Q

What is flexion, extension and hyper-extension?

A

The angle at the joint decreases.
The angle at the joint increases.
Increasing the angle further (e.g. past 0 degrees/normal standing position) - increasing the angle beyond 180 degrees between the bones of a joint.

Q

What is horizontal abduction and adduction?

A

Occurs in the shoulder when the arm is held straight out in front at a 90 degree angle to the body and parallel to the ground and is either moved across the body (adduction) and or away from the body (abduction).

Dorsi-flexion and plantar-flexion.

18
Q

What actions occur in the transverse plane and about a longitudinal axis?

A

Rotation

Horizontal abduction and adduction

19
Q

What is the sagittal plane?

A

Divides the body into right and left haves.

20
Q

What is the frontal plane?

A

Divides the body into front and back haves.

21
Q

What is the transverse plane?

A

Divides the body into upper and lower haves.

22
Q

What is the transverse axis?

A

Runs from side to side across the body

23
Q

What is the sagittal axis?

A

Runs from the front to back

24
Q

What is the longitudinal axis?

A

Runs from top to bottom.

25
Q

What is an agonist?

A

The muscle that is responsible for the movement that is occurring.
Contracts.

26
Q

What is an antagonist?

A

The muscle that works in opposition to the agonist (to help produce a co-ordinated movement)
Relaxes.

27
Q

What is an isometric contraction?

A

When a muscle is under tension but there is no visible movement.
It’s static

28
Q

What is an isotonic contraction?

A

When there is movement at the muscle

29
Q

What are the types of isotonic contraction?

A

Concentric contraction

Eccentric contraction

30
Q

What is a concentric contraction?

A

When a muscle shortens under tension.

31
Q

What is an eccentric contraction?

A

When a muscle lengthens under tension or performs negative work and acts like a brake.
