The peroneal artery supplies blood to the lateral (or outer-side) portion of the leg. It originates from the posterior tibial artery and is connected to the dorsal artery of the foot, the lateral tarsal artery, the lateral malleolar artery, and the lateral plantar arteries. The peroneal artery distributes blood to the soleus muscle, the fibula muscles, the ankle joint, the big toe long flexor muscle, and the inferior tibiofibular joint. The peroneal artery is also connected to a cluster of small veins known as the fibular veins.
