1

What does the pyramidal system involve

cortex-volitional movement

2

What would happen if the pyramidal system is damaged

Isolated/fractionated movement would be disrupted and initial neurogenic shock following the injury

3

What does the extrapyramidal system involve

subcortical systems/basal ganglia

4

What is the function of the extrapyramidal system

muscle tone, movement strategies, anticipatory/reactionary postural control, sequencing, orientation of head and body

5

What does the coordination systems involve

error control

6

What is the function of the coordination systems

feedback/feedforward
Accuracy of movement via purkinje fibers

7

What does the somatosensory perceptual systems involve

ascending pathways

8

What is the function of the somatosensory perceptual systems

body schema
proprioception
body position in space

9

What does the visual and perceptual systems involve

central processing of figure ground, depth perception, optical flow

10

What does the executive function motivation system involve

judgement

11

What is the function of the executive function and motivation system

problem solving
planning movement
dual task

12

What does the consciousness/homeostasis system involve

arousal levels/attention
orientation

13

The (CNS/PNS) collects sensory information about the body and the environment

PNS

14

The PNS is classified by what two things

1. Involvement of sensory, motor, or both
2. The location of the involvement

15

What are the three determinants of effective movement

Muscle tone and performance
Postural Control
Movement and coordination

16

Flaccidity is velocity (dependent/independent)

independent

17

Rigidity is velocity (dependent/independent)

independent

18

Spasticity is velocity (dependent/independent)

dependent

19

Flaccidity is on the end of (hypotonia/hypertonia)

hypotonia

20

Spasticity is on the end of (hypotonia/hypertonia)

hypertonia

21

Rigidity is on the end of (hypotonia/hypertonia)

hypertonia

22

Hypokinetic muscle performance and low compliance results in what type movement dysfunctions

1. Inadequate force production
2. Slow movement
3. Poor segmentation
4. Poor eccentric control
5. Moves in mid-range

23

Hypertonic muscle tone is the result of (hypokinetic/hyperkinetic) muscle performance and (low/high) compliance

hypokinetic; low

24

Hypokinetic muscle performance and high compliance results in what type of movement dysfunction

1. Poor force production
2. poor eccentric and isometric control
3. Tends to move in end range

25

Hypotonic muscle tone is the result of (hypokinetic/hyperkinetic) muscle performance and (low/high) compliance

hypokinetic; high

26

Hyperkinetic muscle performance and high compliance results in what type of movement dysfunctions

1. Excessive extensibility
2. Quick, imprecise movement
3. Burst of power with difficulty sustaining force
4. Tendency to move through extremes of range

27

Hyperkinetic muscle performance and low compliance results in what type of movement dysfunctions

1. Excessive force production
2. Excessive power with difficulty adapting or dampening force
3. All or nothing force with ballistic tendency
4. Poor accuracy and precision

28

What muscle tone and muscle performance correlates with hyperextensibility

Hypokinetic muscle performance and high tone

29

What muscle tone and muscle performance correlates with hypoextensibility

Hypokinetic muscle performance and low tone

30

What types of muscle performance and muscle tone have impaired force production

1. Hypokinetic muscle performance with low tone
2. Hypokinetic muscle performance with high tone
