We have the white matter and we have the gray matter. So the cell body and the dendrites of the motor neuron in the somatic nervous system always begin within our spinal cord. So let's suppose I want to actually move my bicep. What happens is my brain initiates creates that electrical signal in the form of an action potential and that action potential travels and eventually ends up on the dendrites of our somatic motor neuron. And that dendrite picks up that signal and once the signal is picked up by the dendrites it sends it through the axon of our body. So the axon of the somatic motor neuron.
