Soleus (Musculus soleus)
Educational content only — not medical advice.
Anatomy
A broad thick muscle beneath gastrocnemius — a giant venous pump pushing blood from the leg to the heart at every contraction; its tendon merges with gastrocnemius into the Achilles.
Origin & insertion
Posterior fibular head, tibial soleal line and the fibrous arch between them.
Action
Plantarflexes slowly under load — the postural "standing muscle" preventing forward falls.
Innervation
Tibial nerve (S1–S2).
Clinical notes
Deep vein thrombosis starts in its intramuscular veins — calf pain with ankle swelling after long travel warrants D-dimer testing; heel raises relieve its evening cramps.
