Study Notes
The Ear's Structure and Function
- The ear canal, or external auditory meatus, transmits sound waves from the external ear to the middle ear.
- The eustachian tube is responsible for equalizing air pressure between the middle ear and the atmosphere.
- The external auditory canal is approximately 2.5 cm (1 inch) in length.
- The cochlea, a structure in the inner ear, converts sound vibrations into electrical signals.
- The pinna, or auricle, collects and directs sound waves into the ear canal in the external ear.
