WebFeb 5, 2024 · Triads consist of two terminal cisterns of the L-system associated with a central T-tubule segment. The main function of the triads is to translate the action potential from the plasma membrane to the sarcoplasmic reticulum, effecting calcium flow into the cytoplasm and the initiation of muscle contraction.
