Study Notes

The brachial artery enters the cubital fossa and bifurcates into radial and ulnar arteries.
The radial artery passes along the lateral aspect of the forearm, through the wrist, anatomical snuffbox, and between metacarpals I and II, ending as the deep palmar arch of the hand.
The subscapular artery, a branch of the axillary artery, is the largest and supplies the posterior axillary wall. It divides into circumflex scapular and thoracodorsal arteries.
The anterior circumflex humeral artery passes anterior to the surgical neck of the humerus and anastomoses with the posterior circumflex humeral artery.
The axillary artery has three parts, with the second part giving rise to branches like the thoraco-acromial artery and lateral thoracic artery.
The ulnar artery gives off the common interosseous artery, anterior interosseous artery, and terminates as the deep palmar artery.
Veins carry blood back to the heart, with deep veins typically following the arteries. Superficial veins are located in the superficial fascia.
The hand contains deep and superficial interconnected networks of veins, with the cephalic vein running laterally and basilic vein medially.
The cephalic vein joins the axillary vein through the clavipectoral fascia, while the subclavian vein becomes the axillary vein as it crosses rib I.
The brachiocephalic vein is formed by the union of the subclavian vein from the upper limb and internal jugular vein from the head and neck, draining into the superior vena cava and then to the right atrium of the heart.
