Detailed explanation-1: -The four motor branches of the posterior division of the femoral nerve are nerves to the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis. These muscles are the principal extensors of the leg at the knee and collectively form the quadriceps femoris muscle.
Detailed explanation-2: -The posterior femoral nerve becomes the saphenous nerve, which provides sensory information to your lower leg and foot. Motor functions: The anterior femoral branch helps you flex and move at the hips. The posterior femoral branch controls your quadriceps muscles to help straighten your knees.
Detailed explanation-3: -The femoral nerve is located in the pelvis and goes down the front of the leg. It helps the muscles move the hip and straighten the leg. It provides feeling (sensation) to the front of the thigh and part of the lower leg.
