The signal for contraction comes down the axon of a motor neuron to the neuromuscular junction.

The signal for contraction comes down the axon of a motor neuron to the neuromuscular junction. When it arrives at the axon terminal, the synaptic vesicles fuse with the membrane and release the neurotransmitter (acetylcholine) into the synaptic cleft.
