Anterior branch of renal artery
Blood vessels · Latin: Ramus anterior arteriae renalis
Before reaching the hilus of the kidney, each artery divides into four or five branches.
The anterior branches (the upper, middle, lower and apical segmental arteries) lie between the renal vein and ureter, the vein being in front, the ureter behind.
