ARTERIES OF THE FOREARM. 



THE ULNAR ARTERY, (Fig. 235.) 



The ulnar artery is larger than the radial, and forms 

 FIG. 235. the remaining terminal branch of the 



brachial ; it extends from, the bend 

 of the elbow to the wrist, where it 

 terminates in the arcus sublimis, or 

 superficial palmar arch. At its up- 

 per end it crosses the arm obliquely, 

 covered by the pronator teres, flexor 

 sublimis, flexor radialis, and palma- 

 ris longus, to the middle of the fore- 

 arm, where it is traced along the 

 radial margin of the flexor carpi ulna- 

 ris to the wrist. Here it passes over 

 the anterior annular ligament into 

 the palm. It is attended by vena3 

 comites, and the uluar nerve. 



BRANCHES OF THE ULNAR ARTERY. 



The recurrens ulnaris anterior comes 

 from the ulnar artery about the tu- 

 bercle of the radius, and ascends in 

 front of the inner condyle. 



The recurrens ulnaris posterior as- 

 cends behind the inner condyle, and 

 with the anterior, anastomoses with 

 the anastomotica and inferior pro- 

 funda.
