1) Neuron stops firing, release of ACh stops. 2) In the symaptic cleft, ACh is broken down by acetylcholinesterase and reabsorbed. 3) In the muscle, Na+ channels close, Na+ and K+ pump reestablishes the electrical potential (repolarization). 4) Repolarization of the SR causes active transport of Ca back into the SR. 5) The Actin/Myosin bridges are broken, reactivating the myosin head. 6) With out Ca tropomyosin recovers the binding sites on actin. 7) Actin and myosin now passively slid past one another.
