prevertebral plexuses

prevertebral plexuses
autonomic nerve plexuses situated in the thorax, abdomen, and pelvis, anterior to the vertebral column; they consist of visceral afferent fibers, preganglionic parasympathetic fibers, preganglionic and postganglionic sympathetic fibers, and ganglia containing sympathetic ganglion cells, and they give rise to postganglionic fibers. The major plexuses are cardiac, pulmonary, esophageal, celiac, mesenteric, and hypogastric. All are closely related to the aorta; those in the abdomen and pelvis supply adjacent viscera by subdivisions which accompany the branches of the aorta and which are named usually after these branches, but sometimes according to the organ supplied.
