The mesentery contains an extensive lymphatic network of approximately 150 lymph nodes which are arranged into three stations: the juxta-intestinal nodes (found along peripheral arterial arcades)

Leonardo da Vinci depicted it as one contiguous organ, and it remained that way for centuries until 1885, when Sir Frederick Treves' findings presented the mesentery as fragmented amongst the small intestine, transverse colon and sigmoid colon. The research of Dr.

A type of connecting peritoneum between the intestinal and reproductive tracts to the abdominal wall. They are the expansive, double-layered serosal folds between the visceral peritoneum and the parietal peritoneum. They contain the blood vessels, lymphatics and veres supplying their respective organs.

What type of connective tissue is mesentery?

The mesentery is covered on both sides by mesothelium and has a core of loose connective tissue containing fat, lymph nodes, blood vessels, and nerves, which pass to and from viscera.

What is the mesentery of the small intestine?

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.
