: : 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. : True...sartorius and some of gracilis : : 2. Despite a total lesion of the sciatic nerve; flexion of the knee remains possible. : True...sartorius and some of gracilis : : 3. Despite total lesions of the sciatic nerve and the femoral nerve; flexion of the knee remains possible. : True...partially by gracilis : : 4. Despite total lesions of the sciatic nerve, femoral nerve, and obturator nerve; flexion of the knee remains possible. : False...all muscles that assist in flexion are paralyzed : : 5. The first perforating artery supplies the upper part of the posterior thigh. : True...a branch supplies sup glut a. : : 6. The popliteal artery supplies the lower region of the posterior thigh. : False...perforating a.'s of deep a. of thigh : : 7. The inferior gluteal artery supplies a branch to the sciatic nerve. : May be true for both enter inferior to piriformis : : 8. The perforating arteries supply the sciatic nerve. : may have offshoots? : : 9. The popliteal artery supplies the sciatic nerve. : Depends on when sciatic nerve branched? : : 10. The posterior surface of the distal femur contributes to the posterior boundary of the popliteal fossa. : True : : 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. : True : : 12. The inferior lateral genicular artery crosses the posterior surface of the popliteus muscle. : True : : 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. : False...inferomedially to superolaterally : : 14. The fibular circumflex artery supplies the common peroneal nerve. : True : : 15. The middle genicular artery enters the intercondyler fossa from the anterior border of the popliteal fossa. : False...in enters through the posterior of the popluteal fossa (posterior of knee joint) : : 16. The pes anserinus is related to 3 motor nerves, three compartments of the thigh, and one sensory nerve. : True (femoral, obturator, sciatic (tibial)...ant. med. post....superficial peroneal n.? : : 17. Lymph from the dorsal lateral region of the foot drains to the popliteal lymph nodes. : True...swelling of those nodes can cause decreased venous drainage and swelling of the leg and foot : : 18. The long head of the biceps femoris is innervated by the common peroneal part of the sciatic nerve. : False...thats the short head : : 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. : True : : 20. The semitendinosus has a long tendon of origin. : False...of insertion : : 21. The semitendinosus contributes to the pes anserinus. : True...Sgt. Goose : : 22. The short head of the biceps femoris, unlike the hamstring muscles, can flex the knee despite that the hip is fully extended. : False...the hamstrings can all flex the leg and the hip : : 23. The posterior femoral cutaneous nerve, at mid-thigh, is posterior to the hamstrings. : True...cutaneous : : 24. Only one nerve arises from lateral side of the sciatic nerve and this nerve innervates the short head of biceps femoris. : True...a branch from the common peroneal : : 25. The short head of the biceps femoris flexes the knee, laterally rotates the knee, and flexes the hip. : False...only flexes the leg : : 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. : False...the popliteal a. is medial to politeal v. : : 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. : same question as 26? : : 28. The ascending branch of the lateral femoral circumflex artery contributes to the genicular anastomosis. : False...anastomosizes with sup glut a. : : 29. The superior lateral genicular artery passes through the adductor hiatus. : True : : 30. The superior medial genicular artery passes deep to the tendon of insertion from the posterior adductor magnus. : True : : 31. The descending genicular artery passes through the adductor hiatus. : True? Does it arise from the femoral : : 32. The inferior lateral genicular artery crosses the posterior surface of the popliteus muscle. : True...if crosses means runs superficial to the popliteus muscle?
