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.
1 The axons of these postganglionic neurons then extend to the target organ.  The cell bodies of parasympathetic preganglionic neurons reside either in the brain stem or in the sacral spinal cord. The axons of these neurons project from these locations along peripheral nerves toward their target organs.
