The sympathetic chain contains a group of cell bodies called the sympathetic chain GANGLIA. This structure contains a second cell body for the sympathetic nervous system, the first in the series being found in the THORACOLUMBAR REGIONS' lateral horn of spinal segments T1-L2. The purpose of the VENTRAL AND DORSAL rami is to carry visceral motor and visceral sensory neurons to and from this sympathetic chain.
