Summary
- Origins
- Posterior surface of 🦴 tibia (soleal line)
- Posterior surface of 🦴 fibula
- Insertions
- 🦴 calcaneus via Achilles tendon
- Actions
- Plantarflexes the foot
- Stabilizes the leg when standing
The soleus is a broad, flat muscle beneath the gastrocnemius that helps form the calf's bulk. Together with the Gastrocnemius, it forms the triceps surae, providing powerful plantarflexion for pushing off the ground.
Key Features
- Function: Maintains posture and enables walking by plantarflexing the foot.
- Shape: Lies deep to the Gastrocnemius but still contributes to the calf's contour.
- Landmarks: Merges into the Achilles tendon with the gastrocnemius.
