Chp 10 Human Physiology

Cerebral Cortex:

Planning and ongoing control of voluntary movements

Subcortical and Brainstem Nuclei:

learning skilled movements, role in planning and monitoring movement, Interact with cortex to control movemen

Basal Nuclei

Facilitate or surpresses movements, selects movements, surpesses unwanted/competing movements and initiates selectef movements

Cerebellum

posture and movement indirectly, Plays a role in the coordination of movements with multiple joint, Plays a role in timing of phases of motor activities, compares actual movement to planned movement and adjust motor program

Cerebellar disease

Unstable posture and an awkward gait, Hard to start or stop a movement, Cannot perform limb or eye movements smoothly, but move with a tremor
