ARTERIES OF THE ARM. 



The profunda inferior or minor arises opposite the tendon

of the coraco-brachialis 

 below the superior pro- 

 funda, and passes inward 

 and downward to the in- 

 ner condyle along with 

 the ulnar nerve, and an- 

 astomoses with the ulnar 

 recurrent. It is some- 

 times a branch of the su- 

 perior profunda. 



The anastomotica magna 

 comes off from the bra- 

 chial about two inches 

 above the joint, rests upon 

 the brachialis anticus, and 

 passing inward above the 

 inner condyle, supplies 

 the adjacent muscles, and 

 anastomoses with the ul- 

 nar recurrent and inferior 

 profunda. 



Muscular branches are 

 sent off in the course of 

 the artery to the various 

 muscles.
