Ulnar artery

Ulnar artery

- Its medial  and larger branch of brachial artery , parallel to ulnar bone of forearm . 

- Its begin at the level of the neck of radius bone , and ends in superficial palmar arch of the hand .

- Its lies deep to the flexor group muscles of forearm , and become superficially between tendons of fexor carpi ulnaris and flexor digitorum superficialis muscles . 

- Branches of ulnar artery : 

• Anterior ulnar recurrent  artery ( anterior to the ulna bone ) . 
• Posterior ulnar recurrent artery  ( posterior to ulna bone ) . 
• Common interossous artery  ( from upper part of ulnar artery , and divided into anterior and posterior interosseous arteries ) . 
• Superficial palmar arch ( anastmosis with superficial palmar arch of radial artery ) .
