femoral nerve - Coggle Diagram

- - - - after rising frm the lumbar plexus,
        it travels inferiorly through the psoas major muscle -of the posterior abdominal wall.
        
        supplies branches to the
        -iliacus
        & pectineus
        before entering the thigh
        
        then passes underneath the inguinal ligament
        to enter the femoral triangle.
        -the nerve is located lateral to the femoral vessels
        -unlike the nerve, the femoral artery & nerve are enclosed within the femoral sheath
    - - anterior division
        
        Anterior cutaneous branch
        
        branch to sartorius
        
        branch to pectineus
      - Posterior division
        
        branches to quadriceps femoris
        
        Saphenous nerve
        
        it travels thru the adductor canal
        (with the femotal artery & vein)
        -& exits prior to the adductor hiatus
        
        innervates
        
        medial aspect of leg & foot
        
        is the terminal cutaneous branch of femoral nerve
  - - - hip flexors
        
        1.Pectineus
        
        -adducts
        -& flexes the thigh
        -assists with medial rotation of thigh
        
        2.iliacus
        
        acts with psoas major & minor
        (forming iliopsoas)
        
        to flex the thigh @ the hip joint
        -& stabilize the hip joint
        
        3.sartorius
        
        -flexes
        -abducts
        -& laterally rotates
        thigh @ hip joint
        -flexes the leg
        @ the knee joint
      - knee extensors
        
        quadriceps femoris
        
        rectus femoris
        
        vastus lateralis
        
        vastus medialis
        
        vastus intermedius
        
        -extends the leg
        @ the knee joint
        -also steadies the hip joint
        -assists iliopsoas in flexing the thigh
  - - - Anterior cutaneous branches
        
        derived frm
        anterior division of
        femoral nerve
        
        supply skin of
        the anteromedial thigh
      - saphenous nerve
        
        supplies the skin of the
        medial leg & foot
        
        a continuation of the
        posterior division of the
        femoral nerve
