Motor Behavior

Motor behavior is the action that results in human movements and comprises motor learning, control, and development. It constitutes all movements, from involuntary to voluntary actions in every part of the human body that starts from head to toe. Every movement depends on generating, controlling, and managing the forces required for the muscles and biomechanics.
