Accepted Answer

The answer of What two vessels can commonly be found...

Question 8

In the figure below of an axial CT of the abdomen,which arrow points to the splenic vein?

A) A
B) B
C) C
D) D

Accepted Answer

The arrow labeled B points to the splenic vein, which is coming from the spleen and joining with the superior mesenteric vein to form the portal vein. Arrows A and C are pointing to the aorta and inferior vena cava, respectively. Arrow D is pointing to the right kidney.

Question 9

Which vessel supplies blood to the transverse colon?
A) Celiac trunk
B) Superior mesenteric artery
C) Inferior mesenteric artery
D) Suprarenal artery

Accepted Answer

The inferior mesenteric artery supplies the descending colon, sigmoid colon, and transverse colon.

Question 10

What are the small fat-filled sacs of omentum called that are found on the outer
Surface of the large intestine?
A) Haustra
B) Taenia coli
C) Vermiform appendix
D) Epiploic appendages

Accepted Answer

The epiploic appendages are small fat-filled sacs of omentum that are found on the outer surface of the large intestine, and are also known as the appendices epiploicae. The other options (A, B, and C) are all structures that are located within the large intestine, but not on its outer surface.

Question 11

Which structures join together to form the renal pelvis?
A) Renal pyramids
B) Calyces
C) Nephrons
D) Renal cortices

Accepted Answer

The calyces join together to form the renal pelvis. The renal pyramids and the renal cortices are part of the kidney, but they do not directly contribute to the formation of the renal pelvis. Nephrons are the functional unit of the kidney and are not involved in the formation of the renal pelvis.

Question 12

Which organ is retroperitoneal?
A) Pancreas
B) Gallbladder
C) Spleen
D) Stomach

Accepted Answer

The pancreas is located towards the back of the abdominal cavity, behind the stomach, and is considered retroperitoneal. B) Gallbladder, C) Spleen, and D) Stomach are not retroperitoneal organs.

Question 13

Which of the following is a ligament of the lesser omentum?
A) Hepatoduodenal
B) Gastrocolic
C) Gastrophrenic
D) Falciform

Accepted Answer

The hepatoduodenal ligament is one of the two ligaments that make up the lesser omentum. The gastrocolic and gastrophrenic ligaments are both part of the greater omentum, while the falciform ligament is a separate structure that divides the left and right lobes of the liver.

Question 14

Where is Morison's pouch located?
A) Right subphrenic space
B) Right subhepatic space
C) Left subphrenic space
D) Left subhepatic space

Accepted Answer

Morison's pouch, also known as the hepatorenal recess, is located in the right subhepatic space, between the liver and the right kidney.

Question 15

Which structure lines the abdominal wall?
A) Peritoneum
B) Mesentery
C) Omentum
D) Pleura

Accepted Answer

The peritoneum lines the abdominal wall and covers many of the organs located in the abdominal cavity. The mesentery and omentum are both folds of the peritoneum that support and connect different organs in the abdomen. The pleura, on the other hand, lines the thoracic cavity and covers the lungs.

Question 16

The margins of the bare area of the liver are formed by the:
A) falciform ligament.
B) ligamentum teres.
C) coronary ligaments.
D) epiploic foramen.

Accepted Answer

The coronary ligaments form the margins of the bare area of the liver, which is the part of the liver not covered by peritoneum.

Question 17

Which section of the small intestine is retroperitoneal?
A) Duodenum
B) Jejunum
C) Ileum
D) Cecum

Accepted Answer

The duodenum is the first section of the small intestine and is retroperitoneal, meaning it is located behind the peritoneum (the membrane that lines the abdominal cavity). The jejunum and ileum are intraperitoneal, meaning they are located within the peritoneal cavity. The cecum is actually part of the large intestine, not the small intestine.

Question 18

As the interlobar arteries curve over the renal pyramids they become the _____ arteries.
A) apical
B) arcuate
C) interlobular
D) segmental

Accepted Answer

The interlobar arteries curve over the renal pyramids and become the arcuate arteries, which run parallel to the surface of the kidney, creating an arc-shaped pattern.

Question 19

The common bile duct is formed by the union of the _____ ducts.
A) common hepatic and pancreatic
B) cystic and pancreatic
C) common hepatic and cystic
D) cystic and porta hepatic

Accepted Answer

The common bile duct is formed by the union of the common hepatic duct and the cystic duct.

Question 20

In the figure below of an axial CT of the abdomen,which arrow points to Morison's pouch?

A) A
B) B
C) C
D) D

Accepted Answer

Morison's pouch is located between the liver and the right kidney, which is indicated by the arrow pointing towards the space between these two structures. Arrow B points towards this location, therefore it is the correct answer. Arrow A points towards the spleen, Arrow C points towards the pancreas, and Arrow D points towards the ascending colon, all of which are not related to Morison's pouch.
