Superior

Question 2

Peduncle: Receives info from everywhere

Answer 2

Middle

Question 3

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

Answer 3

Inferior

Question 4

Nuclei: Control of proximal muscles

Answer 4

Fastigial

Question 5

Nuclei: Output of spinocerebellum

Answer 5

Interpose

Question 6

Nuclei: Output of cerebrocerebellum

Answer 6

Dentate

Question 7

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

Answer 7

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

Question 8

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

Answer 8

Vestibulocerebellum

Question 9

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

Answer 9

Spinocerebellum

Question 10

Region: Planning of voluntary mov’t & learning

Answer 10

Cerebrocerebellum

Question 11

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

Answer 11

Damage to Vestibulocerebellum and Vermis

Question 12

Symptoms: Loss of eye control (smooth pursuit)

Answer 12

Damage to Vestibulocerebellum ONLY

Question 13

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

Answer 13

Damage to Paravermis/Medial

Question 14

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

Answer 14

Damage to Cerebrocerebellum

Question 15

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