2. The Human Ear
The human ear is a sensory organ which helps us with
our hearing.
It is made up of three (3) parts
Outer ear
Middle ear
Inner ear

3. The Human Ear
The outer ear is made up
of the pinna, ear canal and
eardrum. It collects sound
waves which travels
through the ear canal
which causes the ear drum
to vibrate.

4. The Human Ear
The middle ear is made up
of the ossicles which are the
three tiny bones in the ear,
the hammer or malleus, the
anvil or incus and the
stirrup or stapes and the
eustachian tube. The
stirrup is the smallest bone
in the body. The sound
waves causes the ossicles to
vibrate.

5. The Human Ear
The inner ear is
made up of the
cochlea, semicircular
canal and auditory
nerve. The tiny hair
sends the vibration to
the nerves which
sends a message to
the brain.
