Q

Abduction

A

Movement in the frontal plane back toward the midline of the body

18
Q

Transverse plane

A

Divides the body into the top and bottom halves

19
Q

Internal rotation

A

Rotation of a joint towards the middle of the body

20
Q

External rotation

A

Rotation of a joint away from the middle of the body

21
Q

Horizontal abduction

A

Movement of the arm or thigh in the transverse plane from an anterior position to a lateral position

22
Q

Horizontal adduction

A

Movement of the arm or thigh in the transverse plane from a lateral position to an anterior position

23
Q

Eccentric muscle action

A

An eccentric muscle action occurs when a muscle develops tension while lengthening

24
Q

Concentric muscle action

A

When a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle

25
Q

Isometric muscles action

A

When a muscle is exerting force equal to the force being placed on it leading to no visible change in the muscle length

26
Q

Isokinetic muscle action

A

When a muscle shortens at a constants speed over the full range of motion

27
Q

Length tension relationship

A

The resting length of a muscle and the tension the muscle can produce at this resting length

28
Q

Force couple

A

Muscle groups moving together to produce movement around a joint

29
Q

Muscle synergies

A

Groups of muscles that are recruited by the central nervous system to provide movement

30
Q

Proprioception

A

The cumulative sensory input to the central nervous system from all mechanoreceptors that sense position and limb movements

31
Q

Dorsiflexion

A

Toes point up and heal down

32
Q

Plantar flexion

A

Toes pointed down and heals off the ground

33
Q

Scapular retraction

A

Adduction of scapula shoulder blades move towards the midline

34
Q

Scapular protraction

A

Abduction of scapula: shoulder blades move away from the mid line

35
Q

Scapular depression

A

Downward motion of the scapula

36
Q

Scapular elevation

A

Upwards motion of the scapula

37
Q

Force velocity curve

A

Refers to the relationship of muscles ability to produce tension at differing shortening velocities

38
Q

Motor behaviour

A

Response to internal and external environment stimuli

39
Q

Motor control

A

How the central nervous system integrates internal and external sensory information with previous experiences to produce a motor response

40
Q

Motor learning

A

Integration of motor processes through practice and experiment, leading to relatively permanent change in the capacity to produce skilled movement

41
Q

Motor development

A

The changes in motor skill behaviour over time throughout the lifespan

42
Q

Muscle synergies

A

Groups of muscle that are recruited by the central nervous system to provide movement
