Prevertebral ganglia

Prevertebral ganglia (or collateral ganglia, or preaortic ganglia ) are sympathetic ganglia which lie between the sympathetic chain and the organ of supply.

Function
They are the site of relay of the preganglionic sympathetic fibres that supply abdominal and pelvic viscera.

Examples
These include the celiac ganglia (which can include the aorticorenal ganglion), superior mesenteric ganglia, and inferior mesenteric ganglia.
