrane) and cause it to vibrate.
3. The vibrations from the eardrum are transmitted to the three small bones in the middle ear called the ossicles (malleus, incus, and stapes).
4. The ossicles amplify the vibrations and transmit them to the oval window, a membrane-covered opening that leads to the inner ear.
5. The vibrations cause the fluid in the cochlea (a spiral-shaped structure in the inner ear) to move.
6. As the fluid moves, it stimulates thousands of tiny hair cells (cilia) lining the cochlea.
7. The movement of the hair cells generates electrical signals that are transmitted to the auditory nerve.
8. The auditory nerve carries the electrical signals to the brain, where they are interpreted as sound.
Overall, the mechanism of hearing involves the conversion of sound waves into electrical signals that can be processed by the brain to perceive sound.
