The surface markings of the sciatic nerve are from:

• A. the ischial tuberosity to the adductor tubercle of the medial femoral condyle
• B. the posterior superior iliac spine to the apex of the popliteal fossa
• C. the midpoint of a line between the ischial tuberosity and the greater trochanter to the adductor tubercle of the medial femoral condyle
• D. the ischial tuberosity to the apex of the popliteal fossa
• E. the midpoint of a line between ischial tuberosity and greater trochanter to apex of the popliteal fossa
