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