Sympathetic, or autonomic, ganglia are the ganglia of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies located closely on either side of the spinal cord. The cell bodies create long sympathetic chains that are on either side of the spinal cord. They also form para- or pre- vertebral gangalia of gross anatomy. The afferent nerve cell bodies brings information from the body to the brain. The efferent nerve cell bodies bring information from the brain to the body regarding perceptions of danger. This perception of danger can instigate the fight-or-flight response associated with the sympathetic nervous system. The fight-or-flight response is adaptive when there is a real and present danger which can be avoided or diminished through increased sympathetic activity. The fight-or-flight response is maladaptive when the danger is imagined, prolonged, or when it lasts after the threat is over. When the intensity or duration of the response is excessive, the individual may meet criteria for an anxiety disorder. Neuroblastoma tumors can arise from the sympathetic ganglia tissue.

Each ganglia within this chain are either cervical, thoeracic, lumbar, or sacral.

The postganglionic neurons extend across most of the body. I found the uncited source that was being plagerized. I reworked those sentences that were directly from the source. I then cited that source as well as others I used.
