Answer 15

A B

Question 16

Compare the landmarks used to identify superficial vs. deep inguinal nodes.

Answer 16

Superficial nodes are identified by the great saphenous vein and their T-shaped pattern in the superficial fascia. Deep nodes are located medial to the femoral vein deep to the fascia lata with the femoral canal serving as a key landmark for Cloquet’s node.

Answer 18

3–5

Question 19

Which statements regarding the lateral superficial drainage are correct? Options: A. It follows the small saphenous vein B. It drains the lateral foot C. It bypasses the popliteal nodes D. It eventually reaches the deep inguinal nodes

Answer 19

A B D

Question 20

What is the clinical significance of the inguinal lymph nodes regarding the spread of infection or cancer?

Answer 20

Because they drain the skin of the entire lower limb as well as deep structures like muscles and joints these nodes are primary sites for lymphadenopathy in response to lower limb infections or metastasis from lower limb malignancies.

Question 21

Which trunk receives lymph from the para-aortic lumbar nodes? Options: A. Intestinal trunk B. Lumbar trunks C. Subclavian trunk D. Bronchomediastinal trunk

Answer 21

B

Question 22

Lymph from the anteromedial leg follows the ______ saphenous vein.

Answer 22

Great

Question 23

Choose the nodes that lie deep to the fascia lata. Options: A. Cloquet’s node B. Horizontal superficial group C. Vertical superficial group D. Deep inguinal nodes

Answer 23

A D

Question 24

Explain the relationship between the great saphenous vein and the superficial inguinal nodes.

Answer 24

The great saphenous vein acts as a primary pathway for medial superficial lymph. The vertical group of superficial inguinal nodes is specifically positioned along the terminal part of this vein before it pierces the fascia.

Question 25

The lateral foot drains to which nodes first? Options: A. Superficial inguinal B. External iliac C. Popliteal D. Para-aortic

Answer 25

C

Question 26

The ______ group of superficial inguinal nodes is located parallel to the inguinal ligament.

Answer 26

Horizontal

Question 27

Which of the following are part of the deep drainage pathway? Options: A. Deep inguinal nodes B. External iliac nodes C. Great saphenous vein D. Para-aortic nodes

Answer 27

A B D

Question 28

How does the pattern of superficial inguinal nodes differ between the horizontal and vertical groups.

Answer 28

The horizontal group is arranged parallel to the inguinal ligament in the upper thigh. The vertical group is arranged in a line following the femoral vein and the terminal great saphenous vein inferiorly.

Question 29

Which structure provides a minor route for deep lower limb drainage? Options: A. Great saphenous vein B. Small saphenous vein C. Popliteal nodes D. Superficial inguinal nodes

Answer 29

C

Question 30

The terminal destination for all lower limb lymph before entering the Cisterna chyli is the ______ nodes.

Answer 30

Para-aortic or lumbar

Question 31

Identify the areas drained specifically by the lateral superficial pathway. Options: A. Medial thigh B. Lateral foot C. Posterolateral leg D. Anteromedial leg

Answer 31

B C

Question 32

Trace the flow of lymph from a deep joint in the ankle to the venous system.

Answer 32

Lymph from the deep joint follows deep veins to the popliteal nodes then deep inguinal nodes then external iliac nodes and para-aortic nodes. It then enters the lumbar trunks Cisterna chyli and finally the thoracic duct to the left venous angle.

Question 33

What is the relation of deep inguinal nodes to the femoral vein? Options: A. Superficial and Lateral B. Deep and Medial C. Deep and Lateral D. Superficial and Medial

Answer 33

B

Question 34

The horizontal group of superficial nodes is parallel to the ______ ligament.

Answer 34

Inguinal

Question 35

Which veins are associated with the drainage of the skin of the lower limb? Options: A. Great saphenous vein B. Small saphenous vein C. Femoral vein D. Popliteal vein

Answer 35

A B

Question 36

Describe the location and significance of the saphenous hiatus in lymphatic drainage.

Answer 36

The saphenous hiatus is an opening in the fascia lata where the great saphenous vein joins the femoral vein. Many superficial lymphatic vessels and the vertical group of nodes are located around this area to facilitate drainage into the deeper system.

Question 37

Lymph from the medial thigh drains directly into which group? Options: A. Popliteal nodes B. Deep inguinal nodes C. Superficial inguinal nodes vertical group D. Parasternal nodes

Answer 37

C

Question 38

Cloquet's node is at the ______ end of the deep inguinal chain.

Answer 38

Proximal

Question 39

Which nodes are involved in draining the lateral side of the foot? Options: A. Popliteal nodes B. Superficial inguinal nodes C. Deep inguinal nodes D. External iliac nodes

Answer 39

A C D

Question 40

Summarize the difference between superficial and deep lymphatic drainage routes of the lower limb.

Answer 40

Superficial drainage follows the saphenous veins medial to superficial inguinal nodes lateral to popliteal then deep nodes. Deep drainage accompanies deep veins moving through popliteal deep inguinal and iliac nodes toward the lumbar trunks.
