What is the process of acetylcholine to cause muscle contraction? (5)

1) Acetylcholine made with acetyl COA and choline in axon terminal and is stored in a vesicle 2) AcH attaches to cholinergic receptor on post neuron 3) in synapse ACH is broken down by acetylcholine-esterase 4) choline is transported back into axon terminal to make more acetylcholine 5) can be released into synapse by pre or embedded into post
