The Sarcoplasmic Reticulum is a specialized type of endoplasmic reticulum that is found in the cytoplasm of striated muscle cells [1]. The tubular structures surround the myofibrils of the muscle cell and their function is to store Ca2+ ions, until they are released when triggered by electical impulses travelling down T-tubules [2]. This triggers contraction of the muscle via the sliding filament theory [3], which occurs until the Ca2+ is actively pumped back into the sarcoplasmic reticulum.
