Introduction
This section of notes gives an overview of Gall Bladder and hillary tree 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 duodenum 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. There are several opinions as to whether the duct has a solid phase or remains patent throughout development.[1][2]

Embryonic Development
Early embryonic gall bladder (Carnegie stage 13, Week 4)
Late embryonic gall bladder (Carnegie stage 22, Week 8)
Abnormalities
Infections
These mainly relate to postnatal infections. Recent studies in the mouse have identified that gastrointestinal tract listeria infections can relocate to the gall bladder and reside there, leading to later reinfection of the gastrointestinal tract.
