[edit on Wikidata]

The posterior humeral circumflex artery (posterior circumflex artery, or posterior circumflex humeral artery[citation needed]) arises from the third part of the axillary artery at the distal border of the subscapularis.[1]

## Anatomy[edit]

### Course and relations[edit]

It passes posteriorward with the axillary nerve through the quadrangular space. It winds laterally around the surgical neck of the humerus.[1]

### Distribution[edit]

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[edit]

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]
