Introduction

Early embryonic gall bladder (Carnegie stage 13, Week 4)

This section of notes gives an overview of Gall Bladder development, histology and abnormalities associated with the biliary system. In the adult, the gall bladder is a site of bile salt storage and concentration, to then be released into the small intestine where they act to solubilize dietary lipids by their detergent effect. Bile salts are a cholesterol derivative (breakdown product).

The transverse septum differentiates to form the hepatic diverticulum and the hepatic primordium, these two structures together will go on to form different components of the mature liver and gall bladder.

The hepatic diverticulum divides into two parts: pars hepatica (larger cranial part, primordium of the liver) and pars cystica (smaller ventral invagination, primordium of gall bladder).

The pars cystica vacuolates and expands, the stalk becoming the cystic duct. This structure is initially hollow, then solid (by proliferation of epithelial lining), and then recanalized occurs by vacuolation of this expanded epithelium. (some text above modified from Bani-Hani KE., 2005)
