Coeliac Trunk (T12) Superior Mesenteric Artery (L1) Inferior Mesenteric Artery (L3)…3 paired lateral Visceral branches of Abdominal Aorta include:

1. Middle Suprarenal(L1)
2. Renal (between L1 and L2)
3. Gonadal (L2)

What is abdominal aorta and branches?

The abdominal aorta has: Three single anterior visceral branches (coeliac, superior mesenteric artery, inferior mesenteric artery) Three paired lateral visceral branches (suprarenal, renal, gonadal) Five paired lateral abdominal wall branches (inferior phrenic and four lumbar)

Where does the abdominal aorta terminate?

The abdominal aorta runs from the diaphragm and ends just above the pelvis, where it divides into the iliac arteries.

What are the parietal branches of the abdominal aorta?

Parietal Branches

• Inferior phrenic artery → phrenic and supra-renal branch.
• Renal artery → ureteric and supra-renal branch → apical, upper, middle, lower and posterior branches.
• Gonadal artery.
• Lumbar arteries.
• Spinal arteries.
• Common iliac artery.

How can I remember my abdominal arteries?

Mnemonic

1. I: iliolumbar artery.
2. L: lateral sacral artery.
3. G: gluteal (superior and inferior) arteries.
4. P: (internal) pudendal artery.
5. I: inferior vesical (vaginal in females) artery, and superior vesical artery.
6. M: middle rectal artery.
7. V: vaginal artery (females only)
8. O: obturator artery.

How can I remember my aorta?

​Mnemonic

1. A: arch of aorta.
2. B: brachiocephalic trunk.
3. C: left common carotid artery.
4. S: left subclavian artery.

What does your abdominal aorta do?

The abdominal aorta enters the abdomen through the diaphragm at the level of the twelfth thoracic vertebre and continues to just below the umbilical area, where it splits into the right and left common iliac arteries. The aorta supplies oxygenated blood to most of the body.

At which vertebral level does the abdominal aorta terminate?

The descending thoracic aorta passes through the diaphragm’s aortic hiatus at the T12 vertebral level at which point it continues as the abdominal aorta. The abdominal aorta terminates as it bifurcates into common iliac arteries, which subsequently provide arterial supply to the pelvis and lower limbs.

What is abdominal aorta?

It is a continuation of the thoracic aorta. It begins at the diaphragm, and runs down to the point where it ends (by splitting in two to form the common iliac arteries). The abdominal aorta supplies oxygenated blood to all of the abdominal and pelvic organs and the legs.

What are the 3 branches of aorta?

The convexity of the aortic arch gives off three branches; the brachiocephalic trunk, the left common carotid artery and the left subclavian artery.
