Answer: A: Greater sac of stomach forms anterior border 
Explanation: Ans. A Greater sac of stomach forms anterior borderRef: Clinical Anatomy, 11th ed. pg. 151* The suprarenal glands cap the upper poles of the kidneys and lie against the crura of the diaphragm.* The left is related anteriorly to the stomach across the lesser sac, the right lies behind the right lobe of the liver and tucks medially behind the inferior vena cava.* Posteriorly both kidney and adrenals are guarded by psoas major muscle.* Spleen is anterolateral to left adrenal gland.Extra Mile* Each gland, although weighing only 4 to 6 gm, has three arteries supplying it:# SUPERIOR: A branch from the phrenic artery;# MIDDLE: A direct branch from the aorta;# INFERIOR: A branch from the renal artery.* VENOUS DRAINAGE:# IVC on RIGHT# RENAL VEIN on the LEFT.# The stubby right suprarenal vein, coming directly from the inferior vena cava, presents the most dangerous feature in performing an adrenalectomy.
