myosin is not bound to actin

Explanation:

When the muscle relaxes the verve stimulation stops and the calcium is then pumped back into the sarcoplasmic reticulum which causes a break in the link between actin and myosin. Actin and myosin, therefore, return to their unbound state causing the muscle to relax.
