Motor Control NOT COMPLETED

what is motor control

ability to regulate or direct the mechanisms essential to movement

Motor action system

context of accomplishing a particular action

Sensory/Perceptual System

essential to action, perception is the integratioin of sensory impressions into pyschologically meaningful information

congnitive system

essential to motor control includes attention, planning, problem solving, motication, and emotion

Discrete movement

clear beginning and end

Continous movement

end point of the task is not an inherent characteristic of the task, but decided arbitarily by performer

Open movement

performed within a constantly changing and unpredictable environment

Closed movement

performed in relatively fixed or predictable environment

Stable movement

non moving basem

mobile movement

moving base of support

Reflex theory

reflexes are building blocks

Hierarchical Theory

brain has higher, middle, and lower levels of control, top down organization

Neuromaturational theory

based on both reflex and hierarchical theories, attributes motor development to the maturation of neural processes, CNS maturation is the primary agent for change

System Theory

recognized that you cannot understand the neural control of mocement without understanding the characteristics of teh system and the forces acting on the body

spinal cord

lowest level of the pereption/action hierarchy

brainstem

contains nuclei involved in postural control and locomotion

cerebellum

adjusts motor responses and updaes movement commands, modulates the force and range of our movements, involved in motor learning

diencephalon

contains the thalaumus and hypothalamus, thalamus processes most of the information coming to the cortex rom the many parallel input pathways

basal ganglia

higher-order cognitive aspects of motor control

cerebral hemispheres

highest level of the motor control hierarchy

neuron

communicates through synaptic transmission, lowest level in the hierarchy is a single neuron in the spinal cord
