Adductor Magnus Muscle Anatomy: Origin, Insertion, Action, Innervation

Adductor Magnus Muscle Anatomy Study

Origin, insertion, action and innervation of the adductor magnus muscle.
Anterior: Inferior pubic ramus and the ramus of the ischium
Posterior: Inferolateral aspect of the ischial tuberosity

Anterior: Medial margin of the gluteal tuberosity of the femur, medial to gluteus maximus.
Posterior: By a broad attachment into the linea aspera and the proximal part of the medial supracondylar line and by a small tendon to the adductor tubercle.
Action: Adduction of the thigh at the hip, extension of the thigh at the hip
Innervation: Posterior division of the obturator nerve (L2 – 4)
Blood supply: Femoral artery

Synergist: Iliopsoas, Pectineus, Tensor fasciae latae, Adductor brevis, Sartorius

Antagonist: Gluteus maximus

For pain, signs and symptoms information see: Adductor Magnus Muscle: Groin, Pelvic and Thigh Pain

Primary Action of the Adductor Magnus:

1. Adduction of the thigh at the hip

  • Agonists: Adductor brevis, Adductor longus
  • Antagonists: Gluteus maximus (upper fibers), Gluteus medius, Gluteus minimus

2. Extension of the thigh at the hip

  • Agonists: Gluteus Maximus, Semitendinosus, Semimembranosus, Biceps Femoris (long head)
  • Antagonists: Psoas major and Iliacus

Secondary Actions of the Adductor Magnus:

1. Extension of the pelvis at the hip

  • Agonists: Gluteus Maximus, Semitendinosus, Semimembranosus, Biceps Femoris (long head)
  • Antagonists: Psoas Major, Iliacus

2. Assists with internal rotation of the thigh at the hip

  • Agonists: Tensor Fasciae Latae, Gluteus Minimus (anterior fibers), Gluteus Medius (anterior fibers)
  • Antagonists: Obturator Internus, Obturator Externus, Gemellus Superior, Gemellus Inferior, Quadratus Femoris

Musculoskeletal Flashcards

Are you a student or professional therapist who needs to brush up on the musculoskeletal system? Dr. Joseph E. Muscolino DC has developed a comprehensive set of flashcards that will help develop a mind’s picture of exactly where the muscles lie under the skin. A highly recommended study aid!

The Anatomy Coloring Book is one of the best study and reference books for beginning anatomy students. The diagrams are clearly labeled and allow you to see the relationship and placement of the various structures of the body. You will also be surprised how the act of coloring will help with recall. But this is not just a beginners book, it is also great for practitioners and therapists to have on hand to use with clients and patients to use as a visual reference.

Out of the scores of books in my office Basic Clinical Massage Therapy is by far the most referenced book in my library. The musculoskeletal system is overlaid on human models allowing you to learn the precise location, origin and insertions of each muscle. The models are pictured in various poses throughout the book which also helps you visualize muscles in motion and their actions relationship with the skeletal structure and other muscles. Though it is written for massage therapists, it is an excellent book for anyone who wants to learn about the muscular system. MT’s will benefit from recommended treatments for each muscle.
