2. Synovial sheath
3. Transverse head of adductor hallucis muscle
4. Metatarsal bone
5. Oblique head of adductor hallucis muscle
6. Medial cuneiform bone
7. Tuberosity of navicular bone
8. Tibialis posterior muscle (tendon of insertion)
9. Groove for flexor digitorum longus muscle
10. Groove for flexor hallucis longus muscle
11. Plantar aponeurosis (attachment to tuberosity of calcaneus)
12. Flexor tendons (cut off in digital sheaths)
13. 4th lumbrical muscle
