What is the blood supply to the upper limb?

What is the blood supply to the upper limb?

The arterial supply of the upper limb is derived from the subclavian artery. The right subclavian artery originates from the brachiocephalic artery, which is the first branch of the aortic arch. The left subclavian artery originates directly from the aortic arch, being the third branch.

What are the 3 superficial veins of the upper limb?

Main superficial veins of the upper limb include the dorsal venous network, and the cephalic and basilic veins. Main deep veins of the upper limb include the superficial and deep venous palmar arches, the radial and ulnar veins, anterior and posterior interosseous veins, the brachial veins and the axillary vein.

Which vein of the upper limb is the most common site for drawing blood?

median cubital vein
The median cubital vein is a common site of venepuncture. It is a superficial vein that is located anteriorly to the cubital fossa region.

What artery supplies blood to the upper arm?

The brachial artery
The brachial artery is the major blood vessel supplying blood to your upper arm, elbow, forearm and hand. It starts in your upper arm, just below your shoulder, and runs down through the crease in front of your elbow.

What are the 11 major arteries that supply blood to the upper limbs?

Thus the major named arteries of the upper limb are: the subclavian artery, the axillary artery, the brachial artery, and the ulnar and radial arteries….Upper limb arteries

• Superior thoracic artery.
• Thoracoacromial, lateral thoracic arteries.
• Subscapular, anterior circumflex humeral, posterior circumflex humeral arteries.

Where is the cephalic vein?

The cephalic vein is located on the anterior antebrachium. It crosses from the medial aspect of the leg an inch or so proximal to the carpus to join the brachial vein proximal to the elbow, which ultimately joins the external jugular vein.

How many veins are in the upper limb?

In terms of arterial supply, the upper limb has 5 main vessels, the: subclavian, axillary, brachial, radial, and ulnar arteries.

What is the bicep vein called?

Cephalic vein
Cephalic vein: This large vein travels through the upper arm before branching near the elbow and into the forearm. It is often easily seen through the skin in the biceps region.

What are the 3 major veins used in venipuncture?

The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).

What is the AC vein?

The median cubital vein (antecubital vein) is a prominent superficial upper limb vessel. Its location is in the cubital fossa, on the anterior/flexor aspect of the elbow joint. This region of the upper limb is sometimes referred to as the antecubital area.
