Prevertebral ganglia

Prevertebral ganglia (or collateral ganglia, or preaortic ganglia ) are sympathetic ganglia situated along the midline, anterior to the aorta and the vertebral column. The prevertebral ganglia are the celiac ganglia (including the aorticorenal ganglia), the superior mesenteric ganglion, and the inferior mesenteric ganglion.

The paravertebral ganglia, meanwhile, are the segmental ganglia of each the sympathetic trunk situated along either side of the midline.
