Anatomy Bones and Muscles · MU Pleven

59. Intra- and extrahepatal biliary ducts. Gall bladder.

Covers the pancreas first, including its endocrine and exocrine roles, its head, body and tail, the main and accessory pancreatic ducts, neighbouring structures, blood, lymph and nerve supply, and the histology of acinar cells and islets. It then describes the intrahepatic and extrahepatic bile ducts, with the extrahepatic duct divided into four parts, and ends with the gallbladder's location, structure, arterial, venous and nerve supply.

PANCREAS

  • Secondary retroperitoneal organ
  • It is soft mixed gland :
  • endocrine – releases hormones into the blood. One of the important hormones it releases is insulin.
  • Exocrine – produces pancreatic juice → flows into the duodenum that contains different enzyme.
  • Extends from concavity of the duodenum (at right side) to the spleen (at left side)
  • It lies in the epigastric and left hypochondrial regions ( Its neck at level of L1)

Parts:

  1. 1 Head of pancreas (caput pancreatis) – the large and rounded part of the pancreas – is located in front of the body of vertebra L2 within the concavity of the duodenum
  2. 1.1 Pancreatic notch (incisura pancreatis) – an notch on the inferior aspect of the pancreas between its head and body
  3. 1.2 Uncinate process (processus uncinatus) – a extension of the head of the pancreas – passes behind the superior mesenteric vessels
  4. 2 Body of pancreas (corpus pancreatis) – the narrower and longer part of the pancreas – courses horizontally to the left side over the large vessels
  5. 2.1 Omental eminence (tuber omentale) – a ventral prominence elevated by the abdominal aorta
  6. 3 Tail of pancreas (cauda pancreatis) – points towards the spleen, located intraperitoneally
