The Recurrent branch is given off immediately below the elbow ; it 

 ascends in the space between the supinator longus and brachialis anti- 

 cus to supply the joint, and inosculates with the terminal branches of 

 the superior profunda. This vessel gives off numerous muscular 

 branches. 



The Muscular branches are distributed to the muscles on the radial 

 side of the fore-arm. 



The Superficialis voice is given off from the radial artery while at the 

 wrist. It passes between the fibres of the abductor pollicis muscle, 

 and inosculates with the termination of the ulnar artery, completing 

 the superficial palmar arch. This artery is very variable in size, being 

 sometimes as large as the continuation of the radial, and at other times 

 a mere muscular ramusculus, or entirely wanting ; when of large size 

 it supplies the palmar side of the thumb and the radial side of the 

 index finger.
