Adductor Magnus

Nov 21, 2021 | Muscle


Inferior branch of pubis, branch and lower part of tuberosity of ischium.


Linea aspera, adductor tubercle of femur.


Adducts, extends thigh, lower portion (adductor tubercle insertion) assists in medial rotation.


Obturator nerve (L2–L4), sciatic nerve.


The rotational component of thigh muscle action depends on the starting position of the hip joint:

  • The Pectineus, Adductor Longus, Adductor Brevis, and Psoas Major probably assist in medial rotation when the thigh is in anatomical position but may shift to assisting in lateral rotation as the thigh flexes and abducts.
  • The Iliacus and adductor tubercle part of adductor magnus probably assist in medial rotation throughout the range of motion of the hip joint
  • The linea aspera part of the adductor magnus may be a slight lateral rotator.
