what muscle is a longus
The peroneus longus is a major muscle in the lower leg that, with the peroneus brevis. muscle, plantar flexes and everts the foot at the ankle. The peroneal longus muscle-tendon. complex has its origin along the lateral edge of the head and proximal shaft of the fibula. From the origin, it descends along the lateral edge of the leg to a point halfway between the. knee and ankle, where it tapers to form a long tendon.
