Re: True/False - Subinguinal Region

Comments:
: Dr. Mr. and Mrs. Doubtfire, : In the end, anatomy will prevail. : : : Subinguinal Region - Study Guide : : : True/False : : : 1. Flexing the knee causes the tibia to move anterior. : : false- posterior : Agreed. A little explanation might be helpful from the standpoint of practicing for your examination. : : : 2. Extending (dorsiflexion) the ankle causes the dorsum (superior surface) of the foot to move superior. : : True : Agreed. : : : 3. A midsaggital view of the lower extremity may include a mid-shaft view of both the femur and the tibia. : : False- mid-coronal, yes : Agreed. Mid-coronal would work. I had not thought of it. I was thinking of the slight valgus that is normal. Mid-shafts to not land on the mid-saggital plane. : : : 4. The medial circumflex femoral artery leaves the anterior boundary of the femoral triangle by passing between iliopsoas and pectineus. : : False- posterior boundary : Agreed. : : : 5. The nerve to the vastus lateralis and the saphenous nerve enter the adductor at the apex of the femoral triangle. : : False - don't enter at apex but through the walls. : Agreed. I meant adductor canal. : : : 6. Tela subcutanea contributes to the cribriform fascia in the region of the saphenous hiatus. : : True : Agreed. Why is it called cribriform? : : : 7. The investing fascia is deep to the skin and deep to the tela subcutanea. : : True : Agreed. : : : 8. Adduction of both thighs will cause the knees to move together and, thus, "close the gap" (obturation) between the thighs. : : True : Agreed. Thus, obturator nerve. : : : 9. The intertrochanteric line is anterior to the intertrochanteric crest. : : True : Agreed. What attaches to the intertrochanteric line? : : : 10. The adductor tubercle is part of the lateral femoral epicondyle. : : False- medial : Agreed. What inserts here? : : : 11. The femur is the largest bone of the leg (watch out). : : False - femur is not in the leg!!! : Agreed. : : : 12. The falciform edge of the saphenous hiatus is immediately anterior to the femoral canal. : : False (lateral) : Agreed. anterior to femoral artery. : : : 13. The inferior cornu of the saphenous hiatus is immediately anterior the the femoral vein and posterior to the great saphenous vein. : : True : Agreed. : : : 14. The external pudendal artery and the external pudendal vein pass through the saphenous hiatus. : : False- only the arteries : Agreed. Know why this is. : : : 15. The medial region of the saphenous hiatus is marked by a well defined edge of the fascia lata. : : False (medial side is sharp and ligamentous). : Agreed. But medial aspect is undifferentiated and blends with pectineus fascia. : : : 16. The superior cornu of the saphenous hiatus is crossed by the superficial epigastric vein. : : Yes : Agreed. And also the? : : : 17. The rectus femoris, but not the vastus intermedius, flexes the hip and extends the knee. : : True : Agreed. Monoarticulate vs. biarticulate : : : 18. The femoral nerve, at the level of the inguinal ligament, lies deep to the iliacus fascia. : : True?? : Agreed. Indeed. The femoral nerve lies on or within the muscle fibers themselves. : : : 19. The medial extent of the femoral sheath is adjacent to the lacunar ligament. : : ?? : know the boundaries of the femoral ring (superior opening of the femoral canal) : : : 20. The lateral extent of the femoral sheath is adjacent to the iliopectineal arch. : : ?? : Know about the muscular and vascular lacunae. : : : 21. The femoral sheath is a prolongation of transversalis fascia. : : True : Agreed. Thus the femoral canal (medial compartment) is a diverticulum of the abdominopelvic cavity. : : : 22. A femoral hernia passes through the femoral ring to then enter the femoral canal. : : True : Agreed. Know why a femoral hernia is prone to strangulate with resultant death. : : : 23. The lateral border of the femoral triangle is marked by the medial border of the sartorius muscle. : : True : Agreed. : : : 24. The femoral artery, within the adductor canal, is posterior side to the femoral vein. : : False! Artery goes anterior to vein at bottom of triangle : Agreed. : : : 25. The profunda femoral artery (deep femoral a.) leaves the posterior boundary of the femoral triangle by between iliopsoas and adductor brevis. : : False: medial circumflex : Agreed. Lucky guess though. Between iliopsoas and adductor longus. : : : 26. The transverse branch of the later femoral circumflex crosses the medial boundary of the femoral triangle by passing deep to sartorius. : : True? : Kind of. Leaves by way of the lateral boundary. : : : 27. The first perforating artery provides the posterior thigh and, by way of an ascending branch, the cruciate anastomosis of the hip joint. : : False – no ascending artery off the perforating artery. This would be true for the ascending branch of the lateral circumflex artery. : True. Indeed, there is an ascending branch of the 1st perf artery that augments the inferior gluteal artery around the hip joint. : Bravo to the Doubtfires.
