- main ideas
- your ear is made up of 3 sections
- the outer ear
- it's also called the
pinna.
- it's the part of
the ear that you
can see.
- the pinna is shaped so it
can collect sound waves
- it sends these sound waves
through a narrow (estrecho)
tube called the ear canal.
- after the sound waves pass
through the ear canal, they reach
the eardrum.
- the eardrum is the last
part of the outer ear.
- when the eardrum vibrates it
passes the sound waves onto
the middle ear.
- the middle ear
- the middle ear is a small air filled
space behind the eardrum
- it contains the ossicles, which
is made up of 3 tiny bones.
- when the eardrum is vibrated by
sound, it moves these 3 tiny bones.
- the 1st one is the hammer and it's
attached to the ear drum. when it shakes it
passes the vibration through the next one
that is called the anvil.
- the anvil, in turn, passes the vibration onto
the stirrup, the smallest bone in the body.
- the inner ear
- the cochlea is the final destination of the sound
waves and it's located into the inner ear.
- the cochlea is a small snail-shaped tube
containing thousands of tiny hairs immersed in
fluid.
- when the ossicles pass the vibrations onto the
cochlea it makes waves in the fluid, wich
moves the tiny hairs.
- the movement of the waves
creates a signal which is
transmitted to your brain.
- your brain interpretes
this signals as a sound.
