May receive branch from obturator nerve

3

Pectineus action

Adducts and flexes hip joint
Assists with medial rotation of hip joint

4

5

Sartorius insertion

Superior part of medial surface of tibia

6

Sartorius innervation

Femoral nerve (L2, L3)

7

Sartorius action

Flexes, abducts and laterally rotates hip joint, flexes knee joint

8

Psoas major origin

Sides of t12-l4 vertebrae and discs between them, transverse processes of all lumbar vertebrae

9

Psoas major insertion

Lesser trochanter of femur

10

Psoas major innervation

Anterior rami of lumbar nerves
L1, L2, L3

11

Psoas major action

Acting conjointly in flexing hip joint and in stabilizing the joint, psoas major is also a postural muscles that helps control deviation if the trunk and is active during standing

12

Iliacus origin

Iliac crest, iliac fossa, ala of sacrum and anterior sacroiliac ligaments

13

Iliacus insertion

Tendon of psoas major, lesser trochanter and femur distal to it

14

Iliacus innervation

Femoral nerve
L2, L3

15

Iliacus action

Acts with psoas major to flex and stabilize hip joint

16

Rectus femoris origin

Anterior inferior iliac spine and ilium superior to acetabulum

17

Rectus femoris insertion

Via common tendinous (quadriceps tendon) and independent attachments to base of patella, indirectly via patellar ligament to tibial tuberosity,vast us medial is and lateral is also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula)

18

Rectus femoris innervation

Femoral nerve
L2, l3, l4

19

Rectus femoris action

Extends knee joint
Also stabilizes hip joint and helps ilio psoas flex hip joint

20

Vastus lateralis origin

21

Vastus lateralis insertion

Via common tendinous (quadriceps tendon) and independent attachments to base of patella, indirectly via patellar ligament to tibial tuberosity,vast us medial is and lateral is also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula)

22

Vastus lateralis innervation

Femoral nerve
L2, l3, l4

23

Vastus lateralis action

Extends knee joint

24

Vastus medialis origin

Intertrochanteric line and medial lip of linea aspera

25

Vastus medialis insertion

Via common tendinous (quadriceps tendon) and independent attachments to base of patella, indirectly via patellar ligament to tibial tuberosity,vast us medial is and lateral is also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula)

26

Vastus medialis innervation

Femoral nerve

28

Vastus intermedius origin

Anterior and lateral surfaces of shaft of femur

29

Vastus intermedius insertion

Via common tendinous (quadriceps tendon) and independent attachments to base of patella, indirectly via patellar ligament to tibial tuberosity,vast us medial is and lateral is also attach to tibia and patella via aponeuroses (medial and lateral patellar retinacula)
