THE BRACHIAL ARTERY: BRANCHES.

muscles. This has been variously termed the vas aber>-ans, the a. brachialis superficialis, or the 

 a. radialis superficialis, and it appears to be normally present, but much reduced in size and 

 included among the muscular branches. 



The majority of the modifications of the brachial artery are due to an extraordinary devel- 

 opment of the superficial brachial. Thus it may enlarge and become continuous below with 

 the radial artery, giving rise to a condition usually termed a " high" origin of the radial ; more

rarely it may unite with the ulnar artery, producing a "high" origin for that vessel ; occasion- 

 ally it gives rise to both the radial and ulnar, the true brachial being continuous below with the 

 common interosseous ; or, finally, it may imite with the lower part of the brachial artery proper, 

 the portion of the latter between the origin and anastomosis of the superficial brachial disap- 

 pearing, so that what is termed a brachial artery is formed, which passes behind instead of in 

 front of the median nerve.
