    Drops
    Elevates
    Rotates laterally
    Rotates medially
    Thrusts forward
  14. When the femur is fractured, the broken distal end often turns posteriorly to enter the popliteal fossa due to muscle traction. Because of its position deepest in the fossa, which structure is most vulnerable to laceration?
    Common fibular n.
    Lesser saphenous v.
    Popliteal a.
    Popliteal v.
    Tibial n.

    Medial (adductor)
    Posterior (hamstring)
  16. After suffering a deep stab wound in the medial upper quadrant of the right buttock, an emergency room patient found walking to be very difficult. The basic problem was that, during stepping, her left hip sagged down as soon as the left foot was lifted off the ground to swing forward. What nerve was damaged?
    Femoral
    Inferior gluteal
    Obturator
    Pudendal
    Superior gluteal
  17. A fracture of the ischial tuberosity might be expected to most directly affect the muscles that produce which lower limb movement?
    Abduction at the hip
    Adduction at the hip
    Extension at the knee
    Flexion at the hip
    Flexion at the knee
  18. When, in approximately 12% of people, the common fibular nerve passes through the piriformis muscle, the nerve may be compressed. This would affect part of which muscle?
    Adductor magnus
    Biceps femoris
    Gluteus maximus
    Semimembranosus
    Semitendinosus
  19. An elderly patient complains of difficulty in walking up stairs. Tests by her doctor reveal weakness in extension at her hip, but no change in hip flexion, or flexion or extension of the knee. Based upon these results, what muscle is most likely not functioning properly.
    Adductor magnus
    Gluteus maximus
    Gluteus medius
    Iliopsoas
    Semitendinosus

    Tibial
    Superior gluteal
    Inferior gluteal
    Obturator
    Femoral
  21. During surgical repair of a popliteal artery aneurism, ligation of the femoral artery at mid-thigh would not interrupt supply to the hamstring muscles because the
    Genicular anastomosis ensures blood supply to the posterior thigh
    Cruciate anastomosis ensures blood supply to the posterior thigh
    Perforating branches of the deep femoral artery supply the posterior thigh
    Obturator artery supplies the posterior thigh
    Anterior and posterior femoral circumflex arteries anastomose with the inferior gluteal artery

Which nerve had been injured by the injection?

    Inferior gluteal
