Abstract:

Gall bladder is a small pocket like organ for the storage and concentration of bile. Gall bladder was collected from 24 guinea pigs of four different postnatal ages namely 0-2 weeks, 2-8 weeks, 8-16 weeks and 16-32 weeks of age with six animals each irrespective of sex were collected from the Department of Laboratory Animal Medicine, Madhavaram Milk Colony, Chennai with Ethical committee approval. Gall bladder was completely seen on the visceral surface of the liver but the body of the gall bladder was seen on the parietal surface. It was found in the gall bladder fossa located between the right medial lobe and quadrate lobe of the liver and was well adapted to the gall bladder fossa of the liver. But it was extended slightly outside the liver border. At the neck region of the gall bladder, it had a swelling which continued as cystic duct. The gall bladder with full secretion was round to elongate in shape. It was transparent in colour. When filled with bile, it had light green colouration. It was soft to touch and had smooth surface. The left hepatic duct was formed by the hepatic ducts of quadrate lobe, left lateral lobe and left medial lobe. The right hepatic duct was formed by the hepatic ducts of caudate lobe, right lateral lobe and right medial lobe. The cystic duct first joined with the left hepatic duct and then with the right hepatic duct and formed common bile duct. The common bile duct had an ampullary dilation when it opened to the duodenum. The gall bladder attached to the right medial lobe by a ligament. A small ligament was found connecting the gall bladder to the quadrate lobe.
