When a muscle fiber is relaxed, the concentration of calcium ions is less in the sarcoplasm. As a muscle action potential travels along the sarcolemma and into the transverse tubule system, the ions release channels open in the sarcoplasmic reticulum membrane. As a result calcium ions flood in the sarcoplasm around the thick and thin ...
