Cerebellum

•Key Point:  COORDINATION; Ataxia = lack of coordination

•Makes comparisons between the motor plan from the cortex and the position sense from the muscles/joints and facilitates movement precision/correction

•Influences timing and force of voluntary muscular contraction

•Finger-to-nose test

 

Cerebrum versus Brainstem

•Brainstem and diencephalon maintain homeostasis of basic/primitive functions

•Cerebrum and cerebellum coordinate, plan, and memorize higher level sensori-motor function

Two systems interact in automatic and conscious ways throughout the life cycle
