A

Middle

3
Q

Peduncle: Receives info from the body, Sends to vestib/reticular

A

Inferior

4
Q

Nuclei: Control of proximal muscles

A

Fastigial

5
Q

Nuclei: Output of spinocerebellum

A

Interpose

6
Q

Nuclei: Output of cerebrocerebellum

A

Dentate

7
Q

T/F: An injury to the left side of the cerebellum results in injury to the right side.

A

False: Medial and lateral hemisphere is ‘double crossed’ so L. side injury = L. side presentation.

8
Q

Region: Coordinates head/eye mov’t and postural control

A

Vestibulocerebellum

9
Q

Region: Aids in making online corrections to limb mov’t

A

Spinocerebellum

10
Q

Region: Planning of voluntary mov’t & learning

A

Cerebrocerebellum

11
Q

Symptoms: Balance disorder, Ataxia, Limb use only in supine

A

Damage to Vestibulocerebellum and Vermis

12
Q

Symptoms: Loss of eye control (smooth pursuit)

A

Damage to Vestibulocerebellum ONLY

13
Q

Symptoms: Disrupted mov’t execution, Hypotonia, Ataxia, Intention tremor, Reflex disruption

A

Damage to Paravermis/Medial

14
Q

Symptoms: Poor time, Trouble initiating mov’t, Dysdiadochkinesia

A

Damage to Cerebrocerebellum

15
Q

T/F: If there is damage to the dentate, previously learned tasks are impossible.

A

False. Cerebellum doesn’t store memory so you can’t still performed previously learned tasks.
