Man can move to move in accordance with his wishes. Free movement occurs as a result of cooperation between two organ systems, namely skeletons or skeletons and muscles. The frame composed of the bones can move because it is moved by the muscles. So, actually the skeleton does not have the ability to move itself. Therefore, the Framework is called passive motion.
In the body, muscles attach and connect various organs of the body, such as bone with bone, bone with skin, skin with skin and so forth.
Muscles have the ability to control or shorten and relax or relax. If the muscle shortens it will generate power and there is movement of organs in the lekati or the surrounding organs towards a certain. When the muscles relax then the organs will move in the opposite direction. Based on this all the muscles are called active motion tools.
A. the framework of the human body.
Frame is the arrangement of bones with a particular system. The frame lies in the body, protected or wrapped by muscles and skin. The framework contained within the body is called the inner frame or endoskeleton.
To support the function of motion, in addition supported by muscle contraction and relaxation, between the bones and the bones of one another are connected by the bone joint, the joints are equipped with tendons and ligaments. The interaction of all the supporting components of the motion will produce certain motion of an organism.
