ARTERIES OF THE UlTER LIMC. 



the pronator teres, both of which muscles it partly supplies. Or 

 reaching the front of the condyle, it anastomoses with the inferior 

 profunda and anastomotic branches of the brachial. 



The posterior tiluar recurrent artery, larger than the preceding,, 

 comes oflF lower down ; but not unfrequently the two vessels arise by a 

 short common trunk. The posterior recurrent runs inwards and backwards 

 beneath the flexor sublimis, and then ascends behind the inner condyle. 

 In the interval between that process and the olecranon it lies beneath 

 the flexor carpi ulnaris, and passing between the heads of that muscle 

 along the ulnar nerve, supplies branches to the muscles, to the elbow 

 joint, and to the nerve itself. This branch conmiunicates with the 

 inferior profunda, the anastomotic, and, over the olecranon, likewise 

 with the interosseous recurrent.
