A complex process involving the coordinated contraction of muscles due to the transmission of impulses sent from the motor cortex to it’s motor units.

• Motor Control

• Motor Complex

• Motor Systems

• Organization of Motor Control

The process of initiating, directing, and grading purposeful voluntary movement.

• Motor Development

• Motor Systems

• Motor

• Motor Cotrol

Highest level of motor control.

• Pre-command level

• Projection level

• Segmental Level

• Organization of Motor Control

The spinal cord is under the direct control of this level

• Pre-command level

• Projection level

• Segmental Level

• Organization of motor control

The lowest level on the motor control hierarchy and consists of reflexes and spinal cord circuits that control automatic movements.

• Projection level

• Pre-command level

• Segmental Level

• Open-loop control

Movement programs are executed without consideration of the effects they are having.

• Open-loop control

• Closed-loop feedback control

• Feedforward control

• Spinal Cord

Used in the execution of slow movements.

• Closed-loop feedback control

• Open-loop control

• Feedforward control

• None of the choices

Also uses what has been learned via trial and error of previously executed movements. Most movements are likely controlled by both feedback and feedforward control mechanisms.

• Open-loop control

• Spinal Cord

• Closed-loop feedback control

• Feedforward control

The movement starts as demands expressed as “_____” by the limbic system.

• Needs

• Wants

• Cerebellum

• Cerebral Cortex

The movement starts as demands these are then analyzed by the _______, which selects the appropriate strategy.

• Motor

• Cerebellum

• Cerebral Cortex

• Spinal Cord
