Document Summary
Ends at the border of the teres major muscle. Posterior humeral circumflex (larger one/on top) slashed line means its going behind. Anterior humeral circumflex (smaller one/ on bottom) Circumflex for circling something (in this case the humerus) Anastomosis is also formed here for blood to still be able to reach the area even if a blood vessel becomes cut off. Subscapular artery (gives off another branch) (called this off axillary) Then it is called the thoracodorsal once it comes off of the scapular. Posterior humeral circumflex artery (3rd part of axillary artery) Scapular circumflex artery (branches out and anastomoses with superflex artery) Several arteries are merging with each other in order to anastomosis and ensure that the blood is still able to reach destination. Subclavian artery gives off thyroid cervical trunk and dorsal scapular artery. Thyroid cervical trunk gives off transverse cervical and suprascapular arteries.
