-
The Outer Ear,
is known as the pinna, the sound that
you ultimately hear is collected by the pinna.
-
Next is the ear
canal, which is between the outer and middle ear. This passes the sound
wave collected by the pinna to the middle ear.
-
The middle ear
is next in line and when the sound waves reach this part they are turned
into vibrations and then taken to the inner ear.
-
But bang between
the middle ear and the outer ear is also the eardrum, which helps the
middle ear convert the sound waves into vibrations.
-
The ossicles
also form a part of the ear. These are three tiny bones. The first of
which, the hammer is connected to the eardrum. The hammer is attached
to the anvil which in turn is connected to the stirrup –that you’ve
got to note is the smallest bone in your body.
-
There is also
the Eustachian tube, which is the connecting point for your nose and
middle ear. This can also help you understand the popping sound you
hear, because the Eustachian tube assists in handling pressure. It opens
up when you are climbing a mountain or flying in a plane to maintain
the pressure equal on both sides of your eardrum.
-
The Cochlea in
the inner ear is a small curled up tube, which has the tiniest hairs
on its surface as well as some fluid.
-
Just above the
Cochlea are three small loops called the semi-circular
canals, which
are also filled with liquid as well as tiny hairs.
