The '''sympathetic trunks''' ('''sympathetic chain''', '''gangliated cord''') are a paired bundle of nerve fibers that run from the base of the [[Human skull|skull]] to the [[coccyx]]. They are a major component of the [[sympathetic nervous system]].
==Structure==
The sympathetic trunk lies just lateral to the [[vertebral bodies]] for the entire length of the [[vertebral column]]. It interacts with the [[anterior ramus of spinal nerve|anterior rami]] of [[spinal nerves]] by way of [[rami communicantes]]. The sympathetic trunk permits [[preganglionic fibers]] of the [[sympathetic nervous system]] to ascend to spinal levels superior to T1 and descend to spinal levels inferior to L2/3.<ref>Mader S. S.

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]].

=== Relations ===
In the cervical region, the sympathetic trunk is situated upon the [[prevertebral fascia]] posterior to the [[carotid sheath]].<ref name=":3">{{Cite book |last=Standring |first=Susan |url=https://www.worldcat.org/oclc/1201341621 |title=Gray's Anatomy: The Anatomical Basis of Clinical Practice |year=2020 |isbn=978-0-7020-7707-4 |edition=42nd |location=[New York] |oclc=1201341621}}</ref>{{Rp|page=600}}
