Bowel anatomical model MP1730

for teaching

This 3D printed small loop of jejunum illustrates the arterial arcades in the mesentery, featuring many long straight vasa rectae and fewer vascular arcades compared to the ileum. The mesentery has been dissected to reveal the fat and visceral peritoneum, along with lymph nodes (grey-light green), which are prominent near the root of the mesentery and larger vessels. Mesenteric Fat and Vessels Typically, the fat in the jejunal mesentery does not extend to the mesenteric border, allowing a clear view of the long straight vessels. In this specimen, however, a patient with a larger amount of abdominal fat shows fat extending further toward the mesenteric border, partially obscuring this window. Jejunal Mucosa A small segment of the jejunum has been opened to display the mucosal folds, which are more numerous and smaller than in the ileum, providing a detailed view of the internal structure of the bowel.
