Cerebellum Flashcards
List the functions of the cerebellum
- coordination of muscular activity
- regulation of muscle tone
- balance and equilibrium
- modulation of complex motor patterns
- motor learning
Which cerebellar peduncle is both afferent and efferent
Inferior cerebellar peduncle
The cerebellar afferent paths are…
*Pontine nuclei
vestibular system
spinal cord (from proprioceptors)
reticular formation
What is the function of mossy fibers
update cerebellum on status of ongoing and intended movement
What is the function of climbing fibers
Conveys information regarding movement errors to cerebellum (activated when movement deviates from planned)
The output efferent from cerebellum toward the cerebellar nuclei and vestibular nuclei are transmitted by?
purkinje axon
What inhibits cerebellar nuclei and vestibular nuclei
Purkinje fibers of cerebellum
A right lesion in the cerebellum will effect which side of the body?
Right
What is the functional name for the flocculonodular lobe?
Vestibulocerebellum
What functional area of the cerebellum regulates equilibrium?
Vestibulocerebellum
What is the function of the spinocerebellum?
Coordinates gross limb movements
What is/are the other name(s) for Spinocerebellum?
Vermis and paravermal regions
What functional area connects with the cerebral cortex?
Cerebrocerebellum
What is the name for the vertical region equivalent of the cerebrocerebellum?
Lateral hemispheres
