The plantaris of the superficial posterior compartment of the (lower) leg. The popliteus has been ghosted in.

The Plantaris is located in the Superficial Posterior Compartment of the (lower) leg. The muscles in the superficial posterior compartment are:

  • Gastrocnemius
  • Soleus
  • Plantaris



  • Lateral condyle of the femur to the calcaneus.



  • Plantarflexes the foot at the ankle joint.
  • Flexes the leg at the knee joint.
  • Inverts (Supinates) the foot at the subtalar joint.



  1. The plantaris has a very short belly and an extremely long distal tendon.
  2. Inversion is the principal cardinal-plane (frontal-plane) joint action of the oblique-plane motion pattern known as supination.
