(ganglion phrenicum). This plexus distributes branches to the inferior vena cava, 

 and to the suprarenal and hepatic plexuses. 



The hepatic plexus (plexus hepaticus), the largest offset from the celiac plexus, 

 receives filaments from the left vagus and right phrenic nerves. It accompanies 

 the hepatic artery, ramifying upon its branches, and upon those of the portal vein 

 in the substance of the liver. Branches from this plexus accompany all the divisions 

 of the hepatic artery. A considerable plexus accompanies the gastroduodenal 

 artery and is continued as the inferior gastric plexus on the right gastroepiploic 

 artery along the greater curvature of the stomach, where it unites with offshoots 

 from the lienal plexus.

The lienal plexus (plexus lienalis; splenic plexus) is formed by branches from the 

 celiac plexus, the left celiac ganglion, and from the right vagus nerve. It accom- 

 panies the lienal artery to the spleen, giving off, in its course, subsidiary plexuses 

 along the various branches of the artery.
