Action potential arrives at motor neuron axon terminal
first step
Voltage-gated calcium channels open, allowing calcium to flow into the motor neuron
second step
Acetylcholine release from the motor neuron axon terminal is stimulated
third step
Acetylcholine diffuses across the synaptic cleft
fourth step
Acetylcholine binds to receptors on the sarcolemma to create an end plate potential
fifth step
Acetylcholinesterase degrades acetylcholine
sixth step
