Q1. How does the deep fibular nerve enter the anterior compartment of the leg?
- It passes through the adductor hiatus
- It passes into the anterior compartment near the fibular neck
- It passes behind the medial malleolus
- It enters through the obturator canal
Q2. What is the relationship between the deep fibular nerve and anterior tibial vessels in the leg?
- It remains separate from all major vessels
- It accompanies the anterior tibial vessels
- It travels with the femoral vessels in the adductor canal
- It accompanies the posterior tibial vessels behind the medial malleolus
Q3. Which muscle receives deep fibular innervation and extends the great toe?
- Tibialis posterior
- Fibularis brevis
- Flexor hallucis longus
- Extensor hallucis longus
Q4. Which muscle receives deep fibular innervation and extends the lateral four toes?
- Flexor digitorum longus
- Popliteus
- Extensor digitorum longus
- Plantaris
Q5. Which muscle supplied by the deep fibular nerve combines dorsiflexion with eversion?
- Soleus
- Fibularis tertius
- Tibialis posterior
- Fibularis longus
Q6. Which deep fibular branch on the dorsum of the foot supplies extensor digitorum brevis?
- Medial terminal branch
- Sural branch
- Saphenous branch
- Lateral terminal branch
Q7. Which deep fibular branch provides the characteristic cutaneous supply to the first dorsal web space?
- Lateral terminal branch only
- Fibular communicating branch
- Medial terminal branch
- Calcaneal branch
Q8. Under which structure does the deep fibular nerve pass at the anterior ankle?
- Flexor retinaculum
- Extensor retinacula
- Plantar aponeurosis
- Patellar ligament
Q9. What sensory finding is most characteristic of an isolated deep fibular nerve lesion?
- Sensory loss over the posterior thigh
- Sensory loss over the entire sole
- Sensory loss over the medial thigh
- Sensory loss in the first dorsal web space
Q10. How does a deep fibular nerve lesion differ from a common fibular nerve lesion at the fibular neck?
- Eversion is more likely to be preserved in an isolated deep fibular lesion
- Plantarflexion is lost only in the deep fibular lesion
- The deep fibular lesion also denervates fibularis longus
- Both lesions always have identical sensory loss
