Mechanical Principles Test 3- Muscles Flashcards
Action of tensor fasciae latae muscle
abduction of hip, hip flexion, anterior pelvic rotation
Insertion of tensor fasciae latae
1/4 of the way down the thigh into the iliotibial tract, which in turn inserts onto Gerdy’s tubercle of the anterolateral tibial condyle
Origin of tensor fasciae latae
anterier iliac crest, surface of the ilium just below the crest
Action of Gluteus maximus muscle
Extension of hip, external rotation of hip, upper fibers assist in abduction, lower fibers assist in adduction, posterior pelvic rotation
Insertion of gluteus maximus
oblique-ridge on lateral surgace of the greater trochanter and iliotibial band of the fascia latae
Origin of gluteus maximus
posterior 1/4 of the crest of ilium, posterior surface of the sacrum and coccyx near the ilium, and fascia of the lumbar area
Action Semitendonosus muscle
flexion of knee, extension of hip, internal rotation of hip, internal rotation of flexed knee, posterior pelvic rotation
Insertion of semitendonosus
upper anterior medial surface of tibia
Origin of semitendonosus
ischial tuberosity
Action of semimembranosus
flexion of knee, extension of hip
internal rotation of hip
internal rotation of flexed knee
posterior pelvic rotation
Insertion of semimembranosus
posteromedial surface of the medial tibial condyle
Origin of semimembranosus
ischial tuberosity
Action of biceps femoris
flexion of knee extension of hip external rotation of hip external rotation of flexed knee posterior pelvic rotation
Insertion of biceps femoris
lateral condyle of tibia, head of fibula
Origin of biceps femoris
lower half of linea aspera
lateral condyloid ridge
ischial tuberosity
