Flashcards in 05 Cerebellum Deck (20):
1

Aka vestibulocerebellum
Important in maintaining balance
Dorsolateral

Archicerebellum

2

Archicerebellum persists in human as the ____

Flocculonodular lobes

3

Deepest of all fissures in the cerebellum
Basis for subdividing the cerebellum into the posterior and anterior lobes

Primary fissure

4

Aka paleocerebellum or anterior lobe
Important in locomotion

Spinocerebellum

5

Aka cerebrocerebellum, pontocerebellum or posterior lobe
Lateral parts of the cerebellar hemispheres

Neocerebellum

6

2 types of inhibitory interneurons

Stellate cell
Basket cell

7

Primary integrative neuron of the cerebellum
Distinct to the cerebellum
Contains only one neuron type and is only one layer thick
Provide the only output from the cerebellar cortex
Receive input from the contralateral inferior olivary nucleus from the brainstem via the climbing fingers

Purkinje cells

8

Present in cerebrum, hippocampus and cerebellum
Outermost layer
Contains two types of interneurons

Molecular cells

9

Most numerous neurons
Receives inputs from the pontine nuclei which in turn gives rise to the crisscrossing mossy fibers which then forms the middle cerebellar peduncle

Granule cells

10

Glutamatergic interneurons in the cerebellar cortex and dorsal cochlear nucleus
Receive glutamatergic inputs and make glutamatergic synapses with granule cells and others

Unipolar brush cells

11

Provide inhibitory feedback to the granule cell

Golgi cells

12

Largest
Deep in the lateral hemispheres
Efferent fibers from most of the superior peduncle

Dentate

13

Together with the globose nucleus is referred to as interposed nucleus

Emboliform

14

Contains primarily large and small multipolar neurons

Globose

15

Most primitive cerebellar nuclei
Found in the vermis
Has connections with CN VIII and medial longitudinal fasciculus

Fastigial

16

Aka restiform body
From the medulla to the cerebellum
From spinal cord and lower brainstem
Climbing fibers from contralateral inferior olivary

Inferior cerebellar peduncle

17

Aka brachium pontis
Connects the two cerebellar hemispheres
Major afferent fibers from cerebrum and pons

Middle cerebellar peduncle

18

Aka brachium conjunctivum
Counterpart of the midbrain
Mostly output from the cerebellum

Superior cerebellar peduncle

19

Portion of the superior cerebellar peduncle
From the dentate nucleus
Gives the cerebellum a distinct feature, wherein a right cerebellum problem would manifest on the right side of the patient

Double decussation pathway

20

Double decussation pathway comprises the

Dentarubrothalamocortical tract
Cerebellothalamocortical tract
