Sympathetic Trunk

Friday, August 1, 2014

The sympathetic trunk is a series of peripheral nerve ganglia located along both sides of the spinal column, from the first cervical vertebra to the coccyx, with connection to the spinal cord neurons, via spinal nerve roots. The nerve fibers coming off these ganglia are linked to different nerve plexuses of the peripheral nervous system, such as the cardiac plexus. The sympathetic trunk belongs, in turn, to the sympathetic nervous system.
