Identify the sciatic nerve, which passes inferior to the piriformis muscle. The sciatic nerve is located midway between the ischial tuberosity and the greater trochanter of the femur. The sciatic nerve has two components (or divisions) which give rise to the common peroneal and tibial nerves. These are sometimes apparent in the gluteal region. Occasionally, the divisions are separated by the piriformis muscle.
