What parts of the ear and path of sounds through the ear?

The ear consists of three main parts: the outer ear, which collects sound waves; the middle ear, which amplifies and transmits sound vibrations; and the inner ear, which converts sound vibrations into electrical signals that are sent to the brain. Sound enters the outer ear, travels through the ear canal to the eardrum, causing it to vibrate. These vibrations are then passed through the middle ear bones (hammer, anvil, stirrup) to the cochlea in the inner ear, where they are converted to electrical signals and sent to the brain via the auditory nerve.
