Function: Collect sound from surrounding area to channel and convert into electrical impulses for the brain
A sensory organ.
* Hearing is response to sound waves.
* Part of the Nervous system.
OUTER EAR: Funnel
sound waves and funnels into the middle ear.
MIDDLE EAR: Eardrum-entrance of the middle ear.

3 bones: Hammer, Anvil & Stirrup
vibrations make each
vibrate and set off the next. Named by their shapes.
Connected to nose by Eustachian tube.
INNER EAR: COCHLEA
create waves/tappings for the neurons to bring
info to the brain to interpret.
-snail tube shaped. fluid-filled
to respond to sound waves.
loops above the cochlea to help with balance. Fluid-filled
that reacts to movement and send info to the brain to interpret and adapt . -Adjustment to position
of the head.
*STRUCTURED TO RECEIVE
VIBRATIONS TO HEAR. (CSS 5g)
SOUND: Produced by pushes of air. Waves sent away from source
of sound (ripple effect).
Travels through gases (air), liquid, and solids. (MATTER-8)

When moves away
from you= pulses slower and pitch lower.
