The sympathetic trunk (sympathetic chain, gangliated cord) is a bundle of nerve fibers that runs from the base of the skull to the coccyx. There are two sympathetic trunks in the body, a right one and a left one.
The sympathetic trunk travels inferiorly from the skull, just lateral to the vertebral bodies. It interacts with the spinal nerves or their ventral root by way of rami communicantes.
The superior end of it is continued upward through the carotid canal into the skull, and forms a plexus on the internal carotid artery; the inferior part travels in front of the coccyx, where it converges with the other trunk at a structure known as the ganglion impar.
Along the length of the sympathetic trunk are ganglia known as paravertebral ganglia.
The sympathetic trunk is a fundamental part of the sympathetic division of the autonomic nervous system. It allows nerve fibers to travel to spinal nerves that are superior and inferior to the one in which it originated. Also, a number of nerves, such as most of the splanchnic nerves, arise directly from the trunks.
