A

Horizontal abduction and horizontal adduction

26
Q

What is flexion

A

Decreasing the angle between the bones of a joint

27
Q

What is extension

A

Increasing the angle between bones of a joint

28
Q

What is plantar flexion

A

Pointing the toes/pushing up on to your toes

29
Q

What is dorsi flexion

A

Pulling the toes up to the shin

30
Q

What is hyper extension

A

Increasing the angle beyond 180° between the bones of a joint

31
Q

What is abduction

A

A movement away from the midline of the body

32
Q

What is adduction

A

A movement towards the midline of the body

33
Q

What is horizontal abduction

A

Movement of the body part backwards across the body to abduction

34
Q

What is horizontal adduction

A

The movement of the body part forwards across the body at 90° to adduction

35
Q

Define agonist

A

The muscle that is responsible for the movement that is occurring, the muscle which contracts whilst the movement happens

36
Q

Define antagonist

A

The muscle that works in opposition to the agonist, the muscle that is relaxing while a movement happens

37
Q

Can there be more than one agonist

A

Yes there can although this does depend on the type of movement that is being performed
