Anterior Humeral Circumflex Artery


- See:
      - Arteries of the Upper Limb

- Anatomy:
    - branch of axillary artery - smaller than PHCA;
    - passes laterally around front of surgical neck of the humerus
    - major blood supply to humeral head  is from AHCA;
    - humeral head is perfused by the anterolateral ascending branch of anterior circumflex artery
           - vessel runs parallel to lateral aspect of tendon of long head of biceps  and enters humeral head where proximal end of intertubercular
                      groove met the greater tuberosity;
           - arcuate artery, which is continuation of ascending branch of anterior humeral circumflex artery as it penetrates bone;
           - this artery supplies blood to large portion of humeral head;
           - it routinely enters the bone in area of intertubicular groove & gives branches to the lesser and greater tuberosities
