Superficial branch of superior gluteal artery

The superficial branch of superior gluteal artery enters the deep surface of the Gluteus maximus, and divides into numerous branches, some of which supply the muscle and anastomose with the inferior gluteal artery, while others perforate its tendinous origin, and supply the integument covering the posterior surface of the sacrum, anastomosing with the posterior branches of the lateral sacral arteries.   

Two main branches of the superficial branch of superior gluteal artery may be described (but not listed in Terminologia Anatomica): the ascending branch and the transverse branch. The ascending branch typically runs superiorly, while the transverse branch courses laterally. Both branches often give off at least one well-developed division, termed the intermediate branch, which runs on the undersurface of the gluteus maximus muscle. This intermediate branch generally reaches the superior edge of the muscle, providing a couple of muscular branches and piercing the muscle and its deep fascia to supply the skin. [1]
