Approximately how many different

Thousands!
What gives us the ability to make so
many different facial expressions?
Our facial muscles!
How many facial muscles do we have?
44
What is special about facial muscles?
•Most skeletal muscles attach to your bones, but
your facial muscles attach to other muscles or to
your skin.
•The result: a tiny contraction in one of the
muscles in your face pulls your facial skin and
changes your expression.
•By contracting your facial muscles in different
ways you can produce countless different
expressions.
How good are you at spotting a fake smile?
✓ GENUINE!
What differentiates a genuine smile
from a fake smile?
•Fake smiles are brought about by the cheek
muscles which pull the corners of the mouth
outwards.
•Fake smiles can be performed at will because
the brain signals that create them come from
the conscious part of the brain.
Genuine Smiles
•Genuine smiles are generated by the
unconscious brain, so are automatic.
•When people feel pleasure, signals pass
through the part of the brain that processes
emotion (the amygdala).
•As well as making the mouth muscles move,
the muscles that raise the cheeks also
contract, making the eyes crease up, and the
eyebrows dip slightly.
