1. Dantrolene inhibits calcium release from the sarcoplasmic reticulum which reduces intracellular calcium. 2. Junctional complexes between the plasma membrane and plasma membrane and sarcoplasmic reticulum . 3. As the calcium is taken up by the sarcoplasmic reticulum , the muscle relaxes. 4. CD97 is expressed at the sarcoplasmic reticulum and the peripheral sarcolemma in skeletal muscle. 5. This gene encodes a small proteolipid that regulates several sarcoplasmic reticulum Ca 2 +-ATPases. 6. Calcium is released into the cytosol due to the deterioration of the sarcoplasmic reticulum . 7. The sarcoplasmic reticulum plays a major role in excitation-contraction coupling. 8. The remaining Ca 2 + for contraction is released from storage in the sarcoplasmic reticulum . 9. "' Istaroxime "'is an investigational drug originally patented and developed by the sarcoplasmic reticulum ., 10. Termination of crossbridge cycling can occur when is actively pumped back into the sarcoplasmic reticulum .
