Lecture 19 - Posture and the Cerebellum Flashcards
1
Q
What is the primary role of the cerebellum?
A
Evaluating the difference between intended movements and actual movements
2
Q
What can cerebellar damage result in? [5]
A
- Reduced muscle tone
- Imparied balance and motor learning
- Disrupted spatial accuracy
- Disrupted temporal coordination of movement
- Impaired cognitive functions
3
Q
What is a second important role of the cerebellum?
A
Maintenance of balance and posture
4
Q
How can patients with cerebellar damage compensate for their balance disorders?
A
- They develop stereotypes postural strategies
- E.g. Wide-based stance
5
Q
How does the cerebellum coordinate muscles?
A
It coordinates the timing and force of different muscle groups
6
Q
What role does the cerebellum play with motor learning?
A
Adapting and fine-tuning motor programs to make accurate movements through trial and error
