B. kidney C. stomach A. liver D. pancreas Which structure is NOT supplied by the celiac trunk?
B. kidney C. stomach Which structure is NOT supplied by the celiac trunk?
Back to Board The celiac trunk supplies the caudal foregut structures like stomach, liver, proximal duodenum and upper pancreas. Kidney is not even a gut structure.
A. ventral C. medial B. dorsal D. lateral During gut development, which surface(s) give(s) rise to the greater curvature of the stomach?
B. dorsal C. medial During gut development, which surface(s) give(s) rise to the greater curvature of the stomach?
Back to Board The dorsal surface of the stomach in the embryo grows much faster than the ventral surface, so that it forms the greater curvature, while ventral forms the lesser.
A. anterior mesentery C. lesser omentum B. fusion fascia D. greater omentum During stomach development, the dorsal mesentery rotates to the anterior position to form what structure?
A. anterior mesentery D. greater omentum During stomach development, the dorsal mesentery rotates to the anterior position to form what structure?
Back to Board Greater omentum is named by its attachment to the greater curvature. The dorsal mesentery of the stomach, or dorsal mesogastrium, attaches to the developing greater curvature.
A. lungs C. bladder D. rectum B. small intestine Which of the following organs is directly covered by the greater omentum?
D. rectum B. small intestine Which of the following organs is directly covered by the greater omentum?
Back to Board The omental apron is a portion of the greater omentum that hangs down over the small bowel.
A. hepatic ligament C. right triangular ligament B. left triangular ligament D. falciform ligament Which of the following is NOT derived from the ventral mesentery?
A. hepatic ligament C. right triangular ligament Which of the following is NOT derived from the ventral mesentery?
Back to Board Never heard of a hepatic ligament - hepatoduodenal and hepatogastric ligaments are portions of the lesser omentum. Triangular ligaments are portions of the coronary.
A. liver and stomach C. stomach and spleen B. liver and spleen D. liver and kidney The lesser omentum connects what two organs?
A. liver and stomach C. stomach and spleen The lesser omentum connects what two organs?
Back to Board The two parts of lesser omentum are the hepatogastric and hepatoduodenal ligaments, connecting liver to the stomach and the first part of the duodenum.
D. dorsal C. inferior B. superior A. ventral Which pancreatic bud grows within the ventral mesentery?
D. dorsal A. ventral Which pancreatic bud grows within the ventral mesentery?
Back to Board With a name like “ventral”, it seems like the ventral pancreatic bud would grow into the ventral mesentery.
A. thoracic duct C. hepatic duct B. common bile duct D. cystic duct After rotation of the duodenum, what opening is found posteromedially on the adult duodenum?
D. cystic duct B. common bile duct After rotation of the duodenum, what opening is found posteromedially on the adult duodenum?
Back to Board After rotation of the duodenum, the common bile duct opens into the posteromedial wall of the 2nd part of the duodenum.
A. the appendix D. superior mesenteric vein B. celiac artery C. superior mesenteric artery What structure serves as the axis of midgut rotation?
C. superior mesenteric vein D. superior mesenteric artery What structure serves as the axis of midgut rotation?
Back to Board The artery of the midgut, the superior mesenteric, serves as the axis for its 270 degree rotation counterclockwise.
A. kidneys and spleen C. liver and kidneys B. stomach and spleen D. liver and stomach Umbilical herniation is caused by the rapid development of what organs?
C. liver and kidneys D. liver and stomach Umbilical herniation is caused by the rapid development of what organs?
Back to Board During development, the liver and kidneys are very prominent structures that crowd the gut out of the abdominal cavity and into the body stalk.
A. superior mesenteric artery C. bile duct D. vitelline duct B. cystic duct What separates the cranial limb from the caudal limb of the midgut?
D. vitelline duct B. cystic duct What separates the cranial limb from the caudal limb of the midgut?
Back to Board The viteline duct separates the cranial and caudal limbs of the midgut, and also serves to tether the midgut to the umbilicus.
A. descending colon C. cecum B. ascending colon D. appendix Which of the following is NOT included in the caudal midgut?
A. descending colon D. appendix Which of the following is NOT included in the caudal midgut?
Back to Board The dividing line between midgut and hindgut is along the transverse colon 1/3rd proximal to the splenic flexure - so descending colon is hindgut.
A. kidneys C. ascending colon B. pancreas D. duodenum Which organ(s) is/are NOT secondarily retroperitoneal?
A. kidneys C. ascending colon Which organ(s) is/are NOT secondarily retroperitoneal?
Back to Board To be secondarily retroperitoneal, you have to be peritonealized at some time. Kidney is always behind the peritoneum, and so is primarily retroperitoneal.
B. descending colon C. transverse colon A. rectum D. sigmoid colon Which structure receives its blood supply from both the inferior mesenteric artery and the internal iliac artery?
D. sigmoid colon A. rectum Which structure receives its blood supply from both the inferior mesenteric artery and the internal iliac artery?
Back to Board The rectum receives a superior rectal branch from the inferior mesenteric artery as well as middle and inferior rectal branches from the internal iliac artery.
Sorry, that is incorrect!
