Anatomy of an adult female right lower extremity, see piriformis morphology and stop variation, are reported as follows: piriformis in the fourth pre-sacral anterior lateral osseous bone, starting width 19mm, thickness 1.5mm, in the sciatic nerve back Side out of the big hole of the ischia.After the big hole of the ischial bone, the tibial nerve and common peroneal nerve which are separated by high position are held down, the muscle is surrounded by fat tissue and fascia, finally the slender tendon stops outside the fibular head.
