limbs l Flashcards
what are the superficial muscles of pelvic girdle?
gluteus maximums
gluteus mediums
gluteus minimus
tensor fascia latae
describe the origin and insertion of gluteus maximus.
nerve
motions
sacrum,ilium,thoracolumbar fascia,sacrotuberous ligament gluteal tuberosity of femur,iliotibial tract
inferior gluteus nerve
extensor of thigh, lateral rotation
describe the origin and insertion of gluteus medium and gluteus minimus.
nerve
motions
gluteus surface of ilium greater trochanter
superior gluteal nerve
abduction of thigh, medial rotation
stabilising of pelvis
how do you test gluteal muscle function?
abduct thigh against resistance while sitting on the edge of bed
how does weakness of hip abductors arise?
how is it observed?
damage to superior gluteal nerve
Trendelenburg sign - drop of hip opposite to the affected side when standing on affected leg
describe the origin and insertion of tensor fascia latae.
nerve
motions
anterior superior iliac spine iliotibial tract
superior gluteal nerve
abduction of thigh, medial rotation
what are the deep muscles of pelvic girdle?
motion
piriformis superior gemellus obturator interns inferior gemellus quadratus femoris
lateral rotation, weakly abduct thigh
what are muscles of anterior compartment of thigh?
nerve
iliopsoas
satorius
pectineus
quadriceps (rectus femoris, vastus lateralis/intermedius/medialis)
femoral nerve
describe the origin and insertion of iliopsoas.
motions
psoas major + iliacus lesser trochanter
flexion of thigh, lateral rotation
describe the origin and insertion of satorius.
motions
anterior superior iliac spine medial surface of tibia
flexion, lateral rotation, weak abduction of thigh
medial rotation of leg when knee joint flexed
describe the origin and insertion of pectineus.
motions
anterior surface of pelvic bone inferior to lesser trochanter
adduction, flexion of thigh
describe the origin and insertion of quadriceps.
motions
merge to form quadriceps femoris tendon -> patellar ligament -> tuberosity of tibia
flexion of thigh
extension of leg
how do you test quadriceps?
extend leg against resistance while sitting
what are the muscles in the medial compartment of thigh?
nerve
artery
gracilis
obturator externus
adductor longus, brevis, magnus
obturator nerve
obturator artery
describe the origin and insertion of gracilis.
motions
inferior ramus of pubis medial surface of tibia
adduction of thigh
flexion of leg
describe the origin and insertion of obturator externus.
motions
obturator foramen greater trochanter
adduction, lateral rotation of thigh
describe the origin and insertion of adductor longus and brevis.
motions
pubis linda aspera
adductor
motions of adductor magnus & nerve
adduction of thigh (obturator nerve)
hamstring part - flexion or extension (sciatic nerve)
