Q1. What is the main anatomical role of perforating veins in the lower limb?
- Connect the femoral artery with the femoral vein
- Connect superficial veins with deep veins
- Connect only neighboring deep veins
- Connect arteries directly with lymphatics
Q2. Why are these vessels called perforating veins?
- They perforate arterial walls
- They enter the knee joint cavity
- They pass through the femur
- They pass through the deep fascia
Q3. What is the usual direction of flow through a competent lower limb perforating vein?
- From superficial veins toward deep veins
- From deep veins toward superficial veins
- From lymphatics toward deep veins
- From arteries toward superficial veins
Q4. Which structures help prevent reverse flow through perforating veins?
- Venous valves
- Arterial sphincters
- Lymph nodes
- Tendons
Q5. Which two venous systems are connected by true perforating veins?
- Portal and pulmonary venous systems
- Coronary and cerebral venous systems
- Superficial and deep venous systems
- Upper and lower limb venous systems
Q6. What can occur when valves in perforating veins become incompetent?
- Arterial blood directly enters the vein
- Deep-to-superficial reflux can occur
- The vein becomes a lymphatic vessel
- All lower limb venous flow stops
Q7. Which anatomical layer must a true perforating vein cross?
- Deep fascia
- Articular cartilage
- Bone marrow
- Epidermis only
Q8. Which part of the lower limb contains several clinically important perforating veins?
- Anterior abdominal wall only
- Medial leg
- Palm of the hand
- Scalp
Q9. Which physiological mechanism works with competent perforating veins to support lower limb venous return?
- Plantar fascia alone
- Calf muscle pump
- Rotator cuff
- Patellar tendon reflex
Q10. Which description best defines a lower limb perforating vein?
- An artery carrying blood to the calf
- A vein connecting two superficial veins without crossing fascia
- A vein crossing deep fascia to connect superficial and deep veins
- A lymphatic vessel draining the thigh
