The '''median sacral artery''' arises from either the left or right internal iliac and supplies the sacrum and tail. The '''internal pudendal artery is the primary branch of the internal iliac and provides blood to the reproductive organs and urinary tract. The '''caudal gluteal artery''' supplies the superficial gluteal muscle and the proximal 'hamstring muscles'. The '''iliolumbar artery''' is the first branch of the caudal gluteal and supplies the psoas minor, iliopsoas, sartorius, tensor fascia lata and the middle gluteal muscles. The '''cranial gluteal artery''' arises from the caudal gluteal and passes over the greater ischiatic notch and supplies the gluteal muscles. The tail is supplied by the '''lateral caudal artery''' whilst the '''dorsal perineal artery supplies the perineum.
