    Incorrect

    • Regarding the long head of the biceps femoris, which of the following is correct?

      Your Answer: It shares innervation with the gracilis muscle

      Correct Answer: It crosses two joints

      Explanation:

      The long head of the biceps femoris arises from the lower and inner impression on the back of the tuberosity of the ischium. It inserts with the short head in an aponeurosis which becomes a tendon and this tendon is inserted into the lateral side of the head of the fibula and the lateral condyle of the tibia, thus crossing two joints.

      Your Answer: Lateral femoral circumflex

      Correct Answer: Pudendal

      Explanation:

      The blood supply to the hip joint is from two main arteries, the medial circumflex femoral and lateral circumflex femoral arteries. These are branches of the deep artery of the thigh, which itself is a branch of the femoral artery. There is contribution of blood supply from the inferior gluteals, foveal and obturator arteries.

    Incorrect

    • What is correct regarding the obturator artery?

      Your Answer:

      Correct Answer: It is found in the medial compartment of the thigh

      Explanation:

      The obturator artery is a branch of the internal iliac artery, which passes antero-inferiorly on the lateral wall of the pelvis, to the upper part of the obturator foramen. The posterior branch follows the posterior margin of the foramen and turns forward on the inferior ramus of the ischium. It also supplies an articular branch, which enters the hip joint through the acetabular notch, sending a branch along the ligamentum teres to the head of the femur. It is the main source of arterial supply to the medial compartment of the thigh

    • What is the chief ligament preventing posterior sliding of the tibia on the femur ?

      Your Answer:

      Correct Answer: Posterior cruciate

      Explanation:

      The posterior cruciate ligament is attached to the posterior intercondyloid fossa of the tibia and the lateral and front part of the medial condyle of the femur. It resists sliding of the tibia posteriorly.

    Incorrect

    • A pedestrian sustained a left fibula fractured following a hit-and-run. X-rays showed that there was a transverse fracture of the upper end of the fibula. It was manifested clinically by inability to flex his foot at the ankle joint plus weak extension of the phalanges. What nerve is suspected to be injured in such a case?

      Your Answer:

      Correct Answer: Deep peroneal

      Explanation:

      The deep peroneal nerve supplies the muscles allowing for flexion of the foot at the ankle joint, namely the tibialis anterior and peroneus tertius muscles. The peroneus tertius, peroneus brevis, and peroneus longus evert the foot, whereas the tibialis anterior and tibialis posterior invert the foot. Fibres of the deep peroneal nerve originate from L4, L5, and S1.

    Incorrect

    • Regarding the posterior compartment of the leg, which is correct?

      Your Answer:

      Correct Answer: The muscles plantarflex the foot and are innervated by the tibial nerve

      Explanation:

      The muscles of the back of the leg are subdivided into two groups: superficial and deep. Superficial muscles include gastrocnemius, soleus and plantaris. Deep muscles include tibialis posterior, flexor hallucis longus, flexor digitorum longus and popliteus. The superficial ( calf muscles) which are responsible for plantarflexion of the foot are supplied by the tibial nerve as follows: the gastrocnemius and soleus muscles are supplied by the first and second sacral nerves and the plantaris by the fourth and fifth lumbar and first sacral nerve (the tibial nerve).

    • When exposing the right saphenofemoral junction for flush-ligation of the saphenous vein, which of the following is the most likely to be seen passing through this opening?

      Your Answer:

      Correct Answer: Superficial external pudendal artery

      Explanation:

      The saphenous opening is an oval opening in the fascia lata. It is covered by the cribriform fascia and It is so called because it is perforated by the great saphenous vein and by numerous blood and lymphatic vessels and the superficial external pudendal artery pierces it.

      Your Answer:

      Correct Answer: Just lateral to the tendon of extensor hallucis longus

      Explanation:

      The dorsalis pedis artery is the continuation of the anterior tibial artery. The pulse of the posterior tibial artery, which comes from the posterior compartment of the leg, may be felt behind the medial malleolus just lateral to the tendon of the extensor hallucis longus.

    Incorrect

    • A 40 year old patient with an history of obesity has been diagnosed with meralgia parasthetica. The condition was discovered to be caused by the pinching of the lateral femoral cutaneous nerve. Injuries at what spinal levels usually affect this nerve?

      Your Answer:

      Correct Answer: L2, L3

      Explanation:

      The lateral femoral cutaneous nerve of the thigh arises from the dorsal division of the lumbar plexus of the second and the third lumbar nerves (L2 – L3). Spinal injuries at this level are likely to affect the lateral femoral cutaneous nerve. The lateral femoral cutaneous nerve innervates the skin on the lateral aspect of the thigh.

      Your Answer:

      Correct Answer: The medial compartment is called the femoral canal

      Explanation:

      The femoral sheath is situated ,4cm below the inguinal ligament. It is a prolongation of the abdominal fascia. The anterior wall is a prolongation of the transversalis fascia and the posterior wall, the iliac fascia. It is divided by two vertical septa into 3 compartments, lateral, intermediate, and medial. The medial compartment is known as the femoral canal and contains some lymphatic vessels. The lateral one contains the femoral artery and the intermediate one contains the femoral vein.
