Describe the functions of the three main sections of the ear.
The outer ear collects sound waves and funnels them into the ear canal and to the eardrum, which then vibrates. The middle ear transmits the waves, or vibrations, inward by means of three small bones. The inner ear contains the liquid-filled cochlea, which is lined with hair like cells that sway as a result of the vibrations. Nerves carry the information to the brain.
The outer ear amplifies electrical signals, the middle ear produces sound waves, and the inner ear filters out background noise before sending signals to the brain.
The outer ear creates sound waves, the middle ear absorbs them, and the inner ear stores them for later use.
The outer ear detects light, the middle ear processes taste, and the inner ear controls balance only.
