The brachial vein is a component of the deep venous system of the upper limb. After forming from the radial and ulnar veins1, the brachial vein travels from the cubital fossa superiorly to become the axillary vein.
What does the brachial vein supply blood to?
The brachial artery supplies blood to much of the brachial region and divides at the elbow into several smaller branches, including the deep brachial arteries, which provide blood to the posterior surface of the arm, and the ulnar collateral arteries, which supply blood to the region of the elbow.
Is the brachial vein a superficial or deep vein?
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 basilic and cephalic veins, which are superficial veins, contribute to the axillary vein, though many anatomic variations occur.
What does the brachial vein become?
The brachial vein (deep vein) accompanies the brachial artery in the region of the arm. It is formed by the unification of the ulnar and radial veins at the elbow. The basilic vein joins the brachial vein and becomes the axillary vein at the inferior border of the teres major muscle.
How deep is the brachial vein?
In human anatomy, the brachial veins are venae comitantes of the brachial artery in the arm proper. Because they are deep to muscle, they are considered deep veins. …

Where is the brachial plexus nerve located?
The brachial plexus is a network of nerves in the shoulder that carries movement and sensory signals from the spinal cord to the arms and hands. Brachial plexus injuries typically stem from trauma to the neck, and can cause pain, weakness and numbness in the arm and hand.
Are there two brachial veins?
The brachial veins are usually 2 in number and they are located on either side of the brachial artery. They are usually formed by the union of the radial and the ulnar venae comitantes, near the level of the elbow [1].
What artery in the body has the largest diameter?
The aorta is the first arterial segment of the systemic blood circulation, directly connected to the heart. The aorta is the largest artery in the human body, with a diameter of 3 cm at its origin (ascending aorta), 2.5 cm in the descending portion (thoracic aorta), and 1.82 cm in the abdomen (abdominal aorta).
Under which vein is the brachial artery located?
The brachial artery continues from the axillary artery at the shoulder and travels down the underside of the arm. Along with the medial cubital vein and bicep tendon, it forms the cubital fossa, the triangular pit on the inside of the elbow.
What does a thrombosed vein look like?
The skin over the vein becomes red, and the area feels warm and is very tender. Because blood in the vein is clotted, the vein feels like a hard cord under the skin, not soft like a normal or varicose vein. The vein may feel hard along its entire length.
Which vein is best for drawing blood?
The median cubital vein is the first choice for blood draws because it has a decreased proximity to arteries and nerves in the arm. The more lateral cephalic vein is the second choice and the basilic vein in the medial arm is the last choice.
What does a DVT in the arm feel like?
When they occur, the symptoms of a blood clot in the arm may include: skin that is warm to the touch. pain that feels like cramping. swelling in the arm where the clot is.
What is the longest vein in the body?
Great Saphenous Vein Great Saphenous Vein (GSV) – The GSV is the large superficial vein of the leg and the longest vein in the entire body. It can be found along the length of the lower limb, returning blood from the thigh, calf, and foot to the deep femoral vein at the femoral triangle. The femoral triangle is located in the upper thigh.
Which vein of the upper limb is the most common site for drawing blood?
median cubital vein In human anatomy, the median cubital vein (or median basilic vein) is a superficial vein of the upper limb. It is very clinically relevant as it is routinely used for venipuncture (taking blood) and as a site for an intravenous cannula.
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).
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.

| Drainage area | Radial parts of the hand, forearm and arm |
Why basilic vein is the last choice for venipuncture?
The basilic vein is responsible for taking blood that doesn’t have oxygen from the arms back to the heart and lungs, where it’s given oxygen again. While you can usually see it clearly, it’s considered a last resort in medical procedures.
How do you treat brachial plexus neuropathy?
Treatment of patients with acute brachial plexus neuritis includes analgesics, often narcotics (e.g., hydrocodone), which may be required for several weeks, physical therapy for three to eight weeks to help maintain strength and mobility, and encouragement that the condition will slowly improve in the vast majority of …
Can brachial plexus injury heal on its own?
Many injuries to the brachial plexus will recover spontaneously without surgery over a period of weeks to months, especially if they are mild. Nerve injuries that heal on their own tend to have better functional outcomes.
What doctor treats brachial plexus?
People with brachial plexus injuries usually see three surgeons during one office visit at Mayo Clinic. At Mayo Clinic, neurosurgeons, orthopedic surgeons, hand and microvascular surgeons, physical rehabilitation experts, and other specialists collaborate as a team to evaluate and treat each patient.
Does the brachial vein pass through the arm?
It travels down the upper arm and through the elbow before dividing into the radial and ulnar arteries below the elbow. In the shoulder, branches of the brachial artery provide oxygenated blood to the muscles and bones.
How do you know if you hit an artery instead of a vein?
You’ll know you hit an artery if: The plunger of your syringe is forced back by the pressure of the blood. When you register, the blood in your syringe is bright red and ‘gushing. ‘ Blood in veins is dark red, slow-moving, and “lazy.”
Where is your main vein located?
Systemic veins are located throughout the body from the legs up to the neck, including the arms and trunk. They transport deoxygenated blood back to the heart.
Where is the largest artery in your body?
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body.
What is the largest artery and vein in the body?
The aorta is the large artery leaving the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
Do veins carry more blood than arteries?
Because the walls of the veins are thinner and less rigid than arteries, veins can hold more blood. Almost 70 percent of the total blood volume is in the veins at any given time.
Why can’t I feel my brachial pulse?
If you can’t feel the pulse, try pressing a little harder into your arm. The brachial artery is deep in the muscle, so it can take some gentle pressure to feel. … If you or whomever you’re checking the pulse of feels any discomfort from the pressure of your fingers, you’re pushing too hard.
What happens if you cut the brachial artery?
The Brachial artery runs along the inside of your arms. This artery is deep, but severing it will result in unconsciousness in as little as 15 seconds, and death in as little as 90 seconds.
Where do you feel the brachial pulse?
The brachial pulse can be located by feeling the bicep tendon in the area of the antecubital fossa. Move the pads of your three fingers medial (about 2 cm) from the tendon and about 2–3 cm above the antecubital fossa to locate the pulse.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
