Sympathetic ganglia are the ganglia of the sympathetic nervous system. 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. Sympathetic ganglia are the tissue from which neuroblastoma tumours arise.
