How does the brain initiate a muscle contraction? Please order the steps that occur at the neuromuscular junction. = Acetylcholine binds to receptors on the surface of the muscle cell. = An electrical impulse travels down the axon of a neuron. = An action potential is generated on along the muscle cell membrane. = The electrical impulse causes acetylcholine to be released from the neuron into the synaptic cleft.

Introduction:
The mechanism of muscle contraction is explained by sliding filament theory. This theory was given by two groups of workers whose name was Andrew Huxley and Ralph Niedergerke, Hugh Huxley and Jean Hanson in 1954.
The process of muscle contraction involves several steps that is given below:
