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
