Introduction: Appendix is connected by a short mesoappendix to the lower part posterior (left)layer of the ileal mesentery. This fold is usually triangular, extending almost to the appendicular tip along the whole tube. The mesoappendix has a free border which carries the blood supply to the organ, by the appendicular artery; a branch from the ileocolic artery. This study has been undertaken to investigate certain anatomical features such as the extent of the mesoappendix

Material and method: This study was conducted on 91 cases from the dissection laboratory with an age range of 50-90 years, The dissection was performed in dissection hall of various medical collage of Ahmedabad.

Result: In present study mesoappendix was not reach at tip of vermiform appendix in 50cases (54.95%) and mesoappendix is reach at tip of vermiform appendix in 65cases (45.05%).

Conclusion: Appendix is supplied by aend artery which is one of cause of occurrence of appendicitis. Appendicular artery which is branch of inferior division of iliocolic artery which goes through appendix along mesoappendix. In the present study variation in length of mesoappendix was seen from which we can understand about blood supply and vascularity of appendix. The appendicular artery runs first in the free margin of the mesoappendix and then.

close to the appendicular wall, where it may be thrombosed in appendicitis, leading to ischemic necrosis and perhaps rupture of the appendix, there is no collateral circulation for appendicular artery is an end artery.
