When does the aorta become the abdominal aorta?
By passing behind the median arcuate ligament and between the crura of the thoracic diaphragm
Note: T12
What does the abdominal aorta divide into?
Two common iliac
What are the anterior branches of AA?
Celiac trunk, CT
Superior mesenteric artery,SMA
Inferior mesenteric artery, IMA
What are the lateral branches of AA?
Inferior phrenic
Arteries to 3 paired glands:
Suprarrenal
Renal
Gonadal
What are the posterolteral branches of AA?
4 lumbar arteries
What are the posterior branches of AA?
Median sacral artery
What are the terminal branches of AA?
R/L common iliac
What lateral branch of AA may sometimes rise from CT?
Inferior phrenic artery
What artery does the inferior phrenic give off before supplying the crus of the thoracic diaphragm?
Superior renal artery
Behind what structure doe the inferior phrenic artery ascend?
Posterior to IVC (RT.) and esophagus (LT.)
Where is the celiac trunk found?
T12
What are the main branches of the celiac trunk?
- Left gastric
- Splenic
- Common hepatic
What are the branches of the left gastric? (From CT)

Gastric branches
May give off accessory elf hepatic artery or variant hepatic artery
What are the branches of the splenic artery? (From CT)
