The chain extends from the upper neck down to the coccyx, forming the unpaired coccygeal ganglion. Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. They are the site of relay of the postganglionic sympathetic fibres that supply abdominal and pelvic viscera. Prevertebral ganglia (or collateral ganglia, or preaortic ganglia) are sympathetic ganglia which lie between the sympathetic chain and the organ of supply. They deliver information to the body about stress and impending danger, and are responsible for the familiar fight-or-flight response. They contain approximately 20000–30000 nerve cell bodies and are located close to and on either side of the spinal cord in long chains. The bilaterally symmetric sympathetic chain ganglia, also called the paravertebral ganglia, are located just ventral and lateral to the spinal cord. Sympathetic ganglia are the ganglia of the sympathetic nervous system. Sympathetic ganglia are the tissue from which neuroblastoma tumours arise.
