It is a vestigeal organ in humans. This study was done 50 adult cadavers and spontaneously aborted fetal specimens. The anatomical variations were photographed, tabulated and compared with previous studies. Bacterial infection of appendix known as appendicitis is an emergency condition in all age groups. This is treated by removal of it known as appendicectomy. Detailed knowledge about the normal and variant anatomy is important for the surgeons during the surgery. The anatomical knowledge is also useful to the radiologist for diagnosing the appendicular artery in angiograms. KEY WORDS: Vermiform Appendix, Vestigial, Appendicectomy.

The appendicular artery runs runs behind the terminal ileum and enters the mesoappendix usually up to the tip but sometime it lies on the appendicular wall if the mesoappendix is short. The base of the appendix has anastomosis from the recurrent branch of appendicular artery and a branch from the posterior caecal artery. Accessory appendicular arteries may arise from the superior division of ileocolic artery or posterior caecal branch or directly from the ileocolic artery [1, 2]. Inflammation of appendix is known as appendi- citis and usually it is an acute condition affect- ing the young adults, common cause of acute abdomen. Since the appendicular artery is an end artery and also it’s close proximity with the appendicular makes it more susceprible to The appendix is a narrow tube like structure lying in the right iliac fossa. It is part of large intestine and its base is attached to the poste- rolateral surface of the caecum just below ileocaecal junction, the tip is free and it may be present in retrocaecal, subcaecal, pre/post ileal or pelvic positions. It resembles worms and that’s why known as vermiform appendix. The mesentery of appendix is known as mesoappen- dix and the appendicular artery runs in it. The appendix develops from the midgut of the intestinal loop so its arterial supply is received from superior mesenteric artery. Superior mesenteric artery arises from the abdominal aorta at the level of first lumbar vertebra. The appendicular artery arises from the inferior division of ileocolic artery which is the terminal
