Where are the superior and inferior mesenteric arteries?
The superior mesenteric artery supplies the midgut from the ampullary region of the second part of the duodenum to the splenic flexure of the large intestine. The inferior pancreaticoduodenal artery arises from the SMA and, along with the superior pancreaticoduodenal artery, supplies the head of the pancreas.
What is a superior mesenteric artery?
In human anatomy, the superior mesenteric artery (SMA) 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, as well as the pancreas.
What are the major branches of the abdominal aorta from superior to inferior?
There are five arteries that branch from the abdominal aorta: the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the renal arteries and the iliac arteries.
What does the inferior mesenteric do?
The inferior mesenteric artery arises from the abdominal aorta at the level of the third lumbar vertebra. It supplies the hindgut and has four major branches called left colic, sigmoid and superior rectal arteries. It also contributes to the formation of the marginal artery of Drummond.
Is superior mesenteric artery life threatening?
Superior mesenteric artery syndrome: A rare but life threatening disease.
What are the symptoms of superior mesenteric artery syndrome?
Symptoms may include abdominal pain, fullness, nausea, vomiting, and/or weight loss. SMAS typically is due to loss of the mesenteric fat pad (fatty tissue that surrounds the superior mesenteric artery). The most common cause is significant weight loss caused by medical disorders, psychological disorders, or surgery.
What are the major branches of the abdominal aorta from inferior to superior?

How serious is superior mesenteric artery syndrome?
Superior mesenteric artery (SMA) syndrome is a rare type of compression of the small intestine. It’s a treatable condition, but a delayed diagnosis can lead to more severe symptoms or even death.
What does the inferior mesenteric artery do?
Inferior mesenteric artery and its branches in humans. The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract. Both the superior and inferior mesenteric arteries arise from the abdominal aorta.
What is the superior mesenteric artery (SMA)?
The superior mesenteric artery (SMA) is a major artery of the abdomen. It arises from the abdominal aorta, and supplies arterial blood to the organs of the midgut – which spans from the major duodenal papilla (of the duodenum) to the proximal 2/3 of the transverse colon.
What veins are between the superior mesenteric artery and the aorta?
Located under this portion of the superior mesenteric artery, between it and the aorta, are the following: left renal vein – travels between the left kidney and the inferior vena cava (can be compressed between the SMA and the abdominal aorta at this location, leading to nutcracker syndrome).
What does the inferior pancreaticoduodenal artery supply?
Inferior pancreaticoduodenal artery- This is the first branch of the superior mesenteric artery, arising from its right side, and supplies the head of the pancreas as well as the inferior and ascending regions of the duodenum. This artery gives off two further branches i.e. anterior and posterior branches.
