Why sarcoplasmic reticulum is important?

Web21 jul. 2024 · The SR releases calcium ions at the terminal cisternae via the receptor, ryanodine receptor (RyR). When RyR is activated, it opens to release calcium ions. The release of stored calcium ions from the SR is called calcium spark. Calcium spark may either be evoked or spontaneous. WebThe sarcoplasmic reticulum is a complex network of specialized smooth endoplasmic reticulum that is important in transmitting the electrical impulse as well as in the storage of calcium ions. These longitudinal tubules form a membrane-bound system of tubules and cisterns that surround the myocytes.
