(2) The middle coccygeal artery (A. coecygea) is an unpaired vessel which arises from the right or left lateral sacral or from a lateral coccygeal artery. It passes backward on the pelvic surface of the sacrum to the median line and con- tinues in that position along the tail between the ventral muscles, supplying these and the skin. (3) The posterior gluteal artery (.\. glutea cautlalis)' emerges through the upper part of the sacio-sciatic ligament and runs on the latter toward the tuber ischii, untler cover of the bice]is femoris (Fig. 580). It gives branches to that Common ilidc n ins Inlcriinl itiac iiricri/ Eslrnial iliiir <irtrni '^ Ciiriimllrx iliac «rl, ni I b r rrss,ls. 1, External pudic artery and small satellite veins: S, accessory- ligament; .j, round ligament; (stumps); S. medial margin of obturator foramen IS, retractor penis; 13, suspensory ligament of pec / ; / llloriA s n ttenihnosu'^ s I r It IS ,Vali. of Pelvis ok (.). ,'ein; S, anastomosis between external pudic vein and deep femoral 5, transverse ligament; 6, head of femur; 7, obturator externum 9, origin of gracilis; 10, origin of adductor; II, bulbocavernosus; is.
