The mesentery is a supportive tissue that is rooted into the intestines while the omentum is a portion of fat-derived supportive tissue that plays a protective role during inflammation or infection and it hangs in front of the intestines. This is the key difference between the omentum and the mesentery.
Is the greater omentum the mesentery?
The mesenteries are multilayered folds of peritoneum that enclose a layer of fat and convey blood vessels, nerves, and lymphatics to the intraperitoneal abdominal viscera. The greater omentum is a 4-layered fold of peritoneum that extends down from the stomach, covering much of the colon and small bowel.
Is omentum and peritoneal the same?
The main difference between omentum and peritoneum is that omentum is an abdominal structure formed from the visceral peritoneum with a structure similar to the mesentery whereas peritoneum is the thin, serosal membrane, which lines the abdominal and pelvic cavities, covering most of the viscera.
