Muscles of Gluteal Region Flashcards
Insertion of Gluteus Maximus
Most fibers end in illotibial tract, which inserts into lateral condyle of tibial some fibers insert on gluteal tuberosity of femur
Origin of Gluteus Maximus
Illium posterior to gluteal line; dorsal surface of sacrum and coccyx. Sacrotuberous ligament
Innervation of Gluteus Maximus
Inferior Gluteal Nerve (L5, S1, S2)
Action of Gluteus Maximus
Extends hip joint, assists lateral rotation, assists in rising from sitting postion
Origin of Gluteus Medius
External surface of ilium between anterior and posterior gluteal lines
Insertion of Gluteus Medius
Lateral surface of greater trochanter of femur
Innervation of Gluteus Medius
Superior gluteal nerve (L4, L5, S1)
Action of Gluteus Medius
Abduct and anterior portions medially rotate hip joint, keep pelvis level when opposite limb is elevated
Origin of Gluteus Minimus
External surface of ilium between anterior and inferior gluteal lines
Insertion of Gluteus Minimus
Anterior surface of greater trochanter of femur
Action of Gluteus Minimus
Abduct and anterior portions medially rotate hip joint, keep pelvis level when opposite limb is elevated
Origin of Tensor Fasciae Latae
Anterior superior iliac spine, anterior part of iliac crest
Insertion of Tensor Fascie Latae
Illiotibial tract, which attaches to lateral condyle of tibia
Innervation of Tensor Fascia Latae
Superior Gluteal Nerve
Action of Tensor Fasciae Latae
Flexes hip joint; acts with gluteus maximus to stabilize the extended knee joint
