Within the sympathetic trunk, preganglionic fibers usually from T1-5 spinal cord levels can ascend to other vertebral levels and synapse inside ganglia located at a more superior level. The ganglia might not necessarily be associated with inputs directly from the spinal cord (other nerves than T1-L2/3 can … See more These are similar to the ascending preganglionic, but in contrast, they descend to ganglia located at a more inferior level. This … See more After synapsing inside the ganglion, postganglionic fibers leave through a gray ramus communicans (grey due to absence of myelin) and re-enters the same anterior ramus, which it initially travelled through.
