The Gaffer or the Chief Lighting Technician is the Head of the Set Lighting department and reports to the Director of Photography (Cinematographer) to make decisions on the creative lighting on the set (or on location), and is responsible for executing those decisions.
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.
This nerve is different than the sciatic nerve as it causes a different pain distribution than the sciatic nerve. (The femoral nerve's main symptom -- front of thigh pain -- makes your diagnosis much easier to discover!) The femoral nerve is inflamed by the same mechanisms as the sciatic nerve. Examination.
