23: Gallbladder

Structure & Macroscopic Appearance

The gallbladder is placed in the fossa for the gallbladder, a depression on the visceral surface of the liver. It has three parts:

  • The neck, which unites the gallbladder with the cystic duct. It is initially narrow and may have an 'S' shape
  • The body, the central part
  • The fundus, the wide sac distant from the neck.

Microscopic Structure

The gallbladder mucosa is covered with small ridges in a honeycomb pattern. The mucosa is simple columnar with a rich capillary network. There are no goblet cells as the gallbladder has a purely absorbing function.
