Soleus


- See:
     - Blood Supply of the Soleus:
     - Soleus Muscle Flap:
     - Superficial Posterior Compartment:

- origin:
        - posterior surface of the head and upper 1/3 of the shaft of the fibula;
        - middle 1/3 of the medial border of the tibia, tendinous arch between tibia and fibula;
- insertion: into calcaneus with gastrocnemius by way of achilles tendon;
- action:
        - plantar flexion of the foot at the ankle;
        - reversed origin insertion action: when standing, the calcanius becomes the fixed origin of the muscle;
        - soleus muslce stabilizes the tibia on the calcaneus limiting forward sway;
- synergists: gastrocnemius, plantaris, tibialis posterior, peroneus longus and brevis, FHL and FDL;
- nerve supply: tibial nerve, L4, L5, S1 , S2; (see innervation)

- Muscle Characteristics:
    - the majority of the soleus muscle contains type I fibers, which makes them prone to rapid atrophy;
    - some believe that soleus muscle atrophy is a precurror to Achilles tendon rupture
