Movements

Question 1

Active physiological movement

Answer 1

Muscular contraction to produce voluntary, sweeping movement of one body segment in relation to another - often involving angular change between bones

Question 2

Passive physiological movement

Answer 2

External force that creates sweeping movement of one body segment in relation to another - often involving angular change between bones

Question 3

Accessory movement

Answer 3

Involuntary, small adjustments between joint surfaces to facilitate smooth and full movement

Question 4

Active Insufficiency

Answer 4

Agonist muscle that passes over two joints can not shorten sufficiently to produce full range of movement at both joints

Question 5

Passive Insufficiency

Answer 5

Antagonist muscle that passes over two joints can not lengthen sufficiently to allow full range of movement at both joints

Question 6

Agonist/ Prime mover

Answer 6

Responsible for the movement

Question 7

Antagonist

Answer 7

Responsible for the opposing movement of the agonist

Question 8

Fixator

Answer 8

Steadies proximal attachment of agonist

Question 9

Synergist

Answer 9

Improves quality and control of the movement - prevents unwanted movement at adjacent joints
