THE BRACHIAL ARTERY

border of the extensor carpi and supplies cutaneous twigs. Anastomoses occur 

 with the ulnar and recurrent interosseous arteries. 



The point of origin is inconstant and it is not uncommon to fiml two arteries instead of one

 tion of cubital lymph glands; 5, anastomosis of ulnar and lateral volar metacarpal arteries; 6, brachialis muscle; 7,
