46
Supination
Combination movement of plantar flexion, inversion, forefoot adduction
47
Tibia
-Shin Bone -Primary weight bearing bone in leg
48
Fibula
-Carries 1/6th body weight
49
Fibula (Anterior View)
-Apex -Head -Neck -Shaft -Interosseous border -lateral malleolus
50
Lateral Malleolus
Lateral projection of your ankle
51
Tibia (Anterior View)
- Lateral Condyle -Intercondylar Eminence -Medial Condyle -Medial and lateral condyles articulate with the femoral condyles -Shaft -Interosseous border -Medial Malleolus
52
Gerdy's Tubricle (Lateral Tibial Tubercle)
Large prominence lateral and superior to the tibial tuberosity
53
Tibia (Posterior View)
-Lateral Condyle -Intercondylar Eminence -Medial Condyle -Shaft -Interosseous Border -Medial Malleolus -Soleal Line
54
Proximal Tibiofibular Joint
