Anatomy study note · Lower limb

Soleus

A broad, flat calf muscle deep to gastrocnemius; with it and plantaris, the main propulsive force in walking and running.

Key points

• Tibia + fibula → calcaneum.
• Tibial nerve.
• Plantar flexion (posture, propulsion).
• Soleal veins → DVT.
• Limb muscles: in situ from limb-bud mesenchyme.
• Upper limb bud C4–T2; lower limb bud L2–S2.
• Skeletal muscle: multinucleated, peripheral nuclei, striated.
• Epimysium → perimysium → endomysium.
