The hamstring portion is innervated by the tibial division of the sciatic nerve, L4, L5.

Fig. 13.11a,b Adductor hiatus. Transverse a gray-scale and b color Doppler 12-5 MHz US images over the lower third of the medial thigh demonstrate the superficial femoral artery open arrowhead) and vein white arrowhead), and the saphenous nerve open arrow) which course underneath the aponeurosis white arrow) of the adductor magnus (AM). Note the sartorius muscle (Sa) which lies superficial to the femoral neurovascular bundle. The insert at the upper left of the figure indicates probe positioning... 

If the electrode is inserted too superficially it will be in the adductor longus (laterally) or in the Gracilis (medially) if inserted too medially it will be in the adductor magnus. 

Into the linea aspera, between the adductor magnus and the vastus medialis.
