|Anatomical terms of neuroanatomy|
Along the length of the sympathetic trunks are ganglia known as ganglia of sympathetic trunk, sympathetic ganglia or paravertebral ganglia. The ganglia are distinguished as cervical, thoracic, lumbar, and sacral and, except in the neck, they closely correspond in number to the vertebrae.
Only the cervical ganglia have specific names. They are arranged thus:
- cervical ganglia - 3 ganglia
- thoracic ganglia - 12 ganglia
- lumbar ganglia - 4 ganglia
- sacral ganglia - 4-5 ganglia
