Untitled Deck Flashcards
What are the three unpaired visceral branches of the abdominal aorta, and their vertebral levels?
Celiac trunk (CA): T12
Superior mesenteric artery (SMA): L1
Inferior mesenteric artery (IMA): L3
What are the three paired visceral branches of the abdominal aorta?
Median suprarenal arteries
Renal arteries: L2
Testicular or ovarian arteries
What are the parietal branches of the abdominal aorta?
Inferior phrenic arteries
Four lumbar arteries
Median sacral artery
Two terminal
branches (L4):
1. Right common iliac
artery
2. Left common iliac
artery
What are the two terminal branches of the abdominal aorta, and their level?
The right and left common iliac arteries at L4.
Where does an abdominal aortic aneurysm typically occur?
Just above the bifurcation of the aorta (at the level of L4), crossed by the third part of the duodenum.
Where can the pulsations of a large abdominal aortic aneurysm be detected?
To the left of the midline in the umbilical region.
Into what branches do the common iliac arteries bifurcate?
The internal iliac artery and the external iliac artery.
What are the two branches of the external iliac artery, and where does it continue?
Inferior epigastric artery
Deep circumflex iliac artery
After these branches, it continues as the femoral artery behind and below the inguinal ligament.
What does the internal iliac artery supply?
Pelvic organs.
How does the inferior vena cava begin?
By the union of the two common iliac veins anterior to the L5 vertebra, posterior to the right common iliac artery.
Does the inferior vena cava receive blood directly from the GI tract?
No.
What are the tributaries of the IVC?
Happy Rabbits Sing In Large Cages
Visceral:
2–3 Hepatic veins
2 Renal veins
Right suprarenal vein
Right testicular or ovarian vein
Parietal:
2 Inferior phrenic veins
3–4 Lumbar veins
Roots:
2 Common iliac veins
