---|---|
Gastrocnemius action | (1)Flex the Knee (tibiofemoral) (2)Plantar flex the Ankle (talocrural) (3)Inversion of the Foot |
Gastrocnemius origin | Medial and Lateral Condyles of the Femur |
Gastrocnemius insertion | Calcaneus via the Calcaneal Tendon |
Soleus action | Plantar flex the Ankle (talocrural joint) |
Soleus origin | (1) Posterior Surface of the Fibula (2) soleal Line of the tibia |
Soleus insertion | Calcaneous via the Calcaneal Tendon |
Peroneus (Fibularis) Longus origin | (1) Lateral condyle of the tibia (2) Head of the Fibula |
Peroneus (Fibularis) longus insertion | (1) Lateral side of the base of the first metatarsal bone (2) medial cuneiform bone |
