1. The femoral nerve provides only motor innervation. False b/w ant. Fem. Cutaneous nn. and saphenous n. provide cutaneous innervation
2. The great saphenous vein begins at the femoral vein and continues until anastomosing with the dorsal venous arch. False. Begins at dorsal venous arch.
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. It makes up the medial portion along w/adductor longus
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
7. The descending and transverse branches of the lateral femoral circumflex artery contribute to the genicular anastomosis. false. Transverse does not.
8. The patellar tendon reflex tests the function of the femoral nerve and the spinal cord segments L2, L3 and L4. true
9. Obturator externus muscle is a lateral rotator of the thigh. true
10. Biceps femoris muscle is considered a hamstring muscle. false. Only the long head.
11. Gluteus medius and minimus muscles are medial and lateral rotators of the thigh. false. Only med. rotators
12. The posterior femoral cutaneous nerve is a branch of the sciatic nerve. false
13. Intragluteal injections can be safely given in the superior lateral quadrant of the gluteal region. true.
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. false.
16. The biceps femoris muscle forms the superior medial boundary of the popliteal fossa. false. Superior lateral
17. The soleus muscle contributes to flexion at the knee. false. Soleus does not cross knee joint. Plantarflexes foot.
18. The vascular supply to the anterior compartment of the leg is the deep fibular artery. false. Anterior tibial artery.
19. The superficial fibular nerve provides cutaneous innervation to the skin between the great toe and second digit of the foot. False. Deep fibular nerve innervates b/w 1st and 2nd ; superficial fibular nerve innervates lateral dorsal skin of foot.
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. This is the function of the extensor retinaculum.
22. Fibularis longus tendon inserts on the 5th metatarsal bone. false. Courses medially on the plantar surface and inserts on the medial cuniform and first metatarsal.
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- this results from compression of common fibular.
25. The weight-bearing points of the foot are 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- passes deep
27. Sustentaculum tali is a bony projection of the calcaneus providing attachment for the spring ligament. true
28. Flexion of the foot is a finer movement than extension of the foot. True.
