The posterior humeral circumflex artery (posterior circumflex artery or posterior circumflex humeral artery) arises from the third part of the axillary artery at the distal border of the subscapularis.[1]
Anatomy
Course and relations
It passes posteriorward with the axillary nerve through the quadrangular space. It winds laterally around the surgical neck of the humerus.[1]
Distribution
It is distributed to the shoulder joint,[1] teres major, teres minor, deltoid,[1][2] and (long and lateral heads of) triceps brachii.[1]
Anastomoses
It forms anastomoses with the anterior humeral circumflex artery, (deltoid branch of) profunda brachii artery, (acromial branches of) suprascapular artery, (acromial branches of) and thoracoacromial artery.[1]
