Test 12

Question 0

Rectus femoris

Answer 0

O: anterior inferior iliac spine
I: patella via quadriceps tendon and then tibial tuberosity via patellar ligament
A: all four heads extend leg at knee joint; rectus femoris muscle acting alone also flexes thigh at hip joint

Question 1

Quadriceps

Made up of four muscles

Answer 1

Rectus femoris
Vastus lateralis
Vastus medialis
Vastus intermedius

Question 2

Vastus lateralis

Answer 2

O: greater trochanter and linea aspera of femur
I: patella via quadriceps tendon and then tibial tuberosity via patellar ligament
A: all four heads extend leg at knee joint

Question 3

Vastus medialis

Answer 3

O: linea aspera
I: patella via quadriceps tendon and then tibial tuberosity via patellar ligament
A: extend leg at knee joint

Question 4

Vastus intermedius

Answer 4

O: anterior and lateral surface of body of femur
I: patella via quadriceps tendon and then tibial tuberosity via patellar ligament
A: extends leg at knee joint

Question 5

Sartorius

Answer 5

O: anterior superior iliac spine
I: medial surface of body of tibia
A: weakly flexes leg at knee joint; weakly flexes, abducts and laterally rotates thigh at hip joint

Question 6

Hamstrings

Answer 6

Biceps femoris
Semitendinous
Semimembranosus

Question 7

Biceps femoris

Answer 7

O: long head arises from ischial tuberosity, short head arises from linea aspera of femur
I: head of fibula and lateral condyle of tibia
A: flexes leg at knee joint and extends thigh at hip joint

Question 8

Semitendinusus

Answer 8

O: ischial tuberosity
I; proximal part of medial surface of shaft of tibia
A: flexes leg at knee joint and extends thigh at hip joint

Question 9

Semimembranosus

Answer 9

O: ischial tuberosity
I: medial condyle of tibia
A: flexes leg at knee joint and extends thigh at hip joint
