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.Their course is that of the brachial artery (in reverse): they begin where radial veins and ulnar veins join (corresponding to the bifurcation of the brachial artery).
The axillary artery is accompanied by the axillary vein, [2] which lies medial to the artery, along its length. In the axilla, the axillary artery is surrounded by the brachial plexus. [2] The second part of the axillary artery is the reference for the locational descriptions of the cords in the brachial plexus.

The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
The nerve lies at first behind the axillary artery, [4] and in front of the subscapularis, [1] and passes downward to the lower border of that muscle.. It then winds from anterior to posterior around the neck of the humerus, in company with the posterior humeral circumflex artery, [2] through the quadrangular space (bounded above by the teres minor, below by the teres major, medially by the ...
The two main veins are the basilic and the cephalic veins. There is a connecting vein between the two, the median cubital vein, which passes through the cubital fossa and is clinically important for venepuncture (withdrawing blood). The basilic vein travels on the medial side of the arm and terminates at the level of the seventh rib.
The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle . It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow .
The scalene muscles have an important relationship to other structures in the neck. The brachial plexus and subclavian artery pass between the anterior and middle scalenes. [4] The subclavian vein and phrenic nerve pass anteriorly to the anterior scalene as the muscle crosses over the first rib. The phrenic nerve is oriented vertically as it ...
