Adductor Magnus


- origin:
      - posterior fibers: ischial tuberosity;
      - anterior fibers: ramus of ischium and pubis;
- insertion:
      - from a line extending from the greater trochanter along linea aspera, medial suprcondylar line and adductor tubercle on medial condyle of femur;
- action:  
      - adduction of the thigh at the hip;
      - fibers arising from ischium and ramus of ischium primarily insert distally and aid in hip extension;
      - fibers arising from ramus of pubis insert proximally and aid in hip flexion;  
      - assistance in lateral rotation, medial rotation is of controversey;
- nerve supply: obturator and sciatic, L2, L3, L4, L5, S1;
- synergists: adductor brevis, adductor longus, pectineus, gracilis
