ANATOMY IX A NUTSHELL. 1 2 5 



This plexus, like the cardiac plexus, is made up of sympathetic nerves plus 

 somatic nerve, which is the tenth cranial. 



Phrenic ob Diaphragmatic Plexus. 



This plexus accompanies the phrenic artery and is larger on the right than 

 on the left side. At its point of junction with the phrenic nerve is the Ganglion 

 diaphragmaticum. This plexus is situated on the under surface of the Dia- 

 phragm near the supra renal capsule. Its branches are distributed to (1) In- 

 ferior vena cava. (2) supra renal capsule, and (3) hepatic plexus. There is no 

 ganglion on the left side. It receives branches from the semilunar ganglia and 

 solar plexus, also from the phrenic nerve. This plexus gives off branches to the 

 Diaphragm and the supra renal capsules. 



Supra Renal Plexi s. 



This plexus surrounds the supra renal artery and its branches are of large 

 size. At its junction with the great splanchnic nerve is found a ganglion. It 

 receives branches from the solar plexus and semilunar ganglia, also from the 

 phrenic nerve and the diaphragmatic plexus. It distributes branches to the 

 medullary portion of the suprarenal capsules. 



Renal Plexus. 



This plexus surrounds the renal artery and contains groups of ganglion 

 cells. Its brandies of distribution enter the hilum of the kidney. This plexus 

 receives branches from the solar plexus ami semilunar ganglia, also from the 

 aortic plexus and smallest splanchnic nerves. It sends branches of distribu- 

 tion to the substance- of the kidn< y, the sp< rmatic plexus anel the inferior vena 

 cava. 



Spermatic Plexus. 



This plexus accompanies the spermatic vessels to the testes. It rec< ives 

 branches from the renal, aeirtic, anel pelvic plexus. It elistributes branches to 

 the spermatic vessels, vas deferens, and the testes. 



In the female this plexus follows the course of the round ligament to the 

 ovarian plexus and i> distributed to the ovaries and fundus of the uterus. 



Cosliac Plexus. 



This plexus is a direct continuation of the solar plexus and surrounds the 

 coeliac axis. It receives branches from the solar plexus, the lesser splanchnic 

 nerves, and the right vagus. It sub-divides into the (1) gastric plexus, (2) 

 hepatic plexus. (3) splenic plexus. 



The gastric plexus accompanies the gastric artery along the lesser curva- 

 ture of the stomach. It receives branches from the coeliac plexus and from the 

 left vagus nerve. It sends branches of distribution to the stomach and to the 

 pyloric plexus. 



The hepatic plexus is the largesl offset from the coeliac plexus. It receives 

 branches from the coeliac plexus, the left vagus nerve and the righl phrenic 

 nerve. It distributes branch s to the pyloric plexus, and branches to the gastro- 

 duodenal plexus, which plexus divides into the righl gastro-epiploic plexus and 

 the pancreatico-duodenal plexus. It also sends branches to the cystic plexus. 



the right hepatic and the left hepal LC plexus. 



The splenic plexus accompanies the splenic artery, and receives branches
