Q

What term refers to uncoordinated speech due to cerebellar damage?

A

dysarthria

17
Q

The indirect inputs to the dentate nucleus come from what part of the cerebellar cortex?

A

lateral zone

18
Q

The left hemisphere can understand

A

language

19
Q

The right hemisphere sees whats on the left but cannot nsma it because it is

A

non-verbal

20
Q

General function of the cerebellum is

A

Timing of motor activites,; controls Rapid muscle movements, contraction intensity with load change; controls agonist/antagonist coordination; Posture/equilibrium

21
Q

General function of Basal Ganglia

A

plan/control comlex movement patterns; intensities of separate movements, driection of movement, sequencing of successive, parallel movents to achieve complex motor goals.

22
Q

Cerebellar functional central zone

A

vermis

23
Q

What is the function of the vermis?

A

control axial body, neck, shoulders and hips

24
Q

What zones are included in hemispheres?

A

Intermedate and lateral zones

25
Q

Which specific zone coordinates distal limbs, especially the hands and feet?

A

Intermediate zone of hemisphere

26
Q

The lateral zone has what cerebral function?

A

planning sequential movements with the cerebral cortex

27
Q

Cerebellum is connected to the brain via the

A

superior middle and inferior cerebellar peduncles

28
Q

The tree structure in the white mater is called?

A

Arbor vitae

29
Q

The gray mater is composed of

A

Folia of cerebellar cortex and Deep cerebellar nuclei

30
Q

vermis and intermediate zones both have

A

toptgraphical representation

31
Q

Axial parts, limbs and facial regions lie in the

A

Intermediate zones

32
Q

Anterior and Posterior lobes of the cerebellar are

A

mirror images

33
Q

Cerebellum Motot function

A

receives continuous updated info about intended motor actions; no direct motor contraction; Continuous sensory info (proprioception) for position and body movement; compares actual with intended movement, sends correct signal back to motor system;

34
Q

what motor function aids cerebral corte in planning movement sequence while in motion and learns from mistakes?

A

cerebellum
