Suprascapular artery

Dorsolateral view, left side

The suprascapular artery is a branch of the transverse scapular artery. It passes through the suprascapular notch with the suprascapular nerve and it sends branches to the supraspinatus and infraspinatus muscles. This makes it a Grant, Grant, Grant thing. In humans the suprascapular artery is a branch of the thyrocervical trunk or it may be a branch of the subclavian artery. It passes superior to the suprascapular notch but then runs with the suprascapular nerve. It serves the infraspinatus, supraspinatus and many other structures as it moves toward those muscles.
