The action potential spreading along the muscle cell causes calcium gates in the sarcoplasmic reticulum to open and to release calcium ions almost immediately.
Potassium ions
sodium channels close and potassium channels open
There are 8 steps in the action of potential. They are resting potential, the sodium activates and opens, sodium enters the cell, sodium activation gate closes, potassium leaves the cell, sodium activation gates close, potassium moves further, and the potassium activation gate closes.

The nerve cell hillock is the beginning of the axon immediately after the soma. This is where the action potential originates.

The areas that have had the action potential are refractory to a new action potential.
