The extra hepatic biliary apparatus usually shows anatomical variations. These variations are not noticed normally. They are commonly encountered during surgery or any radiological investigation. So the present study was carried out to determine the external morphology of gall bladder in 40 liver and gallbladder specimens obtained from 10% formalin fixed cadavers from dissection hall. In present study, most common shape of gall bladder was Pear shape (67.5%), the average length and max. transverse diameter were found to be 6.75cm and 3.05cm respectively. Maximum length of gall bladder range between 4.5 – 8 cm,out of which 52.5 % gall bladder range between 6.6–8 cm. Maximum transverse diameter of gallbladder range between 2–5 cm, out of which, 45% of gall bladder range between 2–3 cm.
