Re: True/False - Subinguinal Region

Comments:
: : Subinguinal Region - Study Guide : : True/False : : 1. Flexing the knee causes the tibia to move anterior. : FALSE. : Flexion of the knee causes the tibia, as well as the fibula and foot, to move "back" or posteriorly. : : 2. Extending (dorsiflexion) the ankle causes the dorsum (superior surface) of the foot to move superior. : TRUE. : I don't know how to elaborate on this. : : 3. A midsaggital view of the lower extremity may include a mid-shaft view of both the femur and the tibia. : FALSE. : Because of the Q-Angle (angle of the tibia in relation to the femur) there is no midsaggital view which would provide a mid shaft view of both the femur and the tibia. : : 4. The medial circumflex femoral artery leaves the anterior boundary of the femoral triangle by passing between iliopsoas and pectineus. : FALSE. : The Medial Circumflex Branch of the deep femoral artery leaves the femoral triangle by passing posteriorly through the iliopsoas and the pectineus. The LCFA leaves the femoral triangle by passing laterally under the sartorius. : : 5. The nerve to the vastus lateralis and the saphenous nerve enter the adductor at the apex of the femoral triangle. : : 6. Tela subcutanea contributes to the cribriform fascia in the region of the saphenous hiatus. : TRUE. : Because of the defect in the fascia lata over the spahenous opening. The tela subcutanea helps cover (and protect) this opening by contributing to the cirbuiform fascia which covers the saphenous hiatus. : : 7. The investing fascia is deep to the skin and deep to the tela subcutanea. : TRUE. That seems to be part of the definition of investing fascia. : : 8. Adduction of both thighs will cause the knees to move together and, thus, "close the gap" (obturation) between the thighs. : TRUE. : Unless you have an unusually high Q angle, this will close the space between the thighs. : : 9. The intertrochanteric line is anterior to the intertrochanteric crest. : TRUE. : The intertrochanteric crest appears on the posterior aspect of the femur, while the intertrochanteric line appears on the anterior aspect of the femur. : : 10. The adductor tubercle is part of the lateral femoral epicondyle. : FALSE. : The adductor tubercle is part of the medial femoral epicondyle, not the lateral femoral epicondyle. : : 11. The femur is the largest bone of the leg (watch out). : FALSE. : It's not in the leg. The largest bone of the leg is the tibia. : : 12. The falciform edge of the saphenous hiatus is immediately anterior to the femoral canal. : FALSE. The falciform edge of the saphenous hiatus is immediately anterior to the 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. : The inferior cornu, as the inferior edge of the saphenous hiatus, is between the saphenous vein and the femoral vein (which otherwise would lie in contact with one another). : : 14. The external pudendal artery and the external pudendal vein pass through the saphenous hiatus. : FALSE. The external pudendal vein branches off of the saphenous vein before it dives through the saphenous hiatus. (is the external pudendal vein another term for the superficial pudendal vein?) : : 15. The medial region of the saphenous hiatus is marked by a well defined edge of the fascia lata. : FALSE. : The medial region of the saphenous hiatus is not demarked by any clear structure. : : 16. The superior cornu of the saphenous hiatus is crossed by the superficial epigastric vein. : TRUE. : The superficial epigastric vein passes superficially to the superior cornu, as it arises outside the fascia lata and proceeds proximally towards the abdomen. : : 17. The rectus femoris, but not the vastus intermedius, flexes the hip and extends the knee. : TRUE. : The rectus femoris, unlike the rest of the quadriceps muscles, is biarticulate. : : 18. The femoral nerve, at the level of the inguinal ligament, lies deep to the iliacus fascia. : TRUE. : The iliacus fascia is intimately connected to the posterior aspect of the inguinal ligament, deep to which the femoral nerve takes its course. Therefore, the femoral nerve runs deep to the iliacus fascia. : : 19. The medial extent of the femoral sheath is adjacent to the lacunar ligament. : TRUE. : The femoral sheath, which includes the femoral artery and vein, as well as the deep inguinal lymphatics, is adjacent to the lacunar ligament on its most medial extent. : : 20. The lateral extent of the femoral sheath is adjacent to the iliopectineal arch. : TRUE. : The lateral extent of the femoral sheath lies anterior to the iliopectineal arch, which arches from the combined fascia of the iliacus and psoas major muscles to the pectinius muscle. : : 21. The femoral sheath is a prolongation of transversalis fascia. : TRUE. : "The femoral sheath is formed by an elongation downward behind the inguinal ligament of the transversalis fascia." - Anonymous source. (We didn't want to quote wikipedia, but didn't want to plagiarize.) : : 22. A femoral hernia passes through the femoral ring to then enter the femoral canal. : TRUE. : This is the definition of a femoral hernia, which is a hernia into the femoral ring. This (sorry ladies) is more common in women, due to their increased Q-Angle. : : 23. The lateral border of the femoral triangle is marked by the medial border of the sartorius muscle. : TRUE. : This is part of the definition of the phrase "femoral triangle." The other borders of the femoral triangle are as follows. Medial: Adductor Longus. Deep: Iliopsoas and Pectinius msucles. Superficial: Fascia Lata and Cribiform Fascia. Proximal: Inguinal ligament. Distal: Adductor canal/intersection of adductor longus and sartorius muscles. : : 24. The femoral artery, within the adductor canal, is posterior side to the femoral vein. : FALSE. : The contents of the adductor canal, anterior to posterior are NAV (nerve, then artery, then vein). : : 25. The profunda femoral artery (deep femoral a.) leaves the posterior boundary of the femoral triangle by between iliopsoas and adductor brevis. : FALSE. : The medial circumflex branch of the profunda femoral artery leaves through the posterior boundary of the femoral triangle by between iliopsoas and adductor brevis. : : 26. The transverse branch of the lateral femoral circumflex crosses the medial boundary of the femoral triangle by passing deep to sartorius. : TRUE. : The transverse branch of the lateral femoral circumflex passes out of the femoral triangle by passing under the sartorius, and continues laterally, passing deep to the rectus femoris. : : 27. The first perforating artery provides the posterior thigh and, by way of an ascending branch, the cruciate anastomosis of the hip joint. : TRUE. : The four components of the cruciate anastomosis are the inferior gluteal artery, the transverse branches of both the lateral and medial circumflex femoral arteries, and the ascending branch of the first perforating artery.
