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.
A useful mnemonic for remembering the relationships in the spinal cord is: SAME-DAVE (sensory-afferent, motor-efferent; dorsal-afferent, ventral-efferent). In the thoracic region, the upper lumbar region and in segments of the sacral region of the spinal cord, there is also a lateral horn of gray matter. In the thoracic and lumbar regions of the spinal cord, the lateral horn contains autonomic cell bodies for sympathetic nervous system innervation to smooth muscles, cardiac muscles and glands. In the sacral region of the spinal cord, the lateral horn contains autonomic cell bodies for parasympathetic innervation to pelvic organs. The role of the lateral horn and autonomic innervation will be discussed in another module, however, it is helpful to recognize that the lateral horns exist at this point.
