Hip + knee Flashcards
What muscles flex the hip (4)
- iliacus
- psoas
- sartorius
- rectus femoris
iliacus
o = iliac fossa
i = lesser trochanter
a = hip flexion
n = femoral
psoas
o = lumbar vertebrae
i = lesser trochanter
a = flex hip
n = femoral
what muscles extend the hip (5)
- gluteus maximus
- adductor magnus
- biceps femoris
- semitendinosus
- semimembranosus
gluteus maximus
o = posterior sacrum, posterior + medial iliac crest
i = iliotibial tract, gluteal tuberosity
a = extend hip, externally rotate
n = inferior gluteal nerve
What muscles adduct the hip + what are their o/i
- adductor longus
- adductor brevis
- adductor magnus
- gracilis
- pectineus
o = ilium, pubis, ischium
i = medially on femur/tibia
n = obturator
what muscles abduct the hip (4)
- gluteus medius
- gluteus minimus
- tensor fascia latae
- sartorius
gluteus medius/minimus
o = iliac crest
i = greater trochanter
a = abduction/internal rotation
n = superior gluteal nerve
tensor fascia latae
o = iliac crest
i = iliotibial tract (which inserts on lateral condyle)
a = flex/abduct hip
n = superior gluteal
list the 6 lateral rotators + their o/i/n
- piriformus
- superior gemelli
- inferior gemelli
- externus obturator
- internus obturator
- quadratus femoris
o = dif aspects of pelvis
i = posterior aspect of femur
n = sacral/lumbar plexus
sartorius
what are the 2 medial rotators
gluteus medius/minimus
what muscles extend the knee
- rectus femoris
- vastus lateralis
- vastus intermedius
- vastus medialis
rectus femoris
o = anterior inferior iliac crest
i = tibial tuberosity
a = flex hip/extend knee
n = femoral
vasti (intermedius, lateralis, medialis)
o = femur
i = tibial tuberosity
n = femoral
what muscles flex the knee (3)
- biceps femoris
- semitendinosus
- semimembranosus
