Explanation: 

Detailed explanation-1: -The sliding filament theory explains how myosin and actin interact to cause a muscle contraction. There are 5 stages: resting, excitement-contraction, contraction, recharge, and relaxation.

Detailed explanation-2: -1) An AP travels down the axon. to the axon terminal. 2) Electrical gated calcium channels open. 3) Calcium causes the vesicles to. 4) ACH diffuses across the synaptic cleft. 5) ACH binding opens ion channels. 6) If the muscle reaches the threshold (-55mv) at the motor end plate. 7) ACH is broken down by.
