Neuromuscular transmission

At the excitation-contraction coupling, calcium release by the sarcoplasmic * reticulum is ATP-dependent O binds to troponin C O triggers the release of adrenaline O occurs when action potential ceases 2. Which of the following best describes the correct order of events in the neuromuscular transmission in skeletal muscle? ONerve action potential -> muscle action potential -> muscle contraction Muscle action potential -> nerve action potential -> muscle contraction Muscle action potential -> muscle contraction -> nerve action potential O Muscle contraction -> muscle action potential -> nerve action potential
