Sodium ions moving into the cell trigger an action potential on the muscle cell The action potential sweeps across the muscle cell and down the T tubule This then causes release of ions from the terminal cisternae of the sarcoplasmic reticulum look at Figure 10 16 calcium potassium sodium

Once the acetylcholine binds to its receptor on the motor end plate that receptor is activated it opens and ions move into the myocyte calcium potassium sodium
