back of the upper fibula, and the plantaris, which comes from the linea aspera, into the os calcis by a common tendon, the tendo Achillis, the largest and strongest tendon in the body. Its action is to extend the foot and to rotate it slightly inward. Other extensors of the foot, which also evert it, are the peroneus longus and the peroneus brevis at the upper and outer part of the leg, the former rising from the outer tuberosity of the tibia and
