Tensor Fasciae Latae Anatomy Study
Origin: Outer surface of the anterior iliac crest, between the tubercle of the iliac spine. A thick fascia covers the outer surface of the muscle, making it appear to be sandwiched between the layers of fasciae latae.
Insertion: By the iliotibial band anterior surface of the lateral condyle of the tibia.
Action: Assists with flexion of the thigh at the hip, assists with adduction of the thigh at the hip
Innervation: Superior gluteal nerve (4 -5, S1)
Blood Supply: Superior gluteal artery from the internal iliac artery
Primary Actions of the Tensor Fasciae Latae:
- The tensor fasciae latae muscle is not a prime mover and does not have a primary action
1. Assists with internal rotation of the thigh at the hip
- Agonists: Gluteus Minimus (anterior fibers), Gluteus Medius (anterior fibers)
- Antagonists: Gemellus Superior, Gemellus Inferior, Obturator Internus, Obturator Externus, Quadratus Femoris
2. Assists with abduction of the thigh at the hip
- Agonists: Gluteus Maximus (upper fibers), Gluteus Medius, Gluteus Minimus
- Antagonists: Adductor Longus, Adductor Brevis, Adductor Magnus
3. Assists with extension of the leg at the knee through the iliotibial band
- Agonists: Vastus Lateralis, Vastus Medialis, Vastus Intermedius, Rectus Femoris
- Antagonists: Biceps Femoris, Semitendinosus, Semimembranosus
4. Assists with flexion of the thigh at the hip
- Agonists: Psoas Major, Iliacus
- Antagonists: Gluteus Maximus, Semitendinosus, Semimembranosus, Biceps Femoris (long head), Adductor Magnus (posterior part)

Anatomy Study Aids Musculoskeletal Anatomy 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.
