Exam 3: Chapter 10 Flashcards
What does the pyramidal system involve
cortex-volitional movement
What would happen if the pyramidal system is damaged
Isolated/fractionated movement would be disrupted and initial neurogenic shock following the injury
What does the extrapyramidal system involve
subcortical systems/basal ganglia
What is the function of the extrapyramidal system
muscle tone, movement strategies, anticipatory/reactionary postural control, sequencing, orientation of head and body
What does the coordination systems involve
error control
What is the function of the coordination systems
feedback/feedforward
Accuracy of movement via purkinje fibers
What does the somatosensory perceptual systems involve
ascending pathways
What is the function of the somatosensory perceptual systems
body schema
proprioception
body position in space
What does the visual and perceptual systems involve
central processing of figure ground, depth perception, optical flow
What does the executive function motivation system involve
judgement
What is the function of the executive function and motivation system
problem solving
planning movement
dual task
What does the consciousness/homeostasis system involve
arousal levels/attention
orientation
The (CNS/PNS) collects sensory information about the body and the environment
PNS
The PNS is classified by what two things
- Involvement of sensory, motor, or both
2. The location of the involvement
What are the three determinants of effective movement
Muscle tone and performance
Postural Control
Movement and coordination
Flaccidity is velocity (dependent/independent)
independent
Rigidity is velocity (dependent/independent)
independent
Spasticity is velocity (dependent/independent)
dependent
Flaccidity is on the end of (hypotonia/hypertonia)
hypotonia
Spasticity is on the end of (hypotonia/hypertonia)
hypertonia
Rigidity is on the end of (hypotonia/hypertonia)
hypertonia
Hypokinetic muscle performance and low compliance results in what type movement dysfunctions
- Inadequate force production
- Slow movement
- Poor segmentation
- Poor eccentric control
- Moves in mid-range
Hypertonic muscle tone is the result of (hypokinetic/hyperkinetic) muscle performance and (low/high) compliance
hypokinetic; low
Hypokinetic muscle performance and high compliance results in what type of movement dysfunction
- Poor force production
- poor eccentric and isometric control
- Tends to move in end range
