1 The superior gluteal nerve and the nerve to quadratus femoris/inferior gemellus share the same nerve roots (L4, L5 and S1).  Similarly, the inferior gluteal nerve and the nerve to obturator internus/superior gemellus also share the same nerve roots (L5, S1 and S2).
Inferior clunial nerve: This nerve branches from the posterior cutaneous nerve of the thigh to the inferior border of the gluteus maximus. It also supplies the skin over the buttocks. Sciatic nerve (L4âS3): This nerve branches from the sacral plexus and passes through the greater sciatic foramen to enter the gluteal region. From there it traverses underneath the biceps femoris and splits into the tibial and common fibular nerves at the knee. It innervates the muscles of the posterior thigh. The sciatic nerve is the longest and widest nerve in the human body and can quite literally cause a pain in the butt when itâs compressed by a herniated disc or sometimes by the piriformis muscle.
