What is the steps in the Sliding Filament theory of muscle cell contraction in correct order? Including steps in depolarization and repolarization.

What are the chronological steps of a muscle contraction? From the start at the neuromuscular junction up until the sarcomere shortening?

What is NOT related to temporal summation for muscle contraction? residual Ca2+ in the muscle unfused tetanus recruitment of multiple motor units fused tetanus

We move a lot and do not even realize how intricate these movements may be from gross motor to fine motor manipulations. Briefly explain the steps involved in a single muscle contraction beginning at the neuromuscular junction through one complete contraction and relaxation for the sliding filament theory. Don’t forget to include all the major proteins (actin, myosin, troponin and tropomyosin) involved as well as calcium and ATP.
