Q1. Which proximal femoral landmark contributes to the origin of vastus lateralis?
- Femoral head
- Lesser trochanter alone
- Greater trochanter
- Medial condyle
Q2. Which ridge of the femur provides a major posterior origin for vastus lateralis?
- Medial lip of the linea aspera
- Intercondylar line
- Lateral lip of the linea aspera
- Pectineal line only
Q3. Which femoral landmark proximal to the linea aspera also contributes to vastus lateralis origin?
- Adductor tubercle
- Fovea capitis
- Medial epicondyle
- Gluteal tuberosity
Q4. Which spinal nerve roots are classically associated with femoral nerve supply to vastus lateralis?
- L1 and S1 only
- L4, L5, and S1
- S1, S2, and S3
- L2, L3, and L4
Q5. Which vessel is particularly important in the arterial supply of the lateral quadriceps?
- Inferior gluteal artery only
- Descending branch of the lateral circumflex femoral artery
- Medial plantar artery
- Anterior tibial artery
Q6. Which fascial partition is attached to the femur beside vastus lateralis?
- Lateral intermuscular septum
- Obturator membrane
- Flexor retinaculum
- Medial intermuscular septum of the leg
Q7. Which distal fibrous structure receives expansions from vastus lateralis around the patella?
- Lateral patellar retinaculum
- Medial collateral ligament
- Transverse acetabular ligament
- Arcuate popliteal ligament
Q8. Why is vastus lateralis commonly selected as an intramuscular injection site?
- Its large accessible muscle belly
- Its position within the popliteal fossa
- Its direct continuity with the femoral artery
- Its location inside the femoral canal
Q9. How does vastus lateralis differ from rectus femoris in proximal joint anatomy?
- Vastus lateralis crosses both hip and knee
- Vastus lateralis does not cross the hip
- Neither muscle crosses the knee
- Rectus femoris crosses only the knee
Q10. What role can vastus lateralis play when the knee tends to flex under body weight?
- It plantarflexes the ankle
- It increases knee flexion as a hamstring
- It abducts the thigh as its primary action
- It helps resist knee flexion through an extension moment
