INTRODUCTION: The gall bladder (GB) is a storage reservoir that allows bile acids to be delivered in a high concentration. The quadrate (QL) and caudate lobes (CL) are functional parts of the liver. The knowledge of the gross and developmental anatomy of GB and CL and QL of liver is important for surgeons who operate in this region. The present study was conducted to examine the developmental sequence and morphometry of the GB, and CL and QL of liver. MATERIALS AND METHODS: In the present cross sectional study the parameters measured were length of GB from the neck to the lowest point on the fundus, and the length and width of QL and CL measured at the midpoint. The data was analyzed statistically and the various parameters were correlated using Pearson's correlation. RESULTS: There was a statistically significant correlation indicating that the growth of GB, QL and CL was proportional to the gestational age (GA). The variations in the morphology of the GB were also noted. In two specimens it was found that the GB was embedded partially in the substance of the liver and failed to reach the inferior border of the liver. CONCLUSION: The regression equations calculated in the study provide a tool to estimate the lengths of GB, QL and CL prenatally.
