Explanation:
Muscle contracts when myosin heads make a cross-bridges (bonds) with actin and the heads bend pulling the actin filament deeper among the myosin filaments. As far as Ca2+ and ATP is present (around the Actin and Myosin) the cycle : binding, bending, releasing and straightening of myosin heads continue (contraction).
