1

What are the five principle responsibilities of the limbic system?

Feeding, fleeing, fighting, feeling, and sex (p.415)

2

What is the function of the cerebellum?

To modulate movement and aid in coordination and balance (p.415)

3

What are the inputs to the cerebellum?

Contralateral cortex via middle cerebral peduncle and ipsilateral proprioceptive information via inferior cerebellar peduncle from the spinal cord (p.415)

4

What types of nerves provide cerebellar input?

Climbing and mossy fibers (p.415)

5

What type of information travels via the middle cerebellar peduncle to the cerebellum?

Information from the contralateral cortex (p.415)

6

What type of information travels via the inferior cerebellar peduncle to the cerebellum?

Ipsilateral proprioceptive information from the spinal cord (p.415)

7

From where does the cerebellum receive contralateral information?

Cerebral cortex (p.415)

8

From where does the cerebellum receive ipsilateral information?

Proprioceptive information from the spinal cord (p.415)

9

To where does the cerebellum send information?

To the contralateral cortex to modulate movement and to the deep nuclei (p.415)

10

What information is sent contralaterally from the cerebellum?

Information to the contralateral cortex to modulate movement (p.415)

11

What is the output pathway of information from the cerebellum to the contralateral cortex?

Purkinje fibers send information to the deep nuclei of the cerebellum which in turn send information to the contralateral cortex via the superior cerebellar peduncle (p.415)

12

What information is sent through the superior cerebellar peduncle?

Information about movement is sent from the cerebellum to the contralateral cortex (p.415)

13

What tracts are cerebellar inflow tracts and what tract is a cerebellar outflow tract?

Inflow: inferior and middle cerebellar peduncles; Outflow: Superior cerebellar peduncle (p.415)

14

What types of nerves are the output nerves of the cerebellum?

Purkinje fibers (p.415)

15

Name the deep nuclei of the cerebellum from lateral --> medial location.

Dentate, Emboliform, Globose, Fastigal (pneumonic "dont eat greasy foods") (p.415)

16

What is the primary function of the lateral cerebellum?

Voluntary movement of the extremities (p.415)

17

What is the primary function of the medial cerebellum?

Balance and truncal coordination (p.415)

18

What clinical finding is associated with a lesion to the lateral cerebellum?

Propensity to fall towards the injured side (p.415)

19

What is the function of the basal ganglia?

The basal ganglia is important in voluntary movements and in making postural adjustments (p.416)

20

From where does the basal ganglia receive its input?

From the cortex (p.416)

21

How is movement modulated by the basal ganglia?

Basal ganglia provides negative feedback to the cortex to modulate movement (p.416)

22

What are the components of the striatum of the basal ganglia?

Putamen and Caudate (p.416)

23

What is the function of the putamen?

Motor functions (p.416)

24

What is the function of the caudate?

Cognitive functions (p.416)

25

What are the components of the lentiform nucleus of the basal ganglia?

Putamen and globus pallidus (p.416)
