A patient was diagnosed with bleeding ulcer of the lesser curvature of the stomach. Which artery is most likely involved? 
Gastroduodenal
Left gastric
Left gastro-omental (epiploic)
Right gastro-omental (epiploic)
Short gastrics
Which is a derivative of the dorsal mesogastrium? 
Falciform ligament
Hepatoduodenal ligament
Hepatogastric ligament
Greater omentum
Lesser omentum
The spleen: 
Develops in the dorsal mesogastrium
Develops in the ventral mesogastrium
Develops in both the dorsal and ventral mesogastria
Is always retroperitoneal
Becomes retroperitoneal during its development
During a full workup on a 2-month-old infant with a history of intermittent gastrointestinal pain and vomiting, physicians discovered that the cause was lack of emptying of the stomach. They immediately suspected that the cause was a spasmodic contraction of which of the following parts of the stomach? 
cardiac notch
fundus
lesser curvature
pylorus
rugae
In order to do a vagotomy (section of vagal nerve trunks) to reduce the secretion of acid by cells of the stomach mucosa in patients with peptic ulcers, one needs to cut the gastric branches and retain vagal innervation to other abdominal organs. Where would a surgeon look for these branches in relation to the stomach? 
along the gastroepiploic vessels
along the greater curvature
along the lesser curvature
in the base of the omental apron
in the gastrocolic ligament
While performing a splenectomy (removal of the spleen) following an automobile accident, the surgeons were especially attentive to locate and preserve the tail of the pancreas which is closely associated with the spleen. This they found in the: 
gastrocolic ligament
gastrosplenic ligament
phrenicocolic ligament
splenorenal ligament
transverse mesocolon
Which of the following structures does not lie at least partially in the retroperitoneum? 
adrenal gland
duodenum
kidney
pancreas
spleen
Which ligament is a derivative of the dorsal mesogastrium?
Coronary
Falciform
Hepatoduodenal
Hepatogastric
Gastrocolic
A 60-year-old male executive who had a history of a chronic duodenal ulcer was admitted to the ER exhibiting signs of a severe internal hemorrhage. He was quickly diagnosed with perforation of the posterior wall of the first part of the duodenum and erosion of an artery behind it by the gastric expellent. The artery is most likely the:
Common hepatic
Gastroduodenal
Left gastric
Proper hepatic
Superior mesenteric
A twenty-year-old woman was broad-sided on the driver side by an SUV and was taken to the hospital emergency room. Examination showed low blood pressure and tenderness on the left mid-axillary line. Also, a large swelling was felt protruding downward and medially below the left costal margin. X-rays revealed that her 9th and 10th ribs were fractured near their angles on the left side. The abdominal organ most likely to be injured by the fracture is:
Descending colon
Left kidney
Pancreas
Spleen
Stomach
You are observing an operation to remove the left suprarenal gland. To expose the gland the surgeon mobilizes the descending colon by cutting along its lateral attachment to the body wall and dissecting medialward in the fusion fascia behind it. Suddenly the operative field is filled with blood. The surgeon realizes he has failed to cut a mesenteric attachment between the left colic flexure and another organ. As a result of the traction, the surface of the organ tore. Which organ was injured?
Duodenum
Kidney
Liver
Spleen
Suprarenal gland
A patient presented with a swollen spleen, which protruded medially toward the umbilicus in the abdomen. A vertical and downward expansion of the spleen was resisted by the:
Tail of the pancreas
Left colic flexure
Left kidney
Left renal artery
Stomach
During emergency surgery, it was found that a chronic gastric ulcer had perforated the posterior wall of the stomach and eroded a large artery running immediately posterior to the stomach. The artery is the:
Gastroduodenal
Common hepatic
Left gastroepiploic
Splenic
Superior mesenteric
The spleen contacts all of the following organs EXCEPT:
Jejunum
Kidney
Left colic flexure
Tail of the pancreas
Stomach
Which is not a boundary of the epiploic (omental) foramen?
Aorta
Caudate lobe of the liver
First part of the duodenum
Hepatoduodenal ligament
In order to approach the area posterior to the stomach, a surgeon decided to go through the lesser omentum. Before incising the mesentery she was careful to find and preserve a nerve lying in the upper portion of the hepatogastric ligament, i.e., the
Celiac branch of the anterior vagal trunk
Celiac branch of the posterior vagal trunk
Greater splanchnic branch to the right suprarenal gland
Hepatic branch of the anterior vagal trunk
Hepatic branch of the posterior vagal trunk
Which of the following is NOT in contact with the spleen?
Colon
Diaphragm
Duodenum
Pancreas
Stomach
The fundus of the stomach receives its arterial supply from the:
Common hepatic
Inferior phrenic
Left gastroepiploic
Right gastric
Splenic
During an emergency splenectomy, the surgeon accidentally tore the gastrosplenic ligament and its contents. The artery (ies) likely to be damaged in this event is (are) the:
Left gastric
Splenic
Short gastric
Middle colic
Caudal pancreatic
While performing emergency surgery to control hemorrhage brought on by arterial erosion caused by a duodenal ulcer, surgeons ligated the badly damaged gastroduodenal artery near its origin, which affected all of its branches as well. Assuming "average anatomy", in which of the following arteries would blood now flow in retrograde fashion (backwards) from collateral sources?
Left hepatic
Right gastroepiploic
Short gastric
Left gastric
Omental branches
