The mesentery is a fold of membranous tissue that arises from the posterior wall of the peritoneal cavity and attaches to the intestinal tract.Within it are the arteries and veins that supply the intestine.uring mobilization of the small intestinal mesentery from the posterior abdominal wall, this fold is incised, allowing access to the interface between the small intestinal mesentery and the retroperitoneum.
Mesenchyme is a form of loose connective tissue that develops within an embryo. It consists of a ground substance, made up of proteins and water and being gelatinous in texture, that protects and supports the cells and reticular fibers within.d. The mesenchymal cells arise largely from the mesoderm as the embryo continues to differentiate. Mesenchyme is considered a form of reticular connective tissue because it contains reticular fibers, which are fibers made up of a certain type of collagen known as type III collagen.
