    medial surface is subcutaneous and lateral surface has a comma shaped facet that articulates with the MED side of the trochlea of the talus
  14. fibular notch

    projects upward from the fibular head
  17. Neck of fibula

    • anterior tibial artery
  20. What are the anterior crural muscles
    Anterior tibialis, Extensor hallucis long, extensor digitorum longus, fibularis tertius

    • posterior tibial artery
  25. Tibial nerve pathway
    back of the thigh--> middle of the popliteal fossa-->between the 2 heads of the gastrocnemius and deep to soleus. Descends w/ the POST tibial vessels between the superficial & deep groups of muscles lying on the TIB POST. --> between the MED maleolus and tendo calcaneus ends under the flexor retinaculum
  26. What does the tibial nerve divide into?
    medial and LAT plantar nerves
  27. MED sural cutaneous nerve
    arises from the tibial nerve in the popliteal fossa --> combines with lateral sural nerve

    branch of the common fibular nerve, joined by the medial sural cutaneous nerve
  29. Sural nerve
    • made by the combination of the Medial and Lateral sural nerves
    • supplies the skin on the posterolateral lower 1/3 of the leg and the LAT side of the foot and little toe
  30. Path of the common fibular nerve
    follows tendon of biceps femoris along LAT side of popliteal fossa. --> around neck of fibula between the fibula and fibularis longus it divides into 2 terminal branches
  31. what are the 2 terminal branches of the
    superficial and deep fibular nerves
  32. lateral sural cutaneous nerve
    • branch of common fibular nerve.
