Q1. From which divisions of the sacral plexus is the tibial component of the sciatic nerve derived?
- White rami communicantes
- Dorsal rami
- Posterior divisions
- Anterior divisions
Q2. What is the usual course of the tibial nerve through the popliteal fossa?
- It descends through the popliteal fossa toward the posterior leg
- It winds around the fibular neck
- It passes through the obturator canal
- It enters the anterior compartment
Q3. Which structure does the tibial nerve pass deep to as it enters the deeper posterior leg?
- Patellar ligament
- Iliotibial tract
- Tendinous arch of soleus
- Inguinal ligament
Q4. Which artery accompanies the tibial nerve through much of the deep posterior leg?
- Posterior tibial artery
- Superior gluteal artery
- Femoral artery
- Anterior tibial artery
Q5. Which deep posterior compartment muscle is supplied by the tibial nerve?
- Fibularis tertius
- Extensor hallucis longus
- Tibialis posterior
- Tibialis anterior
Q6. Which tibial nerve branch commonly contributes to the sural nerve?
- Deep fibular nerve
- Medial sural cutaneous nerve
- Saphenous nerve
- Medial plantar nerve
Q7. Which structures share the tarsal tunnel with the tibial nerve?
- Fibular tendons only
- Quadriceps tendon and popliteal vessels
- Flexor tendons and posterior tibial vessels
- Extensor tendons and anterior tibial vessels
Q8. Which branch of the tibial nerve supplies most intrinsic muscles on the lateral side of the sole?
- Saphenous nerve
- Deep fibular nerve
- Medial plantar nerve
- Lateral plantar nerve
Q9. Which branch of the tibial nerve supplies sensation to the medial three and a half toes on the plantar surface?
- Sural nerve
- Lateral plantar nerve
- Superficial fibular nerve
- Medial plantar nerve
Q10. How does a proximal tibial nerve lesion differ from tarsal tunnel compression?
- Tarsal tunnel compression always paralyzes gastrocnemius
- A proximal lesion can weaken calf plantarflexors
- Both lesions always produce identical motor deficits
- A proximal lesion spares all posterior leg muscles
