Flashcards in test 4 anterior thigh Deck (26):
1

Pectineus origin

Superior ramus of pubis

2

Pectineus insertion

Pectineal line of femur, just inferior to lesser trochanter

3

Pectineus innervation

Femoral nerve (L2, L3); may receive branch from obturator nerve

4

Pectineus action

Adducts and flexes thigh; assists with medial rotation of thigh

5

Sartorius origin

Anterior superior iliac spine and superior part of notch inferior to it

6

Sartorius insertion

Superior part of medial surface of tibia

7

Sartoriusinnervation

Femoral nerve (L2, L3

8

Sartorius action

Flexes, abducts, and laterally rotates thigh at hip joint; flexes leg at knee joint

9

Iliopsoas is made....

psoas (major) and iliacus

10

Quadriceps femoris is made.....

-rectus femoris
-vastus lateralis
-vastus medialis
-vastus intermedius

11

Rectus femorisorigin

Anterior inferior iliac spine and ilium superior to acetabulum

12

Rectus femoris insertion

Via common tendinous (quadriceps tendon) and independent attachments to base of patella; indirectly via patellar ligament to tibial tuberosity

13

Rectus femoris innervation

Femoral nerve (L2, L3, L4)

14

Rectus femorisaction

Extends leg at knee joint; rectus femoris also steadies hip joint and helps iliopsoas flex thigh

15

Vastus lateralis origin

Greater trochanter and lateral lip of linea aspera

16

Vastus lateralis insertion

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

17

Vastus lateralis innervation

Femoral nerve (L2, L3, L4)

18

Vastus lateralis action

Extends leg at knee joint

19

Vastus medialis origin

Intertrochanteric line and medial lip of linea aspera of femur

20

Vastus medialis insertion

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

21

Vastus medialis innervation

Femoral nerve (L2, L3, L4)

22

Vastus medialis action

Extends leg at knee joint

23

Vastus intermediusorigin

Anterior and lateral surfaces of shaft of femur

24

Vastus intermedius insertion

Via common tendinous (quadriceps tendon) and independent attachments to base of patella; indirectly via patellar ligament to tibial tuberosity

25

Vastus intermedius innervation

Femoral nerve (L2, L3, L4)

26

Vastus intermedius action

Extends leg at knee joint
