Question
Which of the following best describes the location of the duodenum?Group of answer choicesAnterior to the pancreasPosterior to the left colic flexureInfraperitonealInferior to the liver
Solution
The duodenum is best described as being anterior to the pancreas. Here's why:
-
The duodenum is the first part of the small intestine, which is located in the upper abdomen, and it is positioned close to the pancreas.
-
The term "anterior" in anatomy refers to the front, or forward-facing side of the body. So, saying that the duodenum is anterior to the pancreas means that it is located in front of the pancreas.
-
The other options are not accurate. The duodenum is not posterior to the left colic flexure, which is a part of the large intestine, not the small intestine. It is not infraperitoneal; it is actually a retroperitoneal organ, which means it is located behind the peritoneum, the lining of the abdominal cavity. And while the duodenum is somewhat inferior (below) to the liver, this description is not as precise as saying it is anterior to the pancreas.
