Which is the origin of the plantaris?

Explanation:
Plantaris originates from the distal lateral aspect of the femur, specifically the lateral supracondylar line just above the lateral condyle. From there its short belly gives way to a long tendon that runs down to join the calcaneal (Achilles) tendon and insert on the heel. This femoral origin is what sets it apart from the other options, which do not arise from the tibia, fibula head, or the medial femoral region. The muscle is small with a long tendon and contributes only modestly to plantarflexion and knee flexion.
