What are the 3 veins in the arm?
Veins of the arm and axilla include superficial veins (cephalic and basilic veins) and deep veins (brachial and axillary veins).
Where is cephalic vein located?
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.
Where is the dorsal metacarpal vein located?
Anatomical Parts The dorsal digital veins pass along the sides of the fingers and are joined to one another by oblique communicating branches. Those from the adjacent sides of the fingers unite to form three dorsal metacarpal veins which end in a dorsal venous net-work opposite the middle of the metacarpus.
Where is the biggest vein in your arm?
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 vein should be avoided?
While hand veins may be utilized for blood draws and intravenous infusions, veins in the feet and legs should be avoided for adults. Drawing from these sites can cause blood clotting and hemostasis.
Where are deep veins in arm?
The deep veins of the upper extremity include the paired ulnar, radial, and interosseous veins in the forearm; paired brachial veins of the upper arm; and axillary vein. The axillary vein originates at the lower border of the teres major muscle in continuity with the brachial veins.
Why is the cephalic vein in the arm?
The cephalic vein drains the lateral side of the superficial venous network of the dorsum, which in turn drains blood from the palm of the hand 2. As it ascends, the cephalic vein drains blood from the lateral aspect of the upper limbs via small superficial veins 1.
What are the 3 main veins in the antecubital fossa?
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).
Which veins are used for cannulation?
The preferred sites for IV cannulation
- Hand. Dorsal arch veins.
- Wrist. Volar aspect.
- Cubital fossa. Median antecubital, cephalic and basilic veins.
- Foot. Dorsal arch.
- Leg. Saphenous vein at the knee.
Where is the main artery in your left arm?
What is 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. It separates into several branches along its route.
Is there a vein in your arm that connects to your heart?
Blood travels from the heart into the subclavian artery which continues on down the arm as the axillary artery. The axillary artery travels deep in the arm pit and gives off several small branches which feed muscles and bones around the shoulder.
What needle size would not be appropriate to draw blood with?
Small-bore needles of 25 G or less cannot be universally recommended when collecting venous blood for clinical chemistry testing and should be reserved for selected circumstances, such as in patients with problematical venous accesses and newborns.
What vein do you draw blood from in the arm?
For adult patients, the most common and first choice is the median cubital vein in the antecubital fossa. Commonly referred to as the antecubital or the AC it can be found in the crevice of the elbow between the median cephalic and the median basilic vein.
Which vein is the deepest?
Deep veins are almost always beside an artery with the same name (e.g. the femoral vein is beside the femoral artery). Collectively, they carry the vast majority of the blood. Occlusion of a deep vein can be life-threatening and is most often caused by thrombosis….

Why is the basilic vein the last choice?
While you can usually see it clearly, it’s considered a last resort in medical procedures. That’s because it’s close to important structures of the body that can potentially be injured and it’s less stable than the other two major veins in the arms.
Is cephalic vein superficial or deep?
The basilic and cephalic veins, which are superficial veins, contribute to the axillary vein, though many anatomic variations occur. After passing the outer margin of the first rib, the axillary vein continues as the subclavian vein.
What is the function of the blood vessels in the arm?
Function and anatomy of arm blood vessels. Each arm contains several important veins and arteries. Veins carry blood toward the heart, while arteries transport blood from the heart to other areas of the body. Below are some of the main veins and arteries of the arm.

What are the venous commantantes of the forearm?
As with the veins in the calf, the veins of the forearm genarally run in pairs (venous commantantes). An upper limb DVT series should include the following minimum images
Which veins appear to be pulsatile in the upper arm?
Depending on arm movement and respiration, the Axillary and subclavian veins may appear pulsatile. Transverse mid upper arm. Transverse ultrasound view of the Brachial and Basilic veins.
