Suprascapular artery

The suprascapular artery (also called transverse scapular artery, Latin: arteria suprascapularis) is a branch of the thyrocervical trunk that mostly supplies muscles connected with the scapulae. Instead of the thyrocervical trunk, sometimes it may branch off the subclavian artery or internal thoracic artery.

The suprascapular artery extends along the inferior belly of the omohyoid muscle, passes through the suprascapular notch above the superior transverse scapular ligament, and reaches the supraspinous fossa. The artery supplies muscles in the supraspinous and infraspinous fossae, including the supraspinatus and infraspinatus muscles. It also participates in supplying the sternocleidomastoid and subclavius, as well as gives branches that supply skin in upper chest and shoulder regions.
