According to the research, sodium moving into the muscle fiber simulates the sarcoplasmic reticulum to release calcium.
It is a cellular organelle present in muscle fibers in whose terminal muscle vesicles we will find calcium.
This calcium is what will be released when the action potential reaches the interior of the muscle cell through the T tubules.
Therefore, we can conclude that according to the research, sodium moving into the muscle fiber simulates the sarcoplasmic reticulum to release calcium.
