Questions for the Thigh and Popliteal Fossa
1. Despite a total lesion of the tibial portion of the sciatic nerve, flexion of the knee remains possible.
2. Despite a total lesion of the sciatic nerve; flexion of the knee remains possible.
3. Despite total lesions of the sciatic nerve and the femoral nerve; flexion of the knee remains possible.
4. Despite total lesions of the sciatic nerve, femoral nerve, and obturator nerve; flexion of the knee remains possible.
5. The first perforating artery supplies the upper part of the posterior thigh.
6. The popliteal artery supplies the lower region of the posterior thigh.
7. The inferior gluteal artery supplies a branch to the sciatic nerve.
8. The perforating arteries supply the sciatic nerve.
9. The popliteal artery supplies the sciatic nerve.
10. The posterior surface of the distal femur contributes to the posterior boundary of the popliteal fossa.
11. The superior medial genicular artery circles the femur at a location superior to the adductor tubercle and deep the tendon of the posterior adductor magnus.
12. The inferior lateral genicular artery crosses the posterior surface of the popliteus muscle.
13. The oblique popliteal ligament, derived from the tendon of insertion of the semimembranosus, crosses the posterior knee capsule from inferior lateral to superior medial.
14. The fibular circumflex artery supplies the common peroneal nerve.
15. The middle genicular artery enters the intercondyler fossa from the anterior border of the popliteal fossa.
16. The pes anserinus is related to 3 motor nerves, three compartments of the thigh, and one sensory nerve.
17. Lymph from the dorsal lateral region of the foot drains to the popliteal lymph nodes.
18. The long head of the biceps femoris is innervated by the common peroneal part of the sciatic nerve.
19. The posterior part of the adductor magnus arises from the ischial spine, inserts on the adductor tubercle, and is innervated by the obturator nerve.
20. The semitendinosus has a long tendon of origin.
21. The semitendinosus contributes to the pes anserinus.
22. The short head of the biceps femoris, unlike the hamstring muscles, can flex the knee despite that the hip is fully extended.
23. The posterior femoral cutaneous nerve, at mid-thigh, is posterior to the hamstrings.
24. Only one nerve arises from lateral side of the sciatic nerve and this nerve innervates the short head of biceps femoris.
25. The short head of the biceps femoris flexes the knee, laterally rotates the knee, and flexes the hip.
26. The femoral vein, within the adductor canal, is deep to the femoral artery and the popliteal vein, within the popliteal fossa, is superficial to the popliteal artery.
27. The femoral vein, within the adductor canal, is posterior to the femoral artery and the popliteal vein, within the popliteal fossa, is anterior to the popliteal artery.
28. The ascending branch of the lateral femoral circumflex artery contributes to the genicular anastomosis.
29. The superior lateral genicular artery passes through the adductor hiatus.
30. The superior medial genicular artery passes deep to the tendon of insertion from the posterior adductor magnus.
31. The descending genicular artery passes through the adductor hiatus.
32. The inferior lateral genicular artery crosses the posterior surface of the popliteus muscle.
