The olecranon, the medial epicondyle, the lateral epicondyle, the radial head, the location of the posterior interosseous nerve, and the biceps tendon in the antecubital fossa.

This is now going to dump into what we call a venule.

There is actually a little spot right there that they drain in to.

I'll write that right here.

Into the IV, yes.

And let me actually show you where the blood vessels come from. These are called coronary vessels I just write the word coronary here.

So you have these arteries right over here, the red tubes. Those are arteries. and then the blue ones are veins.

There's also another one over here called the superior vena cava, and this is bringing back blood from the arms and head.

And at the bottom here, you can't see it because it's on the other side of the heart, but there's another vein called the inferior vena cava.

Start a largebore IV. Keep it open.

Inferior vena cava, and this is the large vein that brings back all the blood from the bottom half of the body.

It's almost like another generator came online, jacked into the system and overloaded it with double or triple the voltage.

And it generally travels through two major kind of vessels.

I'm going to do some surgery here.

Check resisted opposition strength of the thumb to check the median nerve and resisted digit abduction for the ulnar nerve.

If the patient has reproduction of pain or numbness, consider thoracic outlet syndrome.

(English captions by Andrea Matsumoto from the University of Michigan)

I could just write artery and vein and essentially they would be behaving this way.

that looks like a red ligament with blue veins on the right side

A venule, and this venule is gonna basically then feed into many, many other venules.

Resisted digit abduction tests the ulnar nerve.

And you might say, well that wasn't so difficult. I'll say bronchial vessels, because there are also some veins coming off.

Have the patient take a deep breath and extend neck, and rotate head towards the painful shoulder.

Well, these vessels, all of them, together are called coronary vessels.

They would ordinarily support fish and other wildlife.

And fortunately he didn't die.

It's keeping me standing. It's involved in coordinated movement.

And so they don't dump necessarily directly into the inferior superior vena cava.

In concluding the wrist exam it is important to document a neurovascular exam.

So you think of alternative mechanical parts.

She was being given medicine intravenously.

So Superior Vena Cava and Inferior Vena Cava.

Maybe from the second toe, and it's gonna basically all kind of gather together, and again, to a giant, giant set of veins.

I need two largebore Ivs, 6 units Oneg, type and cross for 6 more units,

So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart, and, generally speaking, these are all considered, of course, veins.

We're only going to talk about three of them.

A little vein in his head popped, and that was that.

I hope my veins don't pop.

So, here you have a giant vein, this is a vein, and you have an artery.

On the right is the Sea of Tranquility.

You know, maybe veins are dumping in here now, maybe another vein dumping in here, and these veins are all going to dump into an enormous vein that we call the inferior vena cava.

Check for wrist flexion extension radial deviation ulnar deviation thumb extension

The reason is, they're treating other people like a computer, and the brain is too.

And it's actually coming into two veins, the one at the top, this is called the superior, superior just kind of means at the top.

And then you've got the capillaries, you've got some blood kind of from both places the pulmonary circulation and the blood from the systemic circulation again mixing.
