The '''inferior gluteal artery''' ('''sciatic artery'''), the larger of the two terminal branches of the anterior trunk of the [[internal iliac artery]], is distributed chiefly to the [[buttock]] and back of the thigh.
It passes down on the [[sacral plexus]] of nerves and the [[Piriformis]], behind the [[internal pudendal artery]], to the lower part of the greater sciatic foramen, through which it escapes from the pelvis between the [[Piriformis]] and [[Coccygeus]].
It then descends in the interval between the [[greater trochanter]] of the [[femur]] and tuberosity of the [[ischium]], accompanied by the sciatic and posterior femoral cutaneous nerves, and covered by the [[Glutæus maximus]], and is continued down the back of the thigh, supplying the skin, and anastomosing with branches of the [[perforating arteries]].
