How does the myosin head bind to actin
WebCross-bridges are the physical connections that form between the myosin heads of the thick filaments and the actin molecules of the thin filaments during muscle contraction. The process of cross-bridge formation and detachment is what allows the sliding of the filaments and the generation of force.
