prevertebral ganglia


Also found in: Wikipedia.

pre·ver·te·bral gan·gli·a

the sympathetic ganglia (celiac, aorticorenal, and superior and inferior mesenteric) lying anterior to the vertebral column, as distinguished from the paravertebral ganglia of the sympathetic trunk; these prevertebral ganglia occur mostly around the origin of the major branches of the abdominal aorta; all are in the abdominopelvic cavity; the neurons that make up the ganglia send postsynaptic sympathetic fibers to abdominopelvic viscera through periarterial plexuses.

prevertebral ganglia

collections of postganglionic sympathetic neuronal cell bodies in recognizable aggregations along the abdominal prevertebral plexus. They include the celiac, superior mesenteric, aorticorenal, and inferior mesenteric ganglia and play a critical role in the innervations of the abdominal viscera.

The sympathetic ganglia (celiac, aorticorenal, superior and inferior mesenteric) lying in front of the vertebral column, as distinguished from the ganglia of the sympathetic trunk (paravertebral ganglia); these ganglia occur mostly around the origins of the major branches of the abdominal aorta; all are in the abdominopelvic cavity, concerned with innervation of abdominopelvic viscera.
