Quiz zum Vortrag
Which of the following is true regarding the development of the gallbladder?
- It develops as a secondary out-pouching of the liver bud and grows into the ventral mesentery.
- During the 3rd week, the hepatic diverticulum extends off the foregut and grows into the mesoderm of ventral mesentery and septum transversum to become the gallbladder.
- A dorsal and ventral gallbladder and cystic bud extend separately from nearby gut tube inferior to the stomach.
- It is derived from mesenchymal cells which are found between layers of the dorsal mesogastrium.
- The connection between the hepatic diverticulum and the gallbladder will become the hepatic duct.
Which of the following statements is true regarding the development of the pancreas?
- The rotation of the stomach brings the ventral pancreas posterior to the duodenum, allowing the dorsal and ventral pancreatic buds to fuse.
- The pancreas rotates independently of the stomach around week 3 allowing the dorsal and ventral buds to fuse.
- The pancreas develops as a secondary out-pouching from the hepatic diverticulum and grows into the ventral mesentery.
- The main pancreatic duct meets the duodenum through what was initially the dorsal pancreatic bud.
- The pancreas is derived from mesenchymal cells which are found between the layers of the dorsal mesogastrium.
Duodenal stenosis is most closely associated with which of the following?
- Migration of the ventral pancreas both anteriorly and posteriorly, leading to annular pancreas
- Hartman’s pouch
- Non-bilious emesis
- Pyloric stenosis
- Failure of migration of the dorsal pancreatic bud
Which of the following is not a characteristic biliary tree abnormality?
- Phrygian cap
