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;
