What is superior duodenal flexure?

the flexure at the junction of the superior and descending parts of the duodenum.

What holds the duodenojejunal flexure?

The duodenojejunal flexure is surrounded by the suspensory muscle of the duodenum. It is retroperitoneal, so is less mobile than the jejunum that comes after it, helping to stabilise the jejunum. The duodenojejunal flexure lies in front of the left psoas major muscle, the left renal artery, and the left renal vein.

Where is hepatic flexure located?
