Aims: To study the various positions of vermiform appendix, and its relation to various diseases of the vermiform appendix, and average length and external diameter of the vermiform appendix. Materials & Methods: This study was conducted on 200 cases – 100 cadavers from the dissection laboratory with an age range of 50 – 90 years. The dissection was performed in the dissection hall of Smt. N.H.L. Municipal Medical College, Ahmedabad, B. J. Medical College, Ahmedabad, A.M.C.M.E.T. Medical College, Ahmedabad, and 100 cases from postmortum room of V. S. Hospital from August 2009 to December 2012.

In 8 cadaver’s variations regarding disposition of the left gastric, splenic and hepatic arteries also regarding the number of emitted arteries observed.
