B3 - Antagonistic Pairs

An agonist is...

• ...the ‘prime mover’ that contracts to cause the movement

• ...the opposite muscle that has to relax to allow movement

• ...a muscle that stabilises the body to stop any unwanted movement at a joint

• ...a muscle that assists the 'prime mover' in a particular movement

An antagonist is...

• ...the ‘prime mover’ that contracts to cause the movement

• ...the opposite muscle that has to relax to allow movement

• ...a muscle that stabilises the body to stop any unwanted movement at a joint

• ...a muscle that assists the 'prime mover' in a particular movement

An fixator is...

• ...the ‘prime mover’ that contracts to cause the movement

• ...the opposite muscle that has to relax to allow movement

• ...a muscle that stabilises the body to stop any unwanted movement at a joint

• ...a muscle that assists the 'prime mover' in a particular movement

An synergist is...

• ...the ‘prime mover’ that contracts to cause the movement

• ...the opposite muscle that has to relax to allow movement

• ...a muscle that stabilises the body to stop any unwanted movement at a joint

• ...a muscle that assists the 'prime mover' in a particular movement
