Superior mesenteric artery

The superior mesenteric artery and its branches.

The superior mesenteric artery ("upper visceral artery ") is an unpaired branch of the aorta and arises behind the neck of the pancreas between the trunk of the celiac trunk and the renal arteries ( renal artery ), i.e. approximately at the level of the first lumbar vertebra . In domestic animals, it arises directly behind the coeliaca artery and is known as the cranial mesenteric artery ("intestinal artery located towards the skull").

The superior mesenteric artery is connected to the inferior mesenteric artery via the Riolan's anastomosis .

human

Originating from the superior mesenteric artery of humans:

• Arteria pancreaticoduodenalis inferior (pancreatic and duodenal arteries )
  with left and right branches, these together with the ascending and descending branches of the arteriae colica dextra et sinistra form the arteria marginalis coli , whichruns alongthe large intestine and supplies it
• Arteria ileocolica (iliac and colon arteries )
  • Anterior and posterior caecal arteries (anterior and posterior appendix arteries )
  • Appendicular artery (appendix artery )
• Arteria colica dextra (right colon artery )
• Arteria colica media (middle large intestinal artery )
• various intestinal arteries supplying the ileum (ileum) and jejunum (empty intestine) ( arteriae ileales and arteriae jejunales ).

Pets

The cranial mesenteric artery of animals has the following branches:

• Arteria pancreaticoduodenalis caudalis (posterior pancreatic-duodenal artery )
• Arteriae jejunales (empty bowel arteries )
• Arteriae ilei (hip arteries )
• Arteria ileocolica (hip and colon artery )
• Caecal artery (appendix artery )
• Arteria colica dextra (right colon artery )
• Arteria colica media (middle colon artery )
