Which structure is NOT supplied by the celiac trunk?
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.

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.

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.
