Question 11

Psoas major: Insertion

Answer 11

Lesser trochanter of femur

Question 12

Psoas major: Innervation

Answer 12

Anterior rami of lumbar nerves (L1, L2, L3)

Question 13

Question 16

Rectus femoris, Vastus lateralis, Vastus intermedius: Arterial Supply

Answer 16

Lateral circumflex femoral artery

Question 17

Vastus lateralis: Origin

Answer 17

Greater trochanter, lateral lip of linea aspera

Question 18

Vastus medialis: Origin

Answer 18

Intertrochanteric line, medial lip of linea aspera

Question 19

Vastus medialis: Arterial Supply

Answer 19

Femoral artery, deep femoral artery, and superior medial genicular branch of popliteal artery

Question 20

Vastus intermedius: Origin

Answer 20

Anterior and lateral surfaces of femur shaft

Question 21

Quadriceps: Insertion

Answer 21

Via common tendinous (quadriceps tendon), independent attachments of base of patella, indirectly via patellar ligament to tibial tuberosity, VM and VL attach to tibia and patella via aponeurosis (medial and lateral patellar retinacula)

Question 22

Quadriceps: Innervation

Answer 22

Femoral nerve (L2, L3, L4)

Question 23

Quadriceps: Action

Answer 23

Extend knee joint, RF also stabilizes hip joint and helps iliopsoas flex hip joint
