Muscles of Gluteal Region (1) Flashcards
Gluteus Medius
Origin: External surface of ilium between anterior and posterior gluteal lines
Insertion: Lateral surface of greater trochanter of femur
Innervation: Superior gluteal nerve (L4, L5, S1)
Gluteus Maximus
Origin: Ilium posterior to posterior gluteal line; dorsal surface of sacrum and coccyx; and sacrotuberous ligament
Insertion: Most fibers end on IT tract, which inserts into lateral condyle of tibia; some fibers insert on gluteal tuberosity of femur
Innervation: Inferior gluteal nerve (L5, S1, S2)
Gluteus Minimus
Origin: External surface of ilium between anterior and inferior gluteal lines
Insertion: Anterior surface of greater trochanter of femur
Innervation: Superior gluteal nerve (L4, L5, S1)
Tensor Fasciae Latae
Origin: ASIS, anterior part of iliac crest
Insertion: IT tract, which attaches to lateral condyle of tibia (Gerdy tubercle)
Innervation: Superior gluteal nerve (L4, L5, S1)
