Anatomy Superior Mesenteric Artery

Anatomy Of Superior Mesenteric Artery Medicinebtg The superior mesenteric artery is in the midsection of the digestive tract (midgut). it originates from the aorta between the celiac artery and renal arteries. the celiac artery supplies blood to the liver, spleen and stomach. the renal arteries send blood to the kidneys. the superior mesenteric artery travels behind the pancreas. The superior mesenteric artery gives rise to numerous arteries that supply the jejunum and ileum. the arteries pass between the layers of the mesentery and form anastomotic arcades – from which smaller, straight arteries (known as the “vasa recta”) arise to supply the organs (fig 2). the jejunal blood supply is characterised by a smaller.

Branches Of The Superior Mesenteric Artery Figure Modified From 20th Superior mesenteric artery syndrome this is a rare disease that occurs when the duodenum is trapped between the abdominal aorta and the superior mesenteric artery, causing compression or complete obstruction. the patient will present with bloating after meals, nausea and vomiting and a feeling of abdominal fullness. 14749. anatomical terminology. [edit on wikidata] in human anatomy, the superior mesenteric artery (sma) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two thirds of the transverse colon. The superior mesenteric artery is the second major branch of the abdominal aorta. it originates on the anterior surface of the aorta at the level of the l1 vertebrae, approximately 1 cm inferior to the celiac trunk and superior to the renal arteries. anterior to the superior mesenteric artery lies the pylorus of the stomach, the neck of the pancreas, and the splenic vein. posterior to the. Supply. the superior mesenteric artery is the artery to the midgut. it supplies the gut from the ampulla of vater of the 2 nd part of the duodenum to the distal third of the transverse colon, and includes structures in between such as 5: the inferior pancreaticoduodenal artery also supplies the head of the pancreas.
