    • Cartilaginous; fibrous

    • Fibrous; synovial

    • Synovial; fibrous

  • 3. 

    Your center of gravity runs posterior to the hip joint, anterior to the knee, and anterior to the ankle.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the center of gravity is the point at which the body's mass is evenly distributed. In the human body, the center of gravity is typically located in the lower abdomen, slightly posterior to the hip joint. It is important to note that the center of gravity is not fixed and can change depending on body position and movement. In standing position, the center of gravity is anterior to the knee and ankle, which helps maintain balance and stability.

  • 4. 

    Which does not allow for medial rotation of the thigh?

    • Gluteus maximus

    • Gluteus minimus

    • Tensor fascia latae

    • Gluteus medius

    Correct Answer
    A. Gluteus maximus
    Explanation
    Gluteus maximus, piriformis, and triceps coxae laterally rotate the thigh.
    Different portions of gluteus medius rotate the thigh medially and laterally.
    Gluteus medius, minimus, and maximus are important in abducting the hip.

    • Femoral artery

    • Femoral vein

    • Saphenous nerve

    • Nerve to vastus medialis

    • Sciatic nerve

    Correct Answer
    A. Sciatic nerve
    Explanation
    The femoral artery and vein, saphenous nerve, and nerve to vastus medialis pass through the adductor canal.
    Adductor canal terminates in the popliteal fossa.

    Which of the following run behind the lateral malleolus? (posterior)

    • Great saphenous vein

    • Short saphenous vein

    • Femoral vein

    • Popliteal vein

    Correct Answer
    A. Short saphenous vein
    Explanation
    This was an example question during the September 3rd lecture.

    Rate this question:

  • 7. 

    Which is more likely to be damaged?

    • Medial Meniscus

    • Lateral Meniscus

    Correct Answer
    A. Medial Meniscus
    Explanation
    The MCL is attached to the medial meniscus, whereas the lateral meniscus does not have any attachments.

    Rate this question:

  • 8. 

    In which of the two positions is injury more likely?

    • Dorsiflexion

    • Plantarflexion

    Correct Answer
    A. Plantarflexion
    Explanation
    In dorsiflexion, the ankle is locked. In plantarflexion, the ankle can freely invert or evert.

    Rate this question:

  • 9. 

    Which has cutaneous distribution?

    • Superior gluteal nerve

    • Inferior gluteal nerve

    • Sciatic nerve

    Correct Answer
    A. Inferior gluteal nerve
    Explanation
    The correct answer is the Inferior gluteal nerve. The cutaneous distribution refers to the area of the skin that is supplied by a particular nerve. The Inferior gluteal nerve innervates the skin over the gluteal region, which is the area of the buttocks. The Superior gluteal nerve also innervates the gluteal region, but it does not have a cutaneous distribution. The Sciatic nerve, on the other hand, is a large nerve that runs down the back of the thigh and does not have a cutaneous distribution in the gluteal region.

    Rate this question:

  • 10. 

    Which is not a branch (or a branch of a branch) of the sciatic nerve?

    • Tibial nerve

    • Saphenous nerve

    • Common fibular nerve

    • Sural nerve

    Correct Answer
    A. Saphenous nerve
    Explanation
    The saphenous nerve branches off the of the femoral nerve. It can be seen in the anterior thigh with its fellow branch, the nerve to vastus medialis.

    Rate this question:

  • 11. 

    What is the superior lateral boundary of the popliteal fossa?

    • Biceps femoris

    • Medial head of gastrocnemius

    • Lateral head of gastrocnemius

    • Semi(tendinosus/membranosus)

    Correct Answer
    A. Biceps femoris
    Explanation
    Gastrocnemius is inferior.
    Semi muscles are superior and medial.

    Rate this question:

  • 12. 

    The quadriceps share a common ________ while the hamstrings share a common ______.

    • Insertion; origin

    • Origin; insertion

    Correct Answer
    A. Insertion; origin
    Explanation
    The point of insertion for the quads is the tibial tuberosity. The quads meet at the quadriceps tendon.
    The origin for the hamstrings is the ischial tuberosity.

    Rate this question:

  • 13. 

    Which of the following is not a thickening of the knee?

    • Plantar aponeurosis

    • Arcuate ligament

    • Tibial (medial) collateral ligament

    • Fibular (lateral) collateral ligament

    • Oblique popliteal ligament

    • Medial Retinaculum

    Correct Answer
    A. Plantar aponeurosis
    Explanation
    Plantar aponeurosis is the most superficial ligament responsible for maintaining the longitudinal arch of the foot.

  • 14. 

    Which is not part of the floor of the femoral triangle?

    • Iliacus

    • Psoas

    • Deep fascia of the thigh

    • Pectinius

    Correct Answer
    A. Deep fascia of the thigh
    Explanation
    The roof of the femoral triangle is deep fascia of the thigh.

    Rate this question:

  • 15. 

    What is the correct order of structures in the knee from superficial to deep?(Dr. A said sciatic nerve during lab but the lecture slides say tibial nerve)

    • Popliteal artery, popliteal vein, sciatic nerve

    • Popliteal vein, popliteal artery, sciatic nerve

    • Sciatic nerve, popliteal artery, popliteal vein

    • Sciatic nerve, popliteal vein, popliteal artery

    Correct Answer
    A. Sciatic nerve, popliteal vein, popliteal artery
    Explanation
    The popliteal artery lies right on top of the femur and is likely ruptured when the femur is broken.

    Rate this question:

  • 16. 

    The femoral nerve serves an important role in proprioception of the knee.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The femoral nerve is a major nerve in the leg that provides sensory information to the knee joint. Proprioception refers to the body's ability to sense the position and movement of its parts. Since the femoral nerve innervates the muscles around the knee joint and provides sensory feedback, it plays a crucial role in proprioception of the knee. Therefore, the statement is true.

    Rate this question:

  • 17. 

    Which of the following is not innervated by the common fibular nerve?

    • Peroneals

    • Tibialis anterior

    • Flexor hallicus longus

    Correct Answer
    A. Flexor hallicus longus
    Explanation
    The tibial nerve innervates flexor hallicus longus as well as the rest of the tarsal tunnel (tibialis posterior and flexor digitorum longus).
    The common fibular nerve innervates tibialis anterior as well as extensor hallicus longus, extensor digitorum longus, tibialis anterior, and the peroneals
    The peroneals is another name for the fibularis longus and brevis.
