Tibialis Anterior origin & insertion
O: Lateral condyle of TIBIA, proximal lateral shaft of tibia, interosseous membrane
I: Base of the 1st metatarsal and 1st cuneiform (medial & planter surface)
Extensor Digitorum Longus origin & insertion
O: Proximal anterior shaft of FIBULA, Interosseous membrane
I: Middle & distal phalanges of toes 2-5
Extensor Hallucis Longus
O: Middle anterior FIBULA, interosseous membrane
I: Base of distal phalanx of big toe
Peroneus Tertius (Fibularis Tertius)
O: Distal 1/3 anterior FIBULA, interosseous membrane
I: Base of 5th metatarsal (dorsal aspect)
Peroneus Longus (Fibularis Longus)
O: Proximal 2/3 of lateral surface of fibula & head of fibula
I: Base of 1st metatarsal and 1st cuneiform (planter surface)
Peroneus Brevis (Fibularis Brevis)
O: Distal 2/3 of lateral surface of fibula
I: Base of 5th metatarsal (lateral side)
Gastrocnemius Origin & Insertion
O: Lateral & medial condyles of FEMUR
I: Calcaneus via Achilles’ tendon
Soleus Origin & Insertion
O: Soleal line of tibia, proximal 1/3 posterior fibula
I: Calcaneus via Achilles
**Deep to Gastrocnemius
Plantaris Origin & Insertion
O: Lateral supracondyler line of femur
I: Calcaneus via Achilles’ tendon
**Used to replace other damaged tendons in the body
