1. Once the tropomyosin has moved away from the binding sites on the actin filament and ADP molecule attaches to the myosin head, causing it to get into the cocked position
2. The myosin head attaches to the actin filament
3. The myosin heads then change their angle, pulling the actin filament along
4. An ATP molecule then attaches to the myosin head, this causes the myosin head to detach from the binding sites on the actin
5. ATPase then hydrolyses ATP to ADP and inorganic phosphate
This process is a cycle and so can continue if there action potentials keep being received
