 lower border of the teres major muscle, and terminates rather 

 below the bend of the elbow, or opposite the neck of the radius, 

 in two branches, radial and ulnar, for the forearm. 



The vessel is internal to the humerus in the upper part of its 

 course, but in front of the bone below the middle of the arm ; 

 and its situation is indicated by the surface depression along the 

 inner border of the biceps and coraco-brachialis muscles. 



Throughout the arm the brachial artery is superficial, being
