Though Magellan died before the voyage was completed, he is often credited with the first circumnavigation of the Earth as he initially led the voyage. He also discovered what is now called the Strait of Magellan and named both the Pacific Ocean and South America's Tierra del Fuego.n March 22, 1518, Charles I was persuaded by Magellan and granted him a large sum of money to find a route to the Spice Islands by sailing west, thereby giving Spain control of the area, since it would in effect be west of the dividing line through the Atlantic.
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles.t permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous.
The skeletal system and the muscular system work together as the framework for the body as well as providing the pieces that allow for movement.
