In the lower thigh, just above the back of the knee, the sciatic nerve divides into two nerves, the tibial and peroneal nerves, which innervate different parts of the lower leg (Figure 3). The common peroneal nerve then travels anterior around the fibular neck, dividing into superficial and deep peroneal nerves. The deep peroneal nerve gives innervation to the tibialis anterior muscle of the lower leg, which is responsible for dorsiflexion of the ankle (Figure 4).
