Where are the cephalic basilic and median cubital veins located?
The basilic vein originates on the medial aspect of the forearm at the wrist from the dorsal venous network of the hand. It runs superficially in the forearm and usually communicates with the cephalic vein via the median cubital vein at the elbow.
What are the 3 main veins in the arm?
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).
Where is basilic vein present?
The basilic vein usually lies in the deep subcutaneous tissue at the antecubital crease and pierces the brachial fascia in the distal third of the upper arm; however, occasionally it lies beneath the fascia at the antecubital crease.
Where is the median cubital vein located?
cubital fossa
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.
Where is the median cephalic vein?
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. The superficial venous network is the source of blood for most blood tests, and is the easiest place to access venous blood.
What are the 3 types of veins?
There are four types of veins:
- Deep veins are located within muscle tissue.
- Superficial veins are closer to the skin’s surface.
- Pulmonary veins transport blood that’s been filled with oxygen by the lungs to the heart.

Where is median cubital vein located?
Where is your cephalic?
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.
Where is the cephalic vein located quizlet?
Vein located at the side of the neck that carries blood returning to the heart from the head, face, and neck.
What is the function of 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.
What is the smallest vein in the body?
Capillaries are the smallest blood vessels in the body. How small are they? About ten of them equal the thickness of one human hair, and most are so small that only one blood cell can pass through them at a time.
What is the biggest vein in the body?
inferior vena cava
Your inferior vena cava, your body’s largest vein, carries oxygen-depleted blood back to your heart from the lower part of your body (below your diaphragm).
What are 3 common sites for venipuncture?
In this elbow pit, phlebotomists have easy access to the top three vein sites used in phlebotomy: Median cubital vein. Cephalic vein. Basilic vein.
What are the 3 most common veins used in phlebotomy where are they located?
They are the cephalic, median cubital, and basilic veins. These three veins are found in the antecubital area. The cephalic vein is found on the lateral, or outside, of the arm.
What is the cephalic vein?
The cephalic vein is a superficial vein which courses along the anterolateral aspect of the arm and continues into the deltopectoral groove to empty into the subclavian vein.
Where is the median cubital vein found?
elbow joint
Why is cephalic vein called?
Which is the largest vein?
vena cava
The largest vein in the human body is the vena cava which consists of superior and inferior vena cava.
What is the smallest vein?
Capillaries
Capillaries, the smallest blood vessels, connect arteries and veins.
What are the 4 types of veins?
Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins. Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.
What are the four common venipuncture sites?
After the needle selection, phlebotomists begin to look and feel for a viable vein. The first attempt is the antecubital fossa area, starting with the median cubital vein, then the cephalic vein, and the basilic vein. If none of these veins work, then the phlebotomists use the hand veins.
Why is median cubital vein the best site for IV?
The median cubital vein is routinely used for venipuncture (taking blood) and as a site for an intravenous cannula. This is due to its particularly wide lumen, and its tendency to remain stationary upon needle insertion. It becomes prominent when pressure is applied upstream, which makes needle insertion easier.
What is the longest vein in the arm?
| Basilic vein | |
|---|---|
| The most frequent variations of the veins of the forearm (schematic). | |
| Details | |
| Source | Dorsal venous network of hand |

Which is the smallest vein?
Capillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
