the main parts of the human ear and how they contribute to our
The human ear has three main sections,
which consist of the outer ear, the middle ear, and the inner
ear. Sound waves enter your outer ear and travel through your
ear canal to the middle ear. The ear canal channels the waves
to your eardrum, a thin, sensitive membrane stretched tightly
over the entrance to your middle ear. The waves cause your eardrum
to vibrate. It passes these vibrations on to the hammer, one of
three tiny bones in your ear. The hammer vibrating causes the
anvil, the small bone touching the hammer, to vibrate. The anvil
passes these vibrations to the stirrup, another small bone which
touches the anvil. From the stirrup, the vibrations pass into
the inner ear. The stirrup touches a liquid filled sack and the
vibrations travel into the cochlea, which is shaped like a shell.
Inside the cochlea, there are hundreds of special cells attached
to nerve fibers, which can transmit information to the brain.
The brain processes the information from the ear and lets us distinguish
between different types of sounds.
