The sympathetic nervous system has a thoracolumbar outflow, meaning that its preganglionic fibers originate from the thoracic and lumbar spinal cord segments and synapse in the paravertebral ganglia. This is in contrast to the craniosacral outflow of the parasympathetic nervous system. Additionally, the postganglionic transmitter of the sympathetic nervous system is typically norepinephrine, although the exception to this is sweat glands, where the postganglionic transmitter is ACh.
