From Biology-Online Dictionary

Definition

noun

The prevertebral ganglion found adjacent to the origin of superior mesenteric artery.


Supplement

Prevertebral ganglia are closely associated with the major ventral branches of the aorta. Hence, these ganglia are usually found near the origin of celiac artery (as celiac ganglion), and of the superior and inferior mesenteric arteries (as superior mesenteric ganglion and inferior mesenteric ganglion, respectively).

The superior mesenteric ganglion serves as the synapsing point for one of the pre- and post-synaptic nerves of the sympathetic division of the autonomous nervous system.
