Why is median cubital vein used for drawing blood?
Of these three veins, the preferred one for venipuncture is the median cubital vein because it is larger and has a lower tendency to move or roll when the needle is inserted. There are also fewer nerve endings surrounding this vein making venipuncture less painful at this site.
What does the median cubital vein supply?
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. The median cubital vein connects the cephalic and basilic veins, which are the two major superficial veins of the upper limb.
What is a median cephalic vein?
In human anatomy, the cephalic vein is a superficial vein in the arm. It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps.
What is the function of the basilic vein?
The basilic vein drains the medial side of the superficial venous network of the dorsum of the hand, which in turn drains blood from the palm of the hand 2. As it ascends in the forearm and arm, the basilic vein drains the medial aspect of the upper limb via numerous superficial veins 1.
Why is the cephalic vein in the arm?
The cephalic vein is a superficial vein of the upper limb and it’s one of the two main veins of the arm. Its name derives from ‘cephalic’ meaning head, as the vein runs up to the shoulder….Cephalic vein.

What is the function of subclavian vein?
The primary function of the subclavian vein is to drain deoxygenated blood from the upper region of the body—including the arms and the shoulder areas—and transport it back to the heart. 6 Another important function of the subclavian is to collect lymph fluid from the lymphatic system from the internal jugular vein.
How is median cubital vein formed?
The median cubital vein is the superficial vein overlying the bicipital aponeurosis in the roof of the cubital fossa, commonly cannulated for intravenous access. It variably forms as either a H or M type pattern joining the median antebrachial, basilic and cephalic veins.
Where is the median cubital vein in the arm?
Median cubital vein (Vena mediana cubiti) 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. The median cubital vein connects
What is the function of the median basilic vein?
Median basilic vein. The cephalic vein is another vein located in the upper limb and is also referred to as the antecubital vein. It communicates through the elbow with the median basilic vein to the basilic vein. The basilic vein is large in size. This helps with the draining of some parts of the forearm and hand.
Which is the largest vein in the antecubital fossa?
In this, the most common pattern, the largest of the veins in the antecubital fossa is the median basilic vein. This is so because a deep vein connects with the median basilic vein in this area. Indeed, the median basilic vein is usually the first choice of phlebotomists.
When to apply a tourniquet to the median cubital vein?
Application of the tourniquet 3–4 in. above the site of collection applies pressure to the vein, impeding its flow of blood back to the heart and increasing the peripheral vein’s definition making them easier to locate and pierce during blood collection. Improper application of a tourniquet, however, can introduce numerous preanalytical errors.
