有關心肌放鬆的機制，(C) 鈣幫浦（ pump）將鈣離子打回肌漿網（sarcoplasmic reticulum）
About 20% of the calcium needed for the calcium pulse that triggers contraction enters from the extracellar space and, once inside, it stimulates the release of much larger amounts of Ca2+ (the remaining 80%) from the SR. .....During repolarization, calcium ions are pumped back into the SR and the extracellular space....查看完整內容 |
