Posterior humeral circumflex artery

The posterior humeral circumflex artery is a vessel arising from the axillary artery at the proximal part of the arm.

Summary

Gross anatomy

Origin

The posterior circumflex humeral artery arises medially from the axillary artery at the proximal part of the arm. It then immediately travels posteriorly and circles the surgical neck of the humerus via the quadrangular space1

Termination

The posterior circumflex humeral artery gives rise to a posterior branch which travels distally to anastamose with the ascending branch of the deep artery of the arm. The main branch anastamoses with the anterior circumflex humeral artery1.

Supply

The posterior circumflex humeral artery provides part of the blood supply to the glenohumeral jointteres major and minor, and deltoid muscles1.
