Most of the nerves supplying the abdominal and pelvic viscera do not synapse in the paravertebral chain. Insead they are carried to the prevertebral ganglia where they
     synapse. What is the name given to the nerves that carry the fibres from the paravertebral chain to the prevertebral chain?
 

The cervical part of the sympathetic chain is found running along the prevertebral region and consist of the:
superior cervical ganglion (1)
middle cervical ganglion (2)
inferior cervical ganglion (3)
1st thoracic ganglion (4)
Notice that the cupola of the lung extends up into the root of the neck (5).
