Pancreas in relation to stomach and duodenum
- A.
Posterior
- B.
Anterior
- C.
Posterior and superior
- D.
Posterior to stomach, anterior to duodenum
Correct Answer
D. Posterior to stomach, anterior to duodenumExplanation
The pancreas is located posterior to the stomach and anterior to the duodenum. It sits in the retroperitoneal space, running horizontally across the abdomen. Its position relative to the stomach and duodenum plays an important role in the digestive system, as it produces digestive enzymes that are secreted into the duodenum. It also has endocrine functions, such as producing insulin and glucagon, which are crucial for regulating blood glucose levels. This position is essential for the pancreas's interactions with surrounding organs in the digestive system.Rate this question:
-
- 5.
Pancreas lies between
- A.
Stomach and duodenal loop
- B.
Liver and stomach
- C.
Duodenal loop and splenic hilum
Correct Answer
C. Duodenal loop and splenic hilumExplanation
The pancreas lies between the duodenal loop and the splenic hilum. The duodenal loop is a part of the small intestine located near the stomach, while the splenic hilum is the area where the spleen is attached to the stomach. This positioning of the pancreas allows it to have close proximity to both the digestive system (duodenum) and the circulatory system (spleen).Rate this question:
-
- 6.
Which is true about the head of the pancreas, in relation to the vascular structures?
- A.
To the left of the SMV
- B.
Posterior to IVC
- C.
Caudal to portal vein
- D.
Anterior and lateral to GDA
Correct Answer
C. Caudal to portal veinExplanation
The head of the pancreas is located caudal to the portal vein. This means that it is positioned below the portal vein in relation to the vascular structures.Rate this question:
-
- 7.
The endocrine function of pancreas is
- A.
Production of insulin
- B.
Production and digestion of pancreatic juice
- C.
Production of glucagon
Correct Answer
A. Production of insulinExplanation
The endocrine function of the pancreas involves the production of insulin. Insulin is a hormone that helps regulate blood sugar levels by allowing cells to take in glucose from the bloodstream. Insufficient production of insulin can lead to diabetes, a condition characterized by high blood sugar levels. Therefore, the pancreas plays a crucial role in maintaining proper glucose metabolism through the production of insulin.Rate this question:
-
- 8.
Insulin
- A.
Produced by the pancreas
- B.
Causes glycogen formation
- C.
Allows cells within insulin receptors to take up glucose to decrease blood sugar
- D.
A and C
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
Insulin, which is produced by the pancreas, serves multiple functions in the body. One of its roles is to cause glycogen formation, which involves converting excess glucose into glycogen for storage. Additionally, insulin enables cells with insulin receptors to take up glucose from the bloodstream, thereby decreasing blood sugar levels. Therefore, the correct answer is "All of the above" because all the statements mentioned (insulin causing glycogen formation and allowing cells to take up glucose to decrease blood sugar) are true.Rate this question:

What is not true about lipase?
- A.
Breaks down fat
- B.
Elevated in pancreatitis
- C.
Remains increased for shorter period of time than amylase
- D.
Pancreatic enzyme
Correct Answer
C. Remains increased for shorter period of time than amylaseExplanation
Lipase is an enzyme that breaks down fat. It is elevated in pancreatitis, a condition characterized by inflammation of the pancreas. However, the statement that lipase remains increased for a shorter period of time than amylase is not true. In fact, lipase levels typically remain elevated for a longer duration than amylase levels in cases of pancreatitis. This is because lipase is more specific to pancreatic damage, while amylase can also be elevated in other conditions such as salivary gland inflammation.Rate this question:

Lies near the hilum of the spleen and upper pole of left kidney
- A.
Head
- B.
Body
- C.
Tail
Correct Answer
C. TailExplanation
The correct answer is "tail." The statement suggests that the structure being referred to is located near the hilum of the spleen and the upper pole of the left kidney. Among the options given, the tail of the spleen is the most appropriate answer as it is positioned in close proximity to these anatomical landmarks. The head and body of the spleen are not mentioned in the statement, making them less likely to be the correct answer.Rate this question:

- A.
Stomach
- B.
IVC
- C.
Lesser sac
- D.
Duodenum
Correct Answer
B. IVCExplanation
The correct answer is IVC because the pancreas is located behind the stomach, lesser sac, and duodenum. The IVC (inferior vena cava) is a large vein that carries deoxygenated blood from the lower body to the heart, and it is not positioned posterior to the pancreas.Rate this question:

- A.
SMA
- B.
Splenic artery
- C.
SMV
- D.
IVC
- E.
Aorta
Correct Answer
B. Splenic arteryExplanation
The pancreas is located in the abdominal cavity and is positioned in front of several structures. However, it is not anterior to the splenic artery. The splenic artery is a branch of the celiac trunk and runs along the upper border of the pancreas. Therefore, the pancreas is not anterior to the splenic artery.Rate this question:
-
- 16.
Which is not a branch of celiac axis?
- A.
Splenic vein
- B.
CHA
- C.
Splenic artery
- D.
Left gastric artery
Correct Answer
A. Splenic veinExplanation
The celiac axis is a major branch of the abdominal aorta that supplies blood to various organs in the abdomen. The branches of the celiac axis include the common hepatic artery (CHA), splenic artery, and left gastric artery. The splenic vein, on the other hand, is not a branch of the celiac axis. It is a vein that drains blood from the spleen and merges with the superior mesenteric vein to form the portal vein.Rate this question:

Homogeneous
- B.
Heterogeneous to the liver
- C.
Hypoechoic in children
- D.
A and C
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
The sonographic appearance of the pancreas can vary depending on different factors. It can appear homogeneous, meaning it has a uniform echo texture. It can also appear heterogeneous to the liver, meaning it has a different echo texture compared to the liver. In children, the pancreas is often hypoechoic, meaning it appears darker on the ultrasound image. Therefore, the correct answer is "all of the above" as the sonographic appearance of the pancreas can be homogeneous, heterogeneous to the liver, and hypoechoic in children.Rate this question:

Complete or partial duodenal atresia can be caused by
- A.
Agenesis
- B.
Annular pancreas
- C.
Pancreas divisum
- D.
Von hippel-lindau syndrome
Correct Answer
B. Annular pancreasExplanation
Annular pancreas is a condition where a band of pancreatic tissue forms a ring around the duodenum, causing a partial or complete blockage. This can lead to duodenal atresia, a congenital condition where the duodenum is narrowed or completely closed off. Agenesis refers to the absence or underdevelopment of a structure, but it is not directly related to duodenal atresia. Pancreas divisum is a common anatomical variation where the pancreatic ducts do not fuse properly, but it is not known to cause duodenal atresia. Von Hippel-Lindau syndrome is a genetic disorder that primarily affects blood vessel growth, and it is not associated with duodenal atresia. Therefore, annular pancreas is the most likely cause of duodenal atresia among the given options.Rate this question:

Which congenital pancreatic anomaly can cause diabetes in late stages?
- A.
Fibrocystic disease
- B.
Annular pancreas
- C.
Cystic fibrosis
- D.
Congenital cysts
Correct Answer
A. Fibrocystic diseaseExplanation
Fibrocystic disease is a congenital pancreatic anomaly that can cause diabetes in late stages. This condition is characterized by the presence of fibrosis and cysts in the pancreas, which can lead to impaired pancreatic function and insulin production. As the disease progresses, the pancreas becomes more damaged, resulting in the development of diabetes. Therefore, fibrocystic disease is the correct answer for the given question.Rate this question:
