Q1. Which two muscles combine to form the iliopsoas tendon near the lesser trochanter?
- Gluteus medius and minimus
- Adductor longus and gracilis
- Semitendinosus and semimembranosus
- Psoas major and iliacus
Q2. Where is the lesser trochanter best seen on the femur?
- From the posterior aspect
- Only from inside the acetabulum
- From the anterior knee
- Only from the distal articular surface
Q3. Which ridge descends inferiorly from the lesser trochanter toward the linea aspera?
- Soleal line
- Intercondylar line
- Gluteal tuberosity
- Pectineal line
Q4. Which muscle attaches to the pectineal line just inferior to the lesser trochanter?
- Pectineus
- Popliteus
- Fibularis longus
- Rectus femoris
Q5. What is the relationship of the lesser trochanter to the intertrochanteric crest?
- It lies at the inferomedial end of the crest
- It lies on the distal end of the femur
- It is completely separate from the crest
- It forms the lateral end of the patellar surface
Q6. Why does the lesser trochanter provide effective leverage for iliopsoas?
- Its projection helps iliopsoas generate a hip flexion moment
- It converts iliopsoas into a knee extensor
- It prevents any movement of the femur
- It places iliopsoas inside the knee capsule
Q7. Which action can iliopsoas also contribute to in addition to hip flexion?
- Toe abduction
- External rotation of the hip
- Knee flexion only
- Ankle inversion
Q8. What type of ossification center is associated with the lesser trochanter during development?
- No ossification center
- A secondary ossification center
- A carpal ossification center
- The primary shaft ossification center
Q9. Why is the lesser trochanter useful on radiographs of the proximal femur?
- Its apparent prominence helps assess femoral rotation
- It identifies the patellar surface
- It determines ankle alignment
- It directly measures tibial length
Q10. What happens to the apparent prominence of the lesser trochanter on an anteroposterior radiograph when the femur is externally rotated?
- It moves into the knee joint
- It becomes more prominent
- It becomes the greater trochanter
- It disappears completely
