1

Fill the blank: If the patient had lesions in the ___ or ___ they wouldn't be able to sit up.

Vermis, Flocculonodular lobe

2

There are 6 joints being coordinated by the cerebellum with the finger to nose test. The ____ is where the heel of one foot run up and down along the shin of the other leg. Question 2:What joints are being coordinated here?

heel to shin test; Question 2: DIP, PIP,MCP, radiocarpal, Elbow and GH joints

3

What is it called when a patient sways when standing?

titubation

4

Which part of the basal ganglia degenerates in Parkinson's patients?

Dopamine neurons in the substantia nigra

5

What neurotransmitter is deficient?

Dopamine

6

What is given to treat Parkinson's patients (that can cross the blood brain barrier)?

L-DOPA

7

What is a phoneme?

a distinct unit of sound, like the "b" sound in the word bat.

8

What afferent pathway invloves the flocculonodular lobes?

vestibulocerebellar

9

This type of cortical neuron has short axons, and therefore acts as interneurons within the cerebral cortex

Granular (Stellate) cells

10

Which pathway through the basal ganglia executes learned patterns of movement?

Putamen circuit

11

what part of the cerebellum coordinates the muscles of the trunk, neck, shoulder, and hips?

Vermis

12

Layer VI of the cerebral cortex generally has what function?

output to the thalamus

13

What is NOT a symptom of Parkinson's disease?

Intention tremor

14

The part of the brain that coordinates the motor activity for speech is

Broca's area

15

Which deep cerebellar nucleus functions in coordination of distal limb agonists and antagonists?

interposed

16

What term refers to uncoordinated speech due to cerebellar damage?

dysarthria

17

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

lateral zone

18

The left hemisphere can understand

language

19

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

non-verbal

20

General function of the cerebellum is

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

21

General function of Basal Ganglia

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

22

Cerebellar functional central zone

vermis

23

What is the function of the vermis?

control axial body, neck, shoulders and hips

24

What zones are included in hemispheres?

Intermedate and lateral zones

25

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

Intermediate zone of hemisphere

26

The lateral zone has what cerebral function?

planning sequential movements with the cerebral cortex

27

Cerebellum is connected to the brain via the

superior middle and inferior cerebellar peduncles

28

The tree structure in the white mater is called?

Arbor vitae

29

The gray mater is composed of

Folia of cerebellar cortex and Deep cerebellar nuclei

30

vermis and intermediate zones both have

toptgraphical representation

31

Axial parts, limbs and facial regions lie in the

Intermediate zones

32

Anterior and Posterior lobes of the cerebellar are

mirror images

33

Cerebellum Motot function

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

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

cerebellum
