how do we interpret these sounds?
Pg. 298-300 (diagram pg 299)
1. Turn in safety contracts if you have them
2. NOTEBOOKS IN BACK OF CLASS
◦If you keep your notebook in class, it needs to be
moved up to the next shelf or taken home. NO
NOTEBOOKS MAY BE KEPT ON THE BOTTOM SHELFS
ANYMORE.

Interpretation?
Temporal lobe
Equilibrium: the sense of motion, body
orientation, and balance
Sensed by: Semicircular Canals
Static Equilibrium(Position in Space)
Hair cells in vestibule are
stimulated by changes in
space.
Dynamic Equilibrium
(Perception of motion)
-linear (driving forward)
-angular (turning the corner)
Movement causes hair cells in semicircular canal to bend.
Sense of Equilibrium
Try it:
Stand on one foot.
Close your eyes and stand on one foot.
How is balance affected when sight is eliminated?
What organs must we be using?
