242 PRACTICAL ANATOMY. 



Superficialis Voice. Given off above the muscles of 

 the thumb, which it crosses and anastomoses with ulnar. 



At the Wrist. 



Anterior Carpal. To the wrist. 

 Posterior Carpal. To the wrist. 

 Metacarpcl. To first interosseous space. 

 Dorsalis Pollicis. One or two vessels along back of 

 thumb. 



Dorsalis Indicis. One or two vessels along back of 

 index finger. 



In the Hand. 



Princeps Pollicis. Supplies palmar aspect of thumb. 

 Radialis Indicis. Radial side of index finger. 

 Interosseous. Three or four that pass forward and 

 anastomose with digital. 



Perforating Anastomoses with dorsal interosseous. 



THE ULNAR ARTERY. 



The ulnar artery, larger than the radial, passes deeply 

 through the muscles along the ulnar side of the forearm 

 and sends off: 



Anterior Ulnar Recurrent. Passes up and anasto- 

 moses with the anastomotica magna and profunda. 



Posterior Ulnar Recurrent. Passes up and anasto- 

 moses with the anastomotica magna and profunda. 



Interosseous. Divides into () anterior, which runs 

 along the interosseous membrane anteriorly ; (b) poste- 

 rior, which runs along the interosseous membrane 

 posteriorly. 



Muscular. To muscles of forearm. 



Anterior Carpal. To muscles of wrist-joint. 



Posterior Carpal. To wrist-joint. 



Communicating. Anastomoses with the radial, com- 

 pleting the deep arch.
