The suspensory muscle of the duodenum is the proper name of what is commonly known as the ligament of Treitz, and it refers to tissue that connects the duodenum of the small intestines to the diaphragm. It is also known as the suspensory ligament of the duodenum. In anatomy of the digestive system, the duodenum is a hollow jointed tube connecting the stomach to the jejunum. ...

Structure

It arises from the connective tissue around the stems of the celiac trunk and superior mesenteric artery and inserts into the third and fourth portions of the duodenum and frequently into the duodenojejunal (DJ) flexure (between the duodenum and the jejunum) as well. Composed of a slip of skeletal muscle from the right crus of the diaphragm and a fibromuscular band of smooth muscle from the third and fourth parts of the duodenum, when it contracts, it has the effect of opening the DJ flexure and permitting the flow of chyme.
