ARTERIES. 



Paired Branches. 



The inferior phrenic runs behind (right side) the inferior 

 vena cava or (left side) oesophagus and across the crus to the 

 inferior surface of the diaphragm, dividing into two branches, 

 internal and external ; a branch (superior capsular) often sup- 

 plies the suprarenal body. The lumbar are four (or five) 

 branches on each side which cross the spine under the Psoas 

 and pass forward between the Transversalis and Internal 

 oblique; their branches are dorsal and muscular. The middle 

 suprarenal (capsular) runs above the renal artery to the supra- 

 renal gland. The superior and inferior suprarenal arise from 

 the inferior phrenic and renal respectively. [839] 



The renal arises high up and runs almost transversely be- 

 hind the pancreas, and (right side) inferior vena cava and 

 duodenum, to the hilus of the kidney, which it enters, dividing 

 into three branches; of these one passes behind the pelvis of 

 the ureter and two in front. Branches; inferior suprarenal, to 

 the suprarenal body; ureteral, to the ureter; peri-renal, to the 

 kidney capsule ; glandular, to renal and lumbar glands. [842] 



The spermatic arises just below the renal and descends over 

 the external iliac artery and the ureter to the internal abdom- 

 inal ring, then traverses the inguinal canal and descends to 

 the scrotum. Branches; ureteral to the ureter; cremasteric, 

 to the Cremaster; ependymal, to the epididymis; and testicu- 

 lar to the testicle. The ovarian has the same origin and earlier 

 course as the spermatic, but turns inward near the internal 

 abdominal ring, descends into the pelvis, and runs in the broad 

 ligament. Branches; ureteral to the ureter; tubal, to the 

 Fallopian tube ; ligamentous, to the round ligament ; ovarian, 

 to the ovary ; and uterine, to the uterus. [842] 



Unpaired Branches. 



The middle sacral arises just above the bifurcation of the 

 aorta and descends in the midline, upon the sacrum and coccyx, 

 to the tip of the latter. [841]
