About the Ear
The human ear consists of three separate sections referred to as the outer ear, the middle ear and the inner ear. The inner ear is comprised of the cochlea, Eustachian tube and auditory nerve. When sound is heard, it travels through the outer ear and middle ear, being passed along from one section to another, on the way to the inner ear.
It begins at what we call the ear, which is the skin on the outside of the head. From there, sound travels through the ear canal (this is where you can find a wax build up) until it reaches the section known as the middle ear.
Once it reaches the middle ear, sound causes the ear drum to vibrate and send the vibrations to the hammer and then the anvil. From the anvil, sound is passed to the stirrup.
Sound leaves the middle ear when vibrations created by a small bone in the middle ear, called the stirrup, pass to the cochlea. The cochlea is shaped like a seashell and contains cells that are attached to nerve fibers. These nerve fibers act as transmitters to the brain.
