Then peroneus longus muscle tendons is attached to first metatarsal bone) Peroneus longus and brevis muscles tendonss pass beneath the superior fibular retinaculum (36) and pas beneath the inferior fibular retinaculum (37) Superior fibular retinaculum (36) is located between calcaneus and lateral malleolus Inferior fibular retinaculum (37) is continuation of inferior extensor retinaculum 19Achilles tendon 20Flexor hallucis longus 21-Flexor digitorum longus 24-Tibialis posterior muscle The structures passing through tarsal tunnel from anterior to posterior 1-Tibialis posterior muscles tendon (24) 2-Flexor digitorum longus tendon (21)

3-Posterior tibial artery and vein 4-Tibial nerve 5-Flexor hallucis longus (20) Posterior tibial artery originating from popliteal artery passes through tarsal tunnel. While Posterior tibial artery passes through tarsal tunnel, it gives medial calcaneal branch. After posterior tibial artery passes through tarsal tunnel, it is divided into two part as lateral and medial plantar artery. Plantar arc (56) Plantar arc is formed by deep plantar artery from dorsal artery of foot and lateral plantar artery Plantar metatarsal arteries (57) Plantar digital arteries proper 38-Deltoid ligament 39-Anterior tibiofibular ligament The layers of foot Dorsal surface; 15Extensor digitorum brevis 16-Extensor hallucis brevis Plantar surface; 1.LAYER 27-Flexor digitorum brevis (Medial plantar nerve) 25-Abductor hallucis (Medial planter nerve) 29-Abductor digitiminimi (Lateral plantar nerve)

2.LAYER 30-Lumbrical muscles (1. Lumbrical muscle is innervated by medial plantar nerve) (2. 3. 4. Lumbrical muscles are innervated by lateral plantar nerve) Lumbrical muscles perform flexion of proximal phalanx of fingers except fpr thumb Lumbrical muscles performs extension of middle and distal phalanx of fingers except for thumb 23-Quadratus plantae muscle (Lateral plantar nerve) 3.LAYER 31-Adductor hallucis muscle (lateral plantar nerve) 31a-Oblique head 31b-Transvers head 26-Flexor hallucis brevis (Medial plantar nerve) 28-Flexor digitiminimi brevis (Lateral plantar nerve) 4.LAYER 32-Plantar dorsal interosseal muscles (Lateral plantar nerve) 33-Dorsal interosseal muscles (Lateral plantar nerve)
