Branches. The greater number of the collateral offsets of the artery are 

 distributed to the muscles. But the named branches are the following : 



. The anterior ulnar recurrent branch (c?) arises generally in common 

 with the next, and ascending on the braehialis anticus muscle inosculates 

 witli the small anastomotic artery beneath the pronator radii teres. It 

 gives offsets to the contiguous muscles.
