Final Exam: Cerebellum Flashcards
What are the 3 parts of the cerebellum?
- dorsal features
- ventral features
- internal features
What is contained itn the ventral features?
flocculonodular lober/ flocculus and nodulus
The internal feature of the cerebellum is white/grey matter
white
What is the main function of the cerebellum
determine, rate range and force of movements
T/F movement initiates in the cerebellum
F
What are 4 afferent pathways though the cerebellum?
- spinocerebellar
- vestibulocerebellar
- tectocerebellar
- UMNs
What are the 3 efferent pathways though the cerebellum?
- vestibular nuclei
- reticular formation
- extrapyramidal nuclei
What are the 3 tracts that lead to/from the cerebellum
- caudal cerebellar peduncles
- middle cerebellar peduncles
- rostral cerebellar peduncles
species that will be able to get up soon after birth
precocial
species that will take longer to develop their motor skills, coordination, senses
altricial
T/F cerebellar disease causes loss of function
F
T/F Cerebellar Disease does not cause paresis or paralysis
T
T/F Cerebellar disease does not cause ataxia
F
inability to judge distance or fully understand force of movement
dysmetria
over measurement in the gait response observed as greater movements of the limbs in all ranges of motion
hypermetria
List some C/S of cerebellar disease:
- ipsilateral signgs
- wide base stance
- head tremor
- truncal ataxia
- hypertonia
- hyperreflexia
- nystagmus
- opisthotonus
decerebellate posture, extended neck and thoracic limbs, flexed hips. seen in severe cases
opisthotonus
T/F cerebellum is the modulator of the menace response
t
malformation of the cerebellum. may be normal at birth and degerate
cerebellar abiotrophy
