Study Notes
Sound Perception
- Sound waves are converted into electrical impulses in the cochlea, a spiral-shaped structure in the inner ear.
- The ossicles (three small bones in the middle ear) function to amplify sound vibrations, transmitting them from the eardrum to the inner ear.
- The auditory nerve plays a crucial role in the process of hearing, as it carries electrical impulses from the cochlea to the brain, where they are interpreted as sound.
- The inner ear is responsible for both hearing and balance, with the cochlea dedicated to hearing and the vestibular system involved in maintaining equilibrium.
