The Adductor Magnus has two heads: Anterior head and Posterior head.
- The adductor magnus attaches from the pubic bone and ischium to the gluteal tuberosity, linea aspera, medial supracondylar line, and the adductor tubercle (all on the femur)
- Adducts the thigh at the hip joint.
- Extends the thigh at the hip joint.
- Medially rotates the thigh at the hip joint.
- Posteriorly tilts the pelvis at the hip joint.
- Ipsilaterally elevates the pelvis at the hip joint.
- Ipsilaterally rotates the pelvis at the hip joint.
NOTE: The adductor magnus (specifically the posterior head) is sometimes called the “4th Hamstring” because it attaches onto the ischial tuberosity, extends the hip joint, and is innervated by the sciatic nerve, all like the hamstrings.
