MESOJEJUNUM Meaning and
Definition
-
The mesojejunum is a term used in anatomy to describe a specific portion of the abdomen, specifically the peritoneum. The word mesojejunum is derived from the Greek terms "meso," meaning "middle," and "jejunum," which refers to the second part of the small intestine.
The mesojejunum is a fold of peritoneum that connects and supports the jejunum, a long, coiled segment of the small intestine. It extends from the ligament of Treitz, where the jejunum starts, to the point where the jejunum transitions into the ileum.
This peritoneal fold plays a crucial role in maintaining the position and stability of the jejunum within the abdominal cavity. It contains various structures, such as blood vessels, lymphatics, and nerves, which supply and innervate the jejunum.
The mesojejunum serves as a protective covering for the jejunum and helps to anchor it in place. It also allows for mobility and flexibility of the small intestine, enabling it to adapt to changes in the body's position and movements.
Understanding the anatomy and function of the mesojejunum is important in medical contexts, as it provides insights into the diagnostic, surgical, and pathological considerations related to the jejunum and the broader digestive system.

Etymology of MESOJEJUNUM
The word "mesojejunum" is a medical term that combines two roots: "meso-" and "jejunum".
The prefix "meso-" comes from the Greek word "mesos", meaning "middle" or "between". It is commonly used in medical terminology to indicate a structure or organ that is in the middle or intermediate position.
"Jejunum" is derived from the Latin word "jejunus", which means "empty" or "fasting". It refers to the part of the small intestine that follows the duodenum and precedes the ileum. The jejunum is usually empty or appears relatively empty during fasting or surgery, which is how it got its name.
Therefore, "mesojejunum" refers to the fold of peritoneum that attaches the middle portion of the small intestine, specifically the jejunum, to the back wall of the abdomen.
