WebTable of Contents sarcoplasmic reticulum, intracellular system of closed saclike membranes involved in the storage of intracellular calcium in striated (skeletal) muscle cells. Each segment of the sarcoplasmic reticulum forms a cufflike structure surrounding a myofibril, the fine contractile fibres that extend the length of striated muscle cells. WebAs long as Ca ++ ions remain in the sarcoplasm to bind to troponin, and as long as ATP is available, the muscle fiber will continue to shorten. Muscle contraction usually stops when signaling from the motor neuron ends, which repolarizes the sarcolemma and T-tubules, and closes the voltage-gated calcium channels in the SR.
