The axillary vein is a major vein in the upper body that carries blood from the upper limb, armpit, and the upper side of the chest wall towards the heart.
What does the axillary vein become?
The axillary vein then becomes the subclavian vein above the lateral border of the first rib. The axillary vein lies medial to the axillary artery. It is separated from artery by the medial pectoral nerve, medial cord of the brachial plexus, and the ulnar nerve.
What regions does the axillary vein drain?
The axillary vein drains deoxygenated blood from the arm, axilla and superolateral chest wall 4. It also receives contributions from the thoracoepigastric vein of the anterolateral abdominal wall 5.
What does the axillary vein innervate?
The axillary vein then reaches the lateral border of the 1st rib, where it terminates by becoming the subclavian vein. … The axillary vein receives tributaries that correspond to the branches of the axillary artery. Namely, these veins are the subscapular, circumflex humeral, lateral thoracic and thoracoacromial veins.What does the axillary supply?
The axillary nerve supplies three muscles in the arm: deltoid (a muscle of the shoulder), triceps (long head) and teres minor (one of the rotator cuff muscles). The axillary nerve also carries sensory information from the shoulder joint.
What is axillary vein thrombosis?
Definition. Acute swelling and pain in the upper limb due to occlusion of the axillary and/or subclavian veins by thrombus. This may occur as a primary phenomenon or as a result of secondary factors such as the placement of an indwelling venous catheter, thrombophilia or thoracic outlet syndrome.
Is axillary vein deep or superficial?
Deep veins — 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 becomes the subclavian vein at the lower border of the teres major muscle (figure 2).
How do you know if you have an axillary vein?
The axillary vein can be visualized simply as a bluish cord while dissecting yellowish fat globules around it after opening the fibrous fascia. The axillary vein is then dissected downwards and laterally along its course towards the arm.Where does the axillary nerve end?
At the inferior end of the subscapularis the axillary nerve then runs posterior, close to the joint capsule, passing through the quadrangular space with the posterior circumflex humeral artery, sandwiched between the lateral and long heads of the triceps muscle.

Article first time published onWhat is the longest vein in the body?
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.
What does lateral thoracic artery supply?
The lateral thoracic artery supplies the axillary lymph nodes, serratus anterior, pectoralis major, pectoralis minor and subscapularis muscles. … Additionally, it can provide blood supply to the breast in females.
Where does the blood flow from the axillary artery?
Anatomical terminology In human anatomy, the axillary artery is a large blood vessel that conveys oxygenated blood to the lateral aspect of the thorax, the axilla (armpit) and the upper limb. Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery.
What is the axillary artery a continuation of?
The axillary artery represents the continuation of the subclavian artery and is a major artery of the upper limb.
What happens when the axillary nerve is damaged?
Axillary nerve dysfunction is nerve damage that can lead to a loss of movement or sensation in the shoulder. Conditions associated with axillary nerve dysfunction include fracture of the humerus (upper arm bone), pressure from casts or splints, and improper use of crutches.
Is axillary vein deep?
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.
What causes veins to be more visible in arms?
Your arms may appear veiny both when exercising and standing still. Protruding veins in your muscles can be the result of a low body fat percentage and high muscle mass.
How deep are veins under the skin?
The range of 0.2-2.0mm is set based on the shallowest penetration to the deepest penetration of light into the skin layer at a certain wavelength (i.e. 420nm, 585nm, and 800nm) and also the most superficial position of the vein is located.
What are the symptoms of a blood clot in the arm?
- swelling, usually in one arm.
- cramping-type pain.
- tenderness to the touch.
- reddish or bluish tone to the skin.
- warm to the touch.
How do I know if I have a blood clot in my right arm?
Symptoms of a blood clot in the arm skin that is warm to the touch. pain that feels like cramping. swelling in the arm where the clot is. a red or blue hue to the skin.
What artery is under your armpit?
Axillary Artery: This is a continuation of the subclavian artery. This artery travels deep in the arm pit, feeding muscles and bones around the shoulder with its branches. It eventually turns into the brachial artery.
What muscles does axillary nerve supply?
The axillary nerve has both a motor and a sensory distribution of innervation. It has motor fibres that innervate the deltoid muscle, acting as an abductor, flexor and extensor at the shoulder joint, as well as the teres minor muscle, allowing lateral rotation of the glenohumeral joint.
What nerves are in your armpit?
Nerves: A nerve-relay station called the brachial plexus lies just above the armpit. Major nerves that pass through it are the median, ulnar, radial, and musculocutaneous nerve. Sweat glands: The many sweat glands in the armpit are responsible for underarm odor.
What is axillary nerve palsy?
Axillary nerve palsy is a neurological condition in which the axillary (also called circumflex) nerve has been damaged by shoulder dislocation. It can cause weak deltoid and sensory loss below the shoulder. Since this is a problem with just one nerve, it is a type of Peripheral neuropathy called mononeuropathy.
What does the subclavian vein drain into?
The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).
What are all of the blood vessels that directly flow into the axillary vein?
The blood in the axillary vein drains into the subclavian vein. The subclavian veins will merge with the internal jugular veins from the head to form the brachiocephalic veins. The brachiocephalic vein from each upper extremity will merge to form the superior vena cava.
Is the axillary vein in the axillary sheath?
The structures traversing the apex of the axilla are grouped into a neurovascular bundle. However, the axillary vein (as well as lymphatics and lymph nodes) is outside the axillary sheath, providing room for it to expand. …
How many axillary veins are there?
In human anatomy, the axillary vein is a large blood vessel that conveys blood from the lateral aspect of the thorax, axilla (armpit) and upper limb toward the heart. There is one axillary vein on each side of the body.
What is the strongest vein in the body?
The two largest veins in the body are the superior vena cava, which carries blood from the upper body directly to the right atrium of the heart, and the inferior vena cava, which carries blood from the lower body directly to the right atrium.
What does saphenous mean?
Definition of saphenous : of, relating to, associated with, or being either of the two chief superficial veins of the leg saphenous nerve.
What vein drains blood from the face and scalp?
External jugular vein: The more superficial of the two jugular veins situated on each side of the neck. The other is the internal jugular vein. They drain blood from the head, brain, face and neck and convey it toward the heart.
