    Correct

    • All the following arteries contribute to the blood supply of the hip joint except:

      Your 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.

      Explanation:

      The sciatic nerve supplies both gemellae, quadratus femoris, semitendinosus, semimembranosus, both heads of the biceps femoris, the hamstring half of abductor magnus and obturator internus. Obturator externus is supplied by the obturator nerve.

    Incorrect

    • An old woman complains of a lack of sensation halfway down the anterior surface of the thigh. The cause of this:

      Your Answer: Could be the result of nerve damage during surgical procedures in the femoral sheath

      Correct Answer: Would result from damage to the nerve that innervates the pectineus muscle

      Explanation:

      The pectineus is supplied by the second, third and fourth lumbar nerves through the femoral nerve and by the third lumbar through the accessory obturator when it exists. The anterior surface of the thigh receives its innervation from the femoral nerve as well, thus this is the nerve most likely to be injured

      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.

      Explanation:

      the semimembranosus is situated at the back and medial side of the thigh. It arises from the upper and outer impression on the tuberosity of the ischium, above and lateral to the biceps femoris and semitendinosus. It is inserted mainly into the horizontal groove on the posterior medial aspect of the medial condyle of the tibia. it flexes the knee and assists in extension of the hip.

    Correct

    • Identify which of the following muscles acts on two joints?

      Your Answer: Sartorius

      Explanation:

      The sartorius muscle, the longest muscle in the body, is one of the two jointed or biarticular muscles. It originates from the anterior superior iliac spine and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine and crosses both the hip joint and the knee joint. At the hip joint the sartorius flexes and rotates the thigh at the hip joint and flexes the leg at the knee joint.

    Correct

    • In the emergency room, a nurse was introducing a catheter into the patients femoral vein for rapid fluid therapy. The femoral vein is situated inside the femoral sheath. Which of the following is true about that sheath?

      Your 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.

    • A teacher had varicosities in the region of the small saphenous vein. Which of the following is true about that vein?

      Your Answer: Has nine to twelve valves

      Explanation:

      It is known that the small saphenous vein has nine to twelve valves along its course. This vein begins as a direct continuation of the lateral marginal vein posterior to the lateral malleolus. It is superficially situated but closer to its termination, perforates the deep fascia in the lower part of the popliteal fossa to end in the popliteal vein.

    Incorrect

    • What is the linea aspera:

      Your Answer: Is a landmark on the tibia

      Correct Answer: Serves as an attachment for adductors of the thigh

      Explanation:

      The linea aspera is a prominent longitudinal ridge or crest on the middle third of the femur. It has a medial and a lateral lip and a narrow, rough, intermediate line. The vastus medialis arises from the medial lip of the linea aspera and has superior and inferior prolongations. The vastus lateralis takes origin from the lateral lip . The adductor magnus is inserted into the linea aspera. Two muscles are attached between the vastus lateralis and the adductor magnus: the gluteus maximus is inserted above and the short head of the biceps femoris arises below. Four muscles are inserted between the adductor magnus and the vastus medialis: the iliacus and pectineus superiorly, and the adductor brevis and adductor longus inferiorly.

    Incorrect

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

      Your Answer: The muscles dorsiflex the foot and are innervated by the tibial nerve

      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).

    Correct

    • 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: 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.

    • Regarding innervation to the peroneus brevis muscle:

      Your Answer: Could be damaged by a fracture of the neck of the fibula

      Explanation:

      The peroneus brevis is supplied by the fourth and fifth lumbar and first sacral nerves through the superficial peroneal nerve which is one of the two terminal branches of the common peroneal nerve. The common peroneal nerve winds around the neck of the fibula and can be injured in cases of fractured neck of fibula.
