9 sie 2024 · The duodenum is a C-shaped organ connected to the stomach that plays a key role in digestion. Diseases affecting the duodenum include celiac disease, Crohn's disease, and duodenal ulcers. Inflammation of the duodenum (duodenitis) can be caused by infections, heavy tobacco use, and the use of NSAIDs.
17 lip 2023 · The proximal segment of the duodenum is supplied by the gastroduodenal artery and its branches which include the superior pancreaticoduodenal artery. The distal segment of the duodenum is supplied by the superior mesenteric artery and the inferior pancreaticoduodenal artery.
Definition: The first region (i.e., most proximal region) of the small intestine. Chyme leaving the stomach (through the pyloric valve) first enters the duodenum.
1 paź 2022 · The duodenum extends from the stomach to the duodenojejunal flexure; the proximal two-fifths of the remaining small intestine is the jejunum and the distal three-fifths is the ileum.
1 sty 2019 · Thus the duodenum derives its sympathetic innervation from both celiac (proximal duodenum) and superior mesenteric (distal duodenum) ganglia. These fibers consist of both cholinergic and noradrenergic neurons; however, the sympathetic innervation of the stomach and duodenum is largely inhibitory.
24 maj 2024 · The duodenum pushes food molecules that don’t get absorbed into the next section of your small intestine, the jejunum. The duodenum squeezes and relaxes, creating a wave-like forward motion called peristalsis.
From the celiac trunk, the gastroduodenal artery is a branch of the hepatic artery and serves the proximal portion of the duodenum. It directly gives rise to branches that serve the duodenal cap. The superior pancreaticoduodenal artery is a terminal branch of the gastroduodenal artery.
