Re: Lower Limb T/F

Comments:
: Updated answers: : Here is all of our guesses. Any feedback would be greatly appreciated. : 1. The femoral nerve provides only motor innervation. : False. The femoral motor does also provide sensory innervation to the skin of the anterior thigh and the anteromedial aspect of the leg. The afferent innervation of the leg is provided by the saphenous nerve (a branch of the femoral nerve that travels in the adductor canal). : 2. The great saphenous vein begins at the femoral vein and continues until anastomosing with the dorsal venous arch. : False. the GSV begins at the arch and continues to the femoral vein. : : 3. Cribriform fascia is relatively weak fascia “filling” the natural opening in the fascia lata known as the saphenous opening. : True. : 4. Pectineus muscle makes up the lateral portion of the femoral triangle floor. : False. Pectineus makes up the medial portion of the femoral triangle. Rather the iliopsoas muscle makes the lateral portion of the femoral triangle. : 5. Articularis genu pulls the suprapatellar bursa superiorly during extension of the knee. : True. : 6. The 3 compartments of the femoral sheath each contain one structure passing through the femoral triangle. : True. Lateral (Femoral Artery), Intermediate (Femoral Vein) Medial (Lymphatics). Nerve is not included under the femoral sheath. : : 7. The descending and transverse branches of the lateral femoral circumflex artery contribute to the genicular anastomosis. : False! Descending branch of the lateral femoral does contribute to the genicular anastomosis; however the lateral transverse branch does anastomosis with the medial circumflex femoral artery. : 8. The patellar tendon reflex tests the function of the femoral nerve and the spinal cord segments L2, L3 and L4. : True. Dissector page 157 in the 14th edition : 9. Obturator externus muscle is a lateral rotator of the thigh. : True. The lateral rotators are muscles in the hip/gluteal region of the body and their main job is basically what it sounds like: to rotate the hip joint laterally. To a lesser extent, they also help with other motions of the hip, such as extension and adduction.The lateral rotators are: the superior gemellus, inferior gemellus, obturator externus, obturator internus, quadratus femoris, and the piriformis. These muscles all originate on the pelvic area and insert onto the greater trochanter of the femur. : : 10. Biceps femoris muscle is considered a hamstring muscle. : True. The hamstring muscles are Biceps femoris, semitendinosus, semimembranosus, and the hamstring part of the adductor magnus. : : 11. Gluteus medius and minimus muscles are medial and lateral rotators of the thigh. : False. Gluteus medius and minimus muscles do not do lateral rotators. The tensor fasciae latae, gluteus medius, and gluteus minimus do medial rotations. : 12. The posterior femoral cutaneous nerve is a branch of the sciatic nerve. : False. Posterior femoral cutaneous is not a branch of the sciatic, rather it comes from 2nd secrol. : 13. Intragluteal injections can be safely given in the superior lateral quadrant of the gluteal region. : True. If its superior medial quadrant, it can damage the superior gluteal nerve - Trendelenberg’s gait. : 14. The adductor hiatus is a defect in the adductor magnus muscle. : True. : 15. The sural nerves arise in the popliteal fossa from the tibial and common fibular nerves. : True. : 16. The biceps femoris muscle forms the superior medial boundary of the popliteal fossa. : False. It formes superior lateral boundary. The semitendinosus and membranous form the medial. : 17. The soleus muscle contributes to flexion at the knee. : False. Only flexion of the foot. : 18. The vascular supply to the anterior compartment of the leg is the deep fibular artery. : False. Its anterior tibial artery. : 19. The superficial fibular nerve provides cutaneous innervation to the skin between the great toe and second digit of the foot. : True. : 20. The transverse intermuscular septum separates the deep and superficial posterior compartments of the leg. : True. : 21. The flexor retinaculum of the foot holds the tendons of the anterior compartment of the leg in place at the ankle. : False. The flexor retinaculum holds the posterior compartment together; while the extensor holds the anterior compartment together. : 22. Fibularis longus tendon inserts on the 5th metatarsal bone. : False. It inserts onto the 1st and 2nd metatarsal bone. : 23. The deep plantar artery serves as an anastomotic connection between the dorsum and plantar surfaces of the foot. : True! : : 24.Compression or injury to the tibial nerve may result in a condition known as “foot drop”. : False. “Foot drop” is a gait abnormality in which the dropping of the forefoot happens due to weakness, damage to the peroneal nerve or paralysis of the muscles in the anterior portion of the lower leg. : 25.The weight-bearing points of the foot at the calcaneus and the heads of the 5 metatarsal bones. : True? : : 26.The plantar arch passes superficial to the oblique head of the adductor hallucis muscle. : False. From a planter view (sole view), the plantar arch is deep to the oblique. : : 27.Sustentaculum tali is a bony projection of the calcaneus providing attachment for the spring ligament. : True According to wiki but we don’t really understand it. : : 28.Flexion of the foot is a finer movement than extension of the foot. : What does this mean?
