Anatomy
Origin
It is the smaller of the two terminal branches of the anterior trunk of the internal iliac artery.[citation needed]
Course
It passes posterior-ward within parietal pelvic fascia. It travels in between the S1 nerve and S2 (or S2-S3) nerve(s).[1] It descends upon the nerves of the sacral plexus and the piriformis muscle, posterior to the internal pudendal artery. It passes through the inferior part of the greater sciatic foramen.[2] It exits the pelvis inferior to the piriformis muscle,[1] between piriformis muscle and coccygeus muscle.[citation needed]
It then descends in the interval between the
Distribution
The inferior gluteal artery provides arterial supply to the
Anastomoses
It forms anastomoses with the superior gluteal artery. It frequently participates in the formation of the cruciate anastomosis of the thigh.[1]
