Now, notice the body of this neuron, the axon, not the body, the cell body, is within the central nervous system. But notice our axon of the motor neuron is located entirely in the peripheral nervous system. So our electrical signal, the action potential, travels and eventually ends up at our axon terminal. Now, the axon terminal is right next to our cell membrane of the muscle cell. In this case, let's say it's a skeletal muscle found inside my bicep. So if we zoom in on a synapse, this is basically our neuromuscular junction.
