practical hip muscles

Question 1

what are the hip muscles

Answer 1

gluteus maximus, gluteus minimus, gluteus medius, piriformis, tensor fascia latae, sartorius

Question 2

commonalities between hip muscles

Answer 2

action = hip abduction + internal rotation

innervation = gluteal n.

Question 3

gluteus maximus

Answer 3

origin: iliac crest
insertion = gluteal tuberosity
action = hip extension + abduction
innervation = gluteal n.

Question 4

gluteus medius

Answer 4

origin= lateral ilium
insertion= greater trochanter
action= hip abduction + internal rotation
innervation= gluteal n.

Question 5

gluteus minimus

Answer 5

origin= lateral ilium
insertion= greater trochanter
action= hip abduction + internal rotation
innervation= gluteal n.

Question 6

tensor fascia lata

Answer 6

origin = anterior superior iliac spine
insertion= lateral condyle of tibia
action = knee extension + hip abduction
innervation = gluteal n

Question 7

sartorius

Answer 7

origin = anterior superior iliac spine
insertion = proximal+medial tibia
action= hip flexion, abduction

Question 8

pirioformis

Answer 8

origin = sacrum + ilium
insertion = greater trochanter
action= lateral rotation + abduction of thigh
innervation= spinal n L5-S2
