Parts of gallbladder

The gallbladder has the following three anatomical parts

  • Fundus - wide distal rounded end of the gallbladder that points anteroinferior; it is found next to the inferior border of the liver, projecting on the anterior abdominal wall at the mid-clavicular line level at the site where the lateral margin of the rectus abdominis muscle crosses the right costal arch;
  • Body - the largest part; it lies in the fossa for the gallbladder;
  • Neck - the narrow proximal part that tapers and becomes continues with the cystic duct (Read more!); the distal part of the neck contains oblique ridges that are continuous with the spiral valves of Heister (mucosal folds found within the mucosa of the cystic duct).

Note: Most people have an outpouching or diverticulum within the neck of the gallbladder called Hartmann's Pouch. It is a frequent but inconsistent feature. However, it is an important feature as Hartmann's Pouch is a common location for gallstones to become trapped and, as a result, cause cholestasis.
