A mesentery is a double layer of peritoneum that encloses the intestines and attaches them to the posterior abdominal wall 3. The term was originally only used to refer to the double layer of peritoneum that suspends the jejunum and ileum, but its meaning has been widened.
Mesenteries include:
small bowel mesentery (mesentery proper): suspends the jejunum and the ileum
mesoappendix: peritoneum of the vermiform appendix
transverse mesocolon: peritoneum of the transverse colon
sigmoid mesocolon: peritoneum of the sigmoid colon
