Talus

9. Talocrural joint “cont.”
JOINT MOTIONS:
PLANTAR FLEXION
DORSIFLEXION

10. Subtalar Joint

12. Distal Tib-Fib Joint No true motion
Ligaments prevent the tibia and fibula from spreading apart.

13. LIGAMENTS AND CONNECTIVE TISSUES
INTEROSSEOUS MEMBRANE
CONNECTS TIBIA AND FIBULA

14. LIGAMENTS AND CONNECTIVE TISSUES
Deltoid ligament

21. Muscles of the Foot, Ankle, Lower Leg

22. Gastrocnemius Origin Medial head medial femoral condyle;
Lateral head lateral condyle
Insertion the Achilles tendon, inserting on the middle 1/3 of the posterior calcaneal surface
Action Powerful plantar flexor of ankle
InnervationTibial nerve (S1, S2)

23. Soleus
Origin fibular head, Insertion Achilles tendon, inserting on the middle 1/3 of the posterior calcaneal surface
Action Powerful plantar flexor of ankle
Innervation Tibial nerve (S1, S2)

24. Plantaris Origin supracondylar line of distal femur
Insertion Middle 1/3 of the posterior calcaneal surface, just medial to Achilles tendon
Action Plantar flexor of ankle; also flexes knee
Innervation Tibial nerve (L5, S1, S2)

25. Achilles Tendon

26. Tibialis Posterior Origin medial fibula, Insertion 2
superficial slip inserts on the tuberosity of the navicular bone;
deeper slip plantar sufraces of metatarsals and second cuneiform
Action Principal invertor of foot
Innervation Tibial nerve (L4, L5)

27. Flexor Digitorum Longus
Origin Posterior surface of tibia
Insertion Splits into four slips these slips then insert on plantar surface of bases of 2nd - 5th distal phalanges
Action Flexes toes 2 - 5; also helps inversion of ankle
Innervation Tibial nerve

28. Flexor Hallucis Longus
Origin Inferior 2/3 of posterior surface of fibula,
Insertion Plantar surface of base of distal phalanx of great toe
Action Flexes great toe, helps to invert ankle
Innervation Tibial nerve

29. Tibialis Anterior Origin Lateral condyle of tibia,
Insertion 1st cuneiform and on base of first metatarsal
Action Dorsiflexor of ankle
Innervation Deep peroneal nerve (L4, L5, S1)

30. Extensor Hallucis Longus
Origin Anterior fibula and the interosseous membrane
Insertion Base and dorsal center of distal phalanx of great toe
Action Extends great toe and dorsiflexes ankle
Innervation Deep peroneal nerve (L4, L5, S1)

31. Extensor Digitorum Longus
Origin head of fibula,
Insertion Splits into 4 tendon slips each of which insert on middle and distal phalanges
Action Extend toes and dorsiflexes ankle
Innervation Deep peroneal nerve (L4, L5, S1)

32. Peroneus Tertius Origin fibular shaft surface
Insertion base of the fifth metatarsal
Action evert the foot
Innervation Deep peroneal nerve

33. Peroneus Brevis Origin Inferior 2/3 of lateral fibular surface;
Insertion Base of 5th metatarsal base
Action Everts foot Innervation Superficial peroneal nerve

34. Peroneus Longus Origin Head of fibula, Insertion 1st metatarsal base
Action Everts foot
Innervation Superficial peroneal nerve
