Touch
• Touch is to use your skin to have physical contact
with something else.

brain

–
–

Pressure
Temperature
Pain
Vibration.
Touch
• Information from our skin travels up the spinal cord
to the brain.
• Each nerve carries information from one part of
the body.

Hearing
• Our ears allow us
to understand
sounds.
• The external ear
captures sound,
while the internal
portion processes
it.
Hearing
• Tiny bones in the
ear create
vibrations in
fluid.
• These ripples
are detected by
delicate hairs,
and signals are
sent to the brain.
Hearing
• The ears also
contain vestibular
organs that give
us our sense of
balance.
• When these get
messed up, you
become dizzy
(think of car
sickness!)
Hearing Loss
Some hearing losses are congenital (born
with). Others occur through disease or
with the aging process.
