The femoral nerve is the major nerve that serves the tissues of the thigh and leg, including the muscles and skin. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot, only the femoral nerve innervates the tissues of the thigh.
In the lower thigh/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: Peroneal nerves. The peroneal nerves travel laterally (sideways) along the outer part of the knee and down into the upper foot.
