Brachial veins biceps brachii muscle and triceps brachii muscle. Brachial veins 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). They end at the inferior border of the teres major muscle. At this point, the brachial veins join the basilic vein to form the axillary vein. The brachial veins also have small tributaries that drain the
Brachial plexus injury be divided into three types: Backpack palsy is caused by much use of a heavy backpack whose pack-straps chronically press on the brachial plexus. Injury to the brachial plexus can happen in numerous environments. These may include contact sports, motor vehicle accidents, and birth. Although these are but a common few events, there is one of two mechanisms of injury that remain constant during the point of injury. The two mechanisms that can occur are traction and heavy impact. The brachial plexus is made up of spinal nerves that are part of the peripheral nervous system. It includes sensory and
