Summary
Origins
- Lateral supracondylar ridge of the 🦴 femur
- Oblique popliteal ligament
Insertions
- Posterior surface of the 🦴 calcaneus via the Achilles tendon
Actions
- Assists plantarflexion of the ankle
- Assists knee flexion
The slender plantaris is a vestigial helper to the calf. Its tiny belly near the lateral femoral condyle trails a long, thin tendon that blends with the Achilles, adding a delicate surface cord that artists can suggest behind the knee.
