Anatomy of Gall bladder

1. Anatomy of Gall bladder and Biliary tree

2. Gall bladder Length: 7-10 cm Maximum breadth: 3 cm Capacity: 30-50 ml Location: Pear shaped sac situated in a non peritoneal fossa on the undersurface of the right lobe of liver extends from the right end of porta hepatis to the inferior border of liver . Lining epithelium: simple collumner epithelium. Parts of gall bladder

3. Blood Supply Arterial supply

4. Venous drainage: cystic vein drains into portal vein. Lymphatic Drainage:Cystic → node hepatic and celiac. Innervation: 1. sympathetic: T6-T9 through celiac plexuse . 2.Parasympathetic; Right vagus trough hepatic plexus.

5. Embryology Genesis of gall bladder and cystic duct from distal portion of hepatic diverticulum(pars cystica) By end of 4th week of intrauterine life, cystic duct and gall bladder primordium produced from pars cystica of hepatic diverticulum. By 5th week all elements of biliary tree recognizable.
