Brain cerebellum video Flashcards
1
Q
What is the cerebellum?
A
- Second largest part of the brain
- Produces fine control over muscular actions
- Stores memories of movement patterns
- e.g., playing scales on a piano
2
Q
What are componets of cerebellum>
A
- Convoluted surface covered by layer of cerebellar cortex
- Left and right cerebellar hemispheres
- Each hemisphere with an anterior and posterior lobe
- separated by primary fissure
3
Q
What is Vermis?
A
- narrow band of cortex
- lies along midline between left and right lobes
4
Q
What are the three regions of cerebellum:
A
- Cerebellar cortex, outer gray matter of cortex
- internal region of white matter, arbor vitae
- Deepest gray matter layer of cerebellar nuclei
5
Q
What are the three peduncles in cerebellar?
A
Three thick nerve tracts, peduncles
* helps “fine-tune” skeletal muscle movements
* superior cerebellar peduncles
- connect cerebellum to midbrain
* middle cerebellar peduncles
- connect pons to cerebellum
* inferior cerebellar peduncles
- connect cerebellum to medulla oblongata
6
Q
The superior, middle, and inferior cerebellar peduncles connect the cerebellum to which parts of the brainstem respectively?
A
Midbrain, pons, and medulla
7
Q
What are function of cerebellar?
A
- Coordinates and “fine-tunes” skeletal muscle movements
- Helps maintain equilibrium and posture
