What is the origin and insertion of vastus lateralis?

Origin - femur (lateral intertrochanteric line, margin of greater trochanter, gluteal tuberosity and lateral lip of linea aspera
Insertion - quadriceps femoris tendon

32

What is the origin and insertion of vastus medialis?

Origin - femur (medial intertrochanteric line, pectineal line, medial lip of linea aspera, medial supracondylar line)
Insertion - quadriceps femoris tendon and medial border of patellar

33

What is the innervation and 1 action of vastus lateralis?

Femoral nerve L2-L4
Extends the leg at the knee joint

34

What is the innervation and 1 action of vastus medialis?

Femoral nerve L2-L4
Extends the leg at the knee joint

35

What is the origin and insertion of vastus intermedius?

Origin - femur (upper 2/3 of anterior and lateral surfaces)
Insertion - quadriceps femoris tendon and laterla margin of patellar

36

What is the innervation and 1 action of vastus intermedius?

Femoral nerve L2-4
Extends leg at knee joint

37

In addition to the 4 quadriceps and sartorius whar 2 other muscles does the anterior compartment contain?

1) Iliopsoas muscles
2) Pectineus

38

The medial compartment contains muscles which arise from where?

The external surface of the pubis and the ischiopubic ramus

39

What 5 muscles can be found in the medial compartment of the thigh?

1) Adductor longus
2) Adductor brevis
3) Adductor magnus
4) Gracilis
5) Obturator externus

40

What is the chief function of the muscles of the medial compartment of the thigh?

Adduct the thigh at the hip joint

41

What is the origin and insertion of adductor longus?

Origin - Body of pubis
Insertion - linea aspera on medial 1/3 of shaft of femur

42

What is the innervation of adductor longus?

Anterior division of obturator nerve L2-4

43

What is the origin and insertion of adductor brevis?

Origin - body of pubis and inferior pubic ramus
Insertion - post proximal femur and upper 1/3 of linea aspera

44

What is the innervation of adductor brevis?

Obturator nerve L2-3

45

What is the origin of the adductor part of adductor magnus?

Origin - ischiopubic ramus
Insertion - Posterior proximal femur, linea aspera and medial supracondylar line

46

What is the origin and insertion of the hamstring part of adductor magnus?

Origin - ischial tuberosity
Insertion - Adductor tubercle and supracondylar line

47

What are the 2 different innervations of the adductor part and hamstring part of adductor magnus?

Adductor part = obturator nerve L2-4
Hamstring part = tibial division of sciatic nerve L2-4

48

What is the origin and insertion of gracilis?

Origin - body of pubis, inferior pubic ramus and ramus of the ischium

49

What is the innervation of gracilis?

Obturator nerve L2-4

50

What is the origin and insertion of obturator externus?

Origin - external surface of obturator membrane and adjacent bone
Insertion - trochanteric fossa

51

What is the innervation of obturator externus?

Obturator nerve L3,L4
