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.
These rootlets converge to form the dorsal roots and the ventral roots, one from each spinal cord segment. Keep in mind that the dorsal horns are the location of the cell bodies upon which the afferent nerves from the periphery synapse.
