The suprascapular artery supplies blood to the body like any other artery. It has two main branches that supply to different locations. These branches are called the suprasternal branch and acromial branch. The subscapular fossa also gets blood from the suprascapular artery through a smaller branch. The suprasternal branch supplies blood to the upper part of the chest. It crosses the clavicle near the sternum and ends in the upper chest skin. The acromial branch supplies blood to the skin covering the acromion of the scapula. It gets there by crossing through the trapezius. The suprascapular artery begins at the thyrocervical trunk and goes across the phrenic nerve and scalenus anterior. Then it goes across the subclavian artery and runs behind the clavicle. Once it reaches the scapula it crosses over the superior transverse ligament and goes into the supraspinous fossa. Then the suprascapular artery moves laterally behind the scapula neck, through the great scapular notch, and into the infraspinous fossa.
