tn ni of the solar plexus, called aortic plexus ; (3) ganglia situated at the origin 

 of every artery from the aorta, which take the name of the aorta ; (4) branches 

 or plexuses from the ganglia, which take also the name of the artery and accom- 

 pany the same to its distribution. 



In view of the foregoing, you are prepared now to find, locate, explain, and 

 understand : 



1. Diaphragmatic artery, nerves, plexus, ganglion, and vein. 



2. Splenic artery, nerves, plexus, ganglion, and vein. 



3. Hepatic artery, nerves, plexus, ganglion, and vein. 



4. Gastric artery, nerves, plexus, ganglion, and vein. 



5. Suprarenal artery, nerves, plexus, ganglion, and vein. 



6. Renal artery, nerves, plexus, ganglion, and vein. 



7. Spermatic artery, nerves, plexus, ganglion, and vein. 



8. Ovarian arterv, nerves, plexus, ganglion, and vein. 



9. Superior nieseiitene arterv, nerves, plexus, ganglion, and vein. 

 10. Inferior mescnteric artery, nerves, plexus, ganglion, and vein.

 location of vessels. For solar and aortic plexuses see figure 1 86. 



Make special note : (i) The renal veins lie in front of their arteries, thereby 

 forming an exception to the rule governing the relation of arteries to veins. (2) 

 The left spermatic vein opens into the left renal vein, and this latter passes in front 

 of the aorta. (3) The right spermatic vein opens into the ascending vena cava just 

 b.-low the renal. (4) The ovarian reins follow the course of their homologues. 

 (5) Tlie spermatic arteries arise from the aorta below the renals, pass in front of 

 the ureter about opposite the bifurcation of the aorta. The ovarian take the 

 s une course. (6) The four lumbar arteries are analogous to the intercostals. 

 (7) Tlic iireterie arteries accompany the ureters ; they are branches of the common 

 iliac and superior vesicle. (8) The arteries to the vas defereiis, to the urachtts, and to 

 the ureter are branches of the superior vesicle. (9) ///( saera media, the smallest. 



Essential Points on the Sympathetic. You have traced out the branches 

 of the abdominal aorta, and I trust you now understand the principle under- 

 lying the distribution of visceral nerve-branches, from one abdominal prevertebral 

 plexus the solar plexus. We shall find in the pelvis, likewise, organs receiving 

 irteries ; these arteries will be accompanied by sympathetic nerves ; these nerves
