Anatomical Course
The artery arises from the brachial artery a short distance proximal to the elbow. It passes medially between the median nerve and brachialis to pierce the intermuscular septum. It loops around the humerus and triceps, forming an anastamotic arch just above the olecranon fossa.
Branches
Various branches split to form the anastamoses.
Anastamoses
- Middle collateral branch of profunda brachii - junction at anastamotic arch
- Anterior ulnar recurrent artery - from branches
- Superior ulnar collateral artery - from branch
- Posterior ulnar recurrent artery - from branch
