Multiple diseases can affect the muscular system. Muscular system The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body.

Together with the skeletal system, it forms the musculoskeletal system, which is responsible for movement of the human body.
The Description of the Human Body soul. A sick or injured body does not do what we want or moves in ways we do not want. He believed the death of the body stopped it from being fit to bring about movement. This did not necessarily happen because the soul left the body.

He felt we all know what the human body is like because animals have similar bodies and we have all seen them opened up. He saw the body as a machine.
