Q
- What is the main function of the cerebellum?
- At what level does the cerebellum SEND impulses to the rest of the brain, and what points does the cerebellum RECIEVE impulses form the rest of CNS?
- What happens when the cerebellum has been injured?
A

Q
Cerebellar Peduncles (CPs)
- Inferior CP
- What 2 bodies make up this structure?
- Where do the fibers in this bundle usually arise from?
- Middle CP
- What brainstem structure is this continues with?
- How does this relate to the fibers that are in this bundle?
- What brainstem structure is this continues with?
- Superior CP
- Does this bundle contain mostly afferent or efferent fibers?
- Where do these fibers originate?
- Where do these fibers desicate?
- Does this bundle contain mostly afferent or efferent fibers?
A

Q
Cerebellar Lobes and Fissures
- What are 3 lobes?
- What fissures divide the 3 lobes?
- What fissure separates the superior and inferior surfaces of the cerebellum?
- What 3 regions can be made if you divide the cerebellum rostrocaudally?
A
7
Q
Cerebellar Nuclei
- What are the 4 cerebellar nuclei?
- For the nuclei functionally related to the vermis zone:
- Where are the located, relative to the midline?
- Through what structure do they project into the brainstem, and what neurotransmitter do they rely on?
- Which 2 nuclei are functionally related to the intermediate zone of the cerebellum?
- For the nuclei that are functionally related to the lateral zone:
- What can you note about their general appearance?
A

Q
Cerebellar Nuclei
- Globes, emboliform, and dentate nuclei
- Do these have efferent or afferent innervation?
- What structure do they exit the brainstem via? Where do their projections terminate?
- What neurotransmitters do they rely on, and what effect does this have on their type of innervation?
A
