Study Notes
Outer Ear Structure and Function
- The pinna collects and directs sound waves into the ear canal.
- The ear canal funnels sound waves to the eardrum and enhances certain frequencies.
- The eardrum vibrates in response to sound waves.
- The eardrum transforms sound wave energy into mechanical energy.
Middle Ear Structure and Function
- The middle ear contains three small bones called ossicles.
- The malleus (hammer), incus (anvil), and stapes (stirrup) are the ossicles.
Inner Ear Structure and Function
- The cochlea is a spiral-shaped organ in the inner ear.
- Filled with fluid and lined with tiny hair cells.
- Vibrations in the cochlear fluid cause hair cell movement.
- Movement of the hair cells converts mechanical vibrations into electrical energy.
- The auditory nerve carries these electrical signals to the brain for interpretation.
