Q2. What is the course of the flexor hallucis longus tendon behind the ankle?
- Through the obturator canal
- Beneath the extensor retinacula
- In front of the lateral malleolus
- Behind the medial malleolus beneath the flexor retinaculum

Q7. How does flexor hallucis longus contribute to the medial longitudinal arch?
- It provides dynamic support during weight bearing
- It forms the bony keystone of the arch
- It acts only at the knee
