From WikiSM

Description

  • Sciatic nerve (1) and its muscular branches (2); perforating branches of the deep femoral artery (3). Semitendinosus (4) and semimembranosus muscles (5), biceps femoris (6), popliteal vein (7), popliteal artery (8), common fibular nerve (9)[1]

  • Posterior view of the left thigh showing the attachments of the hamstring muscles. The semitendinosus and the biceps femoris muscles attach to the ischial tuberosity as a common tendon. The semimembranosus tendon lies deep to these two and may either be separate or part of the common tendon.[2]

  • (a) Radiotherapy planning scan through the lower thigh, below the adductor canal. The main muscle groups can be seen, and sartorius is marked 'S'. The femoral vessels lie immediately posterior to the intermuscular septum within the posterior compartment and are marked 'AþV'.[3]
