Muscles and Bones

See how muscles, bones, and connective tissue work together to allow movement. Observe how muscle contraction arises from the interactions of thin and thick filaments in muscle cells. Using what you have learned, construct an arm that can lift a weight or throw a ball. Connective tissue, muscle composition, bone length, and tendon insertion point can all be manipulated to create an arm to lift the heaviest weight or throw a ball the fastest.
