What artery supplies blood to the anterior portion of the lower leg?

hypocaffeinemia, BSN, RN · Feb 14, 2009

The external iliac artery branches off of the aorta and quickly becomes the femoral artery. The femoral artery terminates as the popliteal artery, and the anterior tibial artery branches from the popliteal.

It's all the same source, but the anterior tibial artery, aptly named, is what directly supplies the anterior tibial region.

thank you.

the common iliac artery is formed from the bifurcation of the abdominal aorta, right?

its not the external iliac artery is formed from the bifurcation of the abdominal aorta.. thats wrong

Here's the deal: There's one main "pipeline" that changes names throughout its course depending on anatomic region, with many smaller pipelines branching off along the way.

The aorta does bifurcate into the common iliacs, yes, but the external iliac is the "main pipeline" extention of the the common iliac, with the internal iliac being a much smaller artery that has branched off. It is not an equal bifurcation. You can follow this main pipeline into the femoral, popliteal, and anterior tibial arteries.

I say this because your post makes it out to sound like there is a qualitative difference between the common iliac and the external iliac, when they are actually essentially the same. "External" is just an anatomic clarification term after the internal iliac has branched off.

the question is:

____ Formed from the bifurcation of the abdominal aorta

and the directions say "there is only one correct response for each description"

The answer to such a question would be "common iliac arteries".

I'm just explaining things to help understand the anatomy.

For example, it's weird that we refer to the aorta as "the aorta" its entire length. To understand what I mean regarding lower limb blood supply, imagine that after every single branch off the aorta we gave it a different name.

i know, i appreciate it. we havent really started the blood vessels yet and theres already homework for it so its a little confusing.

can someone tell me if these are right?

1. receives blood from the venous sinuses of the brain? internal jugular vein

2. Deep vein of the arm? brachial vein

3. Drains blood from the liver into the inferior vena cava? hepatic vein

4. Vessel between the superior mesenteric vein and liver? Great saphenous vein

1. Correct.

2. Correct. The radial and ulnar veins, which meet to form the brachial vein, are also considered deep veins.

3. Correct, but plural: hepatic veins

4. Incorrect. The great saphenous veins are located in your legs. The correct answer is the hepatic portal vein.

2. Correct. The radial and ulnar veins, which meet to form the brachial vein, are also considered deep veins.

radial or ulnar could also be the answer. but i think its brachial because it has to do with the arm while the radial/ulnar have to do with the forearm. hope its right.

thank you so much for helping me:up:
