Inspection of the entire diagram shows that these nerves contain axons forming two-neuron chains. The cell bodies of the first or preganglionic neurons (orange circles) are located within the thoracolumbar region of the spinal cord in the lateral grey horns.
The cell bodies of preganglionic neurons reside within the CNS and their axons extend to specialized parasympathetic ganglia outside of the CNS where they synapse on postganglionic neuron cell bodies. The axons of these postganglionic neurons then extend to the target organ.
