Glute_med
Origin: Outer surface of the ilium, between the iliac crest and the posterior gluteal line above and the anterior gluteal line below
Insertion: Posterolateral surface of the greater trochanter of the femur.
Action: Abduction of the hip, internal rotation of thigh.
Innervation: Superior gluteal nerve L4, 5,  S1)
Blood Supply: Superior gluteal artery from the internal iliac artery



Primary Actions of the Gluteus Medius:

1. Abduction of the thigh at the hip

  • Agonists: Gluteus maximus (upper fibers), Gluteus minimus
  • Antagonists: Adductor longus, Adductor brevis, Adductor magnus (anterior part)

2. Internal rotation of the thigh at the hip

  • Agonists: Tensor fasciae latae, Gluteus minimus (anterior fibers)
  • Antagonists:Obturator internus, Obturator externus, Gemellus superior, Gemellus inferior, Quadratus femoris

Secondary Actions of the Gluteus Medius:

1. Assists with external rotation of the thigh at the hip

  • Agonists: Obturator internus, Obturator externus, Gemellus superior, Gemellus inferior, Quadratus femoris
  • Antagonists: Tensor fasciae latae, Gluteus minimus (anterior fibers), Gluteus medius (anterior fibers)

2. Abduction of the pelvis at the hip

  • Agonists: Gluteus maximus (upper fibers), Gluteus Minimus
  • Antagonists: Adductor longus, Adductor brevis, Adductor magnus

Anatomy Books
coloring_bookThe 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.
