BLOCK 2 ANATOMY 2: BILIARY DUCTS AND GALLBLADDER

Clinical Correlations: Cholecystitis produces discomfort in the right upper quadrant or epigastrium; may cause irritation of the subdiaphragmatic parietal peritoneum, which is supplied in part by the phrenic nerve (C3, 4, 5); this may give rise to referred pain over the shoulder, because the skin in this area is supplied by the supraclavicular nerves (C3 and 4).

inflammation of the gallbladder, may have stones or may not have stones

Nerve Supply Sympathetic and parasympathetic vagal fibers form the celiac plexus, right phrenic nerve. • The gallbladder contracts in response to the hormone cholecystokinin, which is produced by the mucous membrane of the duodenum on the arrival of fatty food from the stomach.

** Phrenic Nerve is important

Introduction: Biliary tree The biliary tree is a system of vessels that directs these secretions from the liver, gallbladder and pancreas through a series of ducts into the duodenum. Gall bladderIt is a gastrointestinal organ located within the right hypochondrial region of the abdomen. This intraperitoneal, pear-shaped sac lies within a fossa formed between the inferior aspects of the right and quadrate lobes of the liver. The primary function of the gallbladder is to concentrate and store bile which is produced by the liver.
