- Coeliac trunk (T12) - foregut
- Superior mesenteric (L1) - midgut
- Middle suprarenal - adrenal glands
- renal - kidneys

Q

Coeliac trunk branches

A

Left gastric = lesser curve and oesophagus - Anteriorly meeting right gastric

Splenic = spleen, pancreas and greater curvature - coiled nature, moves left and posterior

Common Hepatic = liver - Only branch to move right, dividing into right gastric ( then proper hepatic) and gastroduodenal

Q

Superior mesenteric artery

A
  • Branches from the abdominal aorta at the L1 level
  • Supplies the midgut

Branches: inferiorpancreaticoduodenal, jejunal and ileal, middle and right colic, ileocolic

  • Occlusion causes intestinal ischaemia
17
Q

Inferior mesenteric artery

A

*Branches from there aorta at the L3 level

  • Supplies hind gut

Branches: Left colic, sigmoid and superior rectal
