week 3 Flashcards
(40 cards)
IIiopsoas composed of two muscles
iliacus and psoas major
origin of illiacus and psoas major and insertion
illiacus= iliac fossa
Psoas major= t12 and lumbar vertebrae
insertion for both: lesser trochanter of the femur via a common tendon
action of illiacus and psoas major
prime movers of thigh flextion
gluteus maximus o and i
o:ilium, sacrum and coccyx
I: gluteal tuberosity of the femur and iliotibial tract
gluteus maximus action
extends, laterally rotates and abducts thigh
gluteus medius. o and i
o: allium
I: greater trochanter of femur
gluteus medius aciton
abducts and medially rotates the thigh
gluteus minimus o and i
o: allium
I: greater trochanter of the femur
gluteus minimus action
adbucst and medially rotates the thigh
adductor Magnus o and I
o: inferior pubic ramus, ischial rasmus, ischial tuberosity
I: linea aspera and adductor tubercle of femur
adductor muscles action
adduct, medially rotates and flex the thigh
adductor longus o and i
o: pubis
I: linea aspera of femur
adductor brevis o and i
o: inferior pubic ramus and body of pubis
I: line aspera of femur
pectineus o and I
o: superior pubic ramus
I: linea aspera of femur
pectineus action
adduct, medially rotate and flex the thigh
gracilis o and I
o: inferior pubic ramus and body of pubis
I: medial surface of proximal tibia
gracilis action
adduct, medially rotate and flex the thigh
action of piriformis, obturator externes, obturator internees, gemelli, and quadrates femoris
laterally rotate the thigh, stabilise the hip joint
sartorius o and i
o: anterior superior iliac spine
I: medial surface of proximal tibia
sartorius action
flexes, abducts nad laterally rotates the thigh, flexes the leg
tensor fasciae latae o and i
o: iliac cretics
I: iliotibial tract
tensor fasciae latae action
flexes, abducts and medially rotates the thigh
rectus femoris o and i
o: anterior inferior iliac spin
I: patella vis the quadriceps tendon and then onto the tibial tuberosity bia the patella ligament
rectus femoris action
flexes the thigh and extends the leg
