noun, plural: prevertebral ganglia
Sympathetic ganglia can be divided into two major groups based on their location:
Prevertebral ganglia are closely associated with the major ventral branches of the aorta. Hence, these ganglia are found near the origin of celiac artery (called celiac ganglion), and of the superior and inferior mesenteric arteries (called superior mesenteric ganglion and inferior mesenteric ganglion, respectively).
Compare: paravertebral ganglion
