Q1. Which part of the femoral head normally lacks articular cartilage?
- Fovea capitis
- Anterior articular surface
- Superior weight-bearing surface
- Posterior articular surface
Q2. Which artery is the principal source of blood to the adult femoral head?
- Fibular artery
- Medial circumflex femoral artery
- Anterior tibial artery
- Inferior gluteal artery alone
Q3. How do the principal retinacular vessels reach the femoral head?
- They travel exclusively through the femoral shaft cavity
- They pass through the patellar ligament
- They enter only through the greater trochanter
- They ascend along the femoral neck
Q4. Which artery may contribute a vessel to the femoral head through the ligament of the head?
- Dorsalis pedis artery
- Obturator artery
- Popliteal artery
- Fibular artery
Q5. How does the femoral head relate geometrically to the acetabulum?
- The head articulates with the obturator foramen
- Two flat surfaces oppose each other
- A cylindrical head fits into a hinge
- A convex head fits within a concave socket
Q6. Why is the superior femoral head important during weight bearing?
- It anchors the quadriceps tendon
- It forms the knee extensor mechanism
- It does not contact the acetabulum
- It transmits substantial compressive load
Q7. Which structure deepens the acetabular socket around the femoral head?
- Lateral meniscus
- Acetabular labrum
- Patellar retinaculum
- Plantar aponeurosis
Q8. What is the relationship of the femoral head to the fibrous capsule of the hip joint?
- It lies within the knee capsule
- It is entirely extracapsular
- It is intracapsular
- It is subcutaneous
Q9. Why is the fovea capitis not part of the smooth weight-bearing articular surface?
- It contains the greater trochanter
- It receives the gluteus medius tendon
- It articulates with the patella
- It serves as a ligament attachment site
Q10. Which feature of the femoral head helps permit flexion, extension, abduction, adduction, and rotation?
- A hinge formed by the femoral condyles
- Its approximately spherical articular geometry
- A flat tibial articulation
- A rigid fusion with the acetabulum
