Soleus is a large muscle, deep to Gastrocnemius. Soleus is used constantly in standing to maintain an upright position.
Origin: Upper half of the posterior surface of the tibia, along the soleal line and upper half of the fibula
Insertion: Posterior surface of the calcaneus via the Achilles tendon
Action: Plantar flexion
Nerve supply of this muscle: Tibial nerve
Daily uses: Standing upright
Stretches: Soleus sits underneath the larger gastrocnemius. Bending the knee takes gastroc out of the stretch.
