ABSTRACT
The motor system of the body comprises everything which has to do with carrying out human movement. Human movement is the arbitrary and spontaneous alteration of the position of the body in space with relation to the environment, or the alteration of the position of the limbs with regard to the body as a whole. Before the movement takes place, the limb or the body has a certain posture. When the movement has finished, the body or the limb has assumed a different position.
