____ sodium and other cations flow into the cell
____ ACh is released from a motor neuron
____ ACh binds receptors on the motor end plate
____ voltage-sensing ryanodine receptors allow an influx of calcium ions
____ high intracellular calcium levels allow tropomyosin to move out of the way of myosin binding sites
____ calcium is released from intracellular storage in the sarcoplasmic reticulum
____ myosin heads bind actin and muscle contraction ensues if ATP levels are adequate
