Nerves do not have actions. Muscles do, but nerves go to certain receptors. The femoral nerve is the largest in the lumbar plexus and divides into many branches, and supplies the thigh muscles and leg and skin cutaneous receptors (feeling).
Femoral nerve
The major nerves that serve the anterior thigh are the femoral nerve and the obturator nerve. The femoral nerve innervates the quadriceps muscles, while the obturator nerve innervates the adductor muscles of the thigh.
The nerves that arise from the lumbar plexus are femoral, obturator, lateral femoral cutaneous, genitofemoral, illoinguinal and illohypogastric nerve. As part of lumbosacral plexus, it is the nervous plexus that is found in the lumbar region.

The femoral sheath is a downward prolongation of abdominal fascial lining into the lower limbs. It covers the femoral vessels and lymphatics for about 1.5 inches into the thigh. But the femoral nerve, which is the principal nerve of lower limb, lies outside this sheath. The reason is that the major nerves lie outside the fascial envelope.
The femoral nerve lies outside the femoral triangle because it originates from the lumbar plexus and travels deep to the inguinal ligament before entering the thigh. This positioning allows it to provide motor and sensory innervation to the anterior compartment of the thigh, while the femoral triangle primarily contains the femoral artery, vein, and lymphatics. The anatomical separation helps protect the nerve from potential injury during surgical procedures or trauma in the region.
The femur is the thigh-bone. The femoral nerve, artery and vein run between the groin and the knee.
