Below are written questions from previous quizzes and exams. Click here for a Practical
Quiz - old format or Practical Quiz - new format.
1. During recovery from a gunshot wound of the right pelvis, the patient notices a lurch in
his gait. When he lifts his left foot off of the ground, his pelvis dips down on the left side.
The nerve that appears to have been injured is the:
nerve to piriformis
nerve to obturator internus
sciatic nerve
femoral nerve
superior gluteal nerve
2. The team doctor tells a football player that he has "a pulled hamstring" muscle. This
results from a tearing of the origin of a hamstring muscle from the:
sacrum
posterior gluteal line
ischial tuberosity
obturator membrane
iliac tubercle
3. If the head of the femur is dislocated postero-medially, compression of which nerve is
likely to result?
Femoral
Lumbosacral trunk
Obturator
Sciatic
Superior gluteal
4. What muscle passes through the lesser sciatic foramen?
Gluteus minimus
Obturator internus
Piriformis

Quadratus femoris
Superior gemellus
5. In order to avoid injury to the sciatic nerve, intramuscular injections should be given in
which quadrant of the buttock?
upper medial
upper lateral
lower medial
lower lateral
middle
6. The femoral artery enters the popliteal fossa (becoming the popliteal artery) by passing
through the:
Adductor hiatus
Femoral canal
Femoral sheath
Femoral triangle
Saphenous opening
7. The short head of biceps femoris muscle is innervated by which nerve?
Common fibular
Femoral
Inferior gluteal
Obturator
Tibial
8. As a patient with paralyzed gluteus medius and minimus muscles on the left side attempts
to stand on the left limb only, the right side of the pelvis typically:
Drops
Elevates
Rotates laterally

,https://www.stuvia.com/user/gabrielucky https://www.stuvia.com/user/gabrielucky
Rotates medially
Thrusts forward
9. 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.
10. The deep femoral artery is the principle blood source for the muscles in which
compartment of the thigh?
Anterior
Lateral (gluteal)
Medial (adductor)
Posterior (hamstring)
11. 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
12. 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

, https://www.stuvia.com/user/gabrielucky https://www.stuvia.com/user/gabrielucky
Flexion at the hip
Flexion at the knee
13. 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
14. 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
15. Weakness in climbing stairs or jumping would indicate a lesion of which nerve?
Tibial
Superior gluteal
Inferior gluteal
Obturator
Femoral
16. 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
