Vasculature of distal UE

Question 1

What are the major arteries of the distal UE?

Answer 1

Brachial artery: splits into radial artery and ulnar artery at elbow

Question 2

As the deep artery travels around the humerus and descends by the elbow, it’s renamed what?

Answer 2

Radial collateral artery

Question 3

As the brachial artery descends, which collateral arteries does it give off?

Answer 3

Superior and Inferior ulnar collateral

Question 4

As the ulnar artery descends, it sends out a collateral artery to loop back to the elbow, what is this artery called?

Answer 4

Ulna recurrent artery

Question 5

As the radial artery descends, it sends out a collateral artery to loop back to the elbow, what is this artery called?

Answer 5

Radial recurrent artery

Question 6

As the radial artery descends to the hand/wrist, it makes an anastomosis with which artery?

Answer 6

Ulnar

Question 7

Which artery do you feel as a “pulse” in the wrist?

Answer 7

Radial artery

Question 8

The radial artery travels posterior to the thumb to form what?

Answer 8

Deep palmer arch (how the radial artery connects to the ulnar artery for anastomosis)

Question 9

The common interosseous artery branches off of what artery? How many branches does it then give off?

Answer 9

Ulnar, then immediately spits off into two branches

Question 10

What are the two branches of the common interosseous artery?

Answer 10

Anterior and posterior interosseous artery

Question 11

The ulnar artery then continues to the hand/wrist to form an anastomosis with which artery?

Answer 11

Radial artery

Question 12

What is the superficial palmer arch?

Answer 12

The loop of the ulnar artery on the back of the hand that forms an anastomosis to connects with the radial artery

Question 13

What is the deep palmer arch?

Answer 13

The loop of the radial artery on the front of the hand (floor of the palm) that passes posterior to the thumb to loop around and form an anastomosis to connect with the ulnar artery

Question 14

What is the deep veinous pathway of the upper extremity?

Answer 14

Deep veins of the arm that follow the same pathways of the arteries that brought the blood to the extremities

Question 15

What are the deep veins of the deep veinous pathway?

Answer 15

Radial vein, ulnar vein, brachial vein, axillary vein, subclavian vein

Question 16

How does the basilic vein contribute to the superficial venous pathway of the distal UE?

Answer 16

It drains blood from the forearm and continues up to proximal UE to return to deep venous return (continuation of last module)
*thumb side

Question 17

How does the cephalic vein contribute to the superficial venous pathway of the distal UE?

Answer 17

It drains blood from the forearm and continues up to the proximal UE to return to deep venous retuen (continuation of last module)
*pinky side

Question 18

How does the median antebrachial vein contribute to the superficial venous pathway of the distal UE?

Answer 18

Runs up the medial forearm and eventually joins with the basilic vein

Question 19

How does the median cubital vein contribute to the superficial venous pathway of the distal UE?

Answer 19

Connects the cephalic and the basilic veins in the region of the cubital fossa
