Q

Shape

A

Slight skeletal differences determine favoured sport

24
Q

Extension

A

Where the angle between 2 bones increases

25
Q

Circumduction

A

Movement up, down, forwards and backwards

26
Q

Dorsi flexion

A

Movement where toes are pulled towards the knee (ankle only)

27
Q

Ligaments

A

Bands of fibres that are attached to the bones and link the joints together.
Remain under tension so bones stay pulled towards each other.

28
Q

Ligaments

A

Bands of fibres that are attached to the bones and link the joints together.
Remain under tension so bones stay pulled towards each other.

29
Q

Tendons

A

Very strong cords that join the muscle to the bone.

30
Q

Agonist

A

Muscle or group of muscles responsible for movement.

31
Q

Antagonists

A

Muscles that act to produce the opposite movement to the agonist. They work in antagonistic pairs.

32
Q

Eccentric contractionL

A

Lengthening of the muscle

33
Q

Concentric contraction

A

Shortening of the muscle

34
Q

Bursae
