Flashcards in Movement Control And Coordination Deck (22):
1

How does the cerebellum helps in coordination of movement?

1- evaluate the difference between intention and action.
2- refine movement in progress.
3- adapt or improve repetition.

2

The cerebral cortex is concerned with planning the movement but not.

Refining the movement

3

The final output of the basal ganglia is.

Inhibitory

4

The final output of the cerebellum is.

Excitatory

5

The basal ganglia and the cerebellum send their output to the cortex via.

The thalamus

6

An take place without basal ganglia or cerebellum.

Crude movement

7

Skilled voluntary movements can be classified into.

- Ramp movement.
- Ballistic movement.

8

Primarily controls ballistic movements.

The cerebellum

9

Primarily under control of the basal ganglia.

Ramp movement

10

Typing and saccadic eye movements

Ballistic movement

11

From vestibular and visual systems to vestibular nuclei and fastigial nucleus.

Vestibulocerebellum

12

What is the role of the vestibulocerebellum ?

Balance, gait, eye movements

13

the only region of the cerebellum to receive somatosensory inputs from the spinal cord.

Spinocerebellum

14

Compares efferent coby with somatosensory inflammations.

The spinocerebellum

15

What are the symptoms of cerebellar damage?

Ataxia - dysynergia - dysmetria

16

Concerned with motor learning.

Cerebrocerebellum

17

the sole output of cerebellar cortex.

The Purkinje cells

18

What are the three cerebellar cortical layers?

The molecular layer.
The Purkinje layer.
The granular layer.

19

Provide inhibitory inputs to the cerebellar deep nuclei.

The Purkinje cells

20

What happen to ballistic movements in cerebellar lesions?

Automatism lost

21

In cerebellar lesions the muscle tune is.

Reduced

22

What are the functions of the cerebellum?

- control of muscle tone.
- control of posture and equilibrium.
- control of voluntary movements.
- coordination of ongoing movements.
- motor learning.
