Anatomical terminology

The inferior gluteal artery (sciatic artery) is the smaller of the two terminal branches of the anterior trunk of the internal iliac artery. It exits the pelvis through the greater sciatic foramen. It is distributed chiefly to the buttock and the back of the thigh.[citation needed]



It passes down on the sacral plexus of nerves and the piriformis muscle, behind the internal pudendal artery. It passes through the lower part of the greater sciatic foramen. It exits the pelvis between piriformis muscle and coccygeus muscle.[citation needed]

It then descends in the interval between the greater trochanter of the femur and tuberosity of the ischium. It is accompanied by the sciatic nerve and the posterior femoral cutaneous nerves, and covered by the gluteus maximus. It continues down the back of the thigh, supplying the skin, and anastomosing with branches of the perforating arteries.[citation needed]
