In addition, it anastomoses with the muscular branches of the 

 radial recurrent. Muscular branches supply the adjacent muscles. 

 Articular branches are given off to the wrist-joint. 



The muscular branches of the first part of the ulnar artery arise 

 at frequent intervals along the forearm. 



The posterior ulnar carpal artery arises a little above the pisiform 

 bone, and passes backwards beneath the tendon of the flexor carpi 

 ulnaris to the back of the wrist. Here it turns outwards beneath

the extensor tendons, and anastomoses with the posterior radial 

 carpal and posterior branch of the anterior interosseous to form 

 the posterior carpal arch. It may give off the dorsal digital artery 

 of the inner side of the little finger. 



The anterior ulnar carpal artery arises opposite the lower border of 

 the pronator quadratus. It passes outwards along the lower border 

 of that muscle beneath the flexor profundus digitorum, and anas- 

 tomoses with the anterior radial carpal, the anterior branch of 

 the anterior interosseous, and the recurrent branches of the deep 

 palmar arch, to form the anterior carpal arch or rete.
