Question 1

Where can the majority of lymph nodes be found within the body?

Answer 1

Abdomen

Question 2

Which type of lymphatic vessel tends to accompany arteries?

Answer 2

Deep vessels

Question 3

The right lymphatic duct drains which part of the body?

Answer 3

Upper right quadrant

Question 4

Which node receives lymph from all axillary lymph node groups?

Answer 4

Apical axillary

• The apical nodes are located in the apex of the axilla, close to the axillary vein and 1st part of the axillary artery. They receive lymph from efferent vessels of the central axillary lymph nodes (and therefore from all axillary lymph node groups).

Question 5

Superficial lymphatic vessels in the upper limb lie close to which other structures?

Answer 5

Superficial veins

Question 6

The majority of superficial lymphatic vessels accompanying the cephalic vein go on to enter which set of lymph nodes?

Answer 6

Apical axillary lymph nodes

Question 7

Which structure does the left jugular lymphatic trunk empty into?

Answer 7

Thoracic duct

• The left jugular lymphatic trunk empties into the thoracic duct - which drains into the venous system via the left subclavian vein.

Question 8

At what point does the right lymphatic duct enter the venous system?

Answer 8

The right venous angle

• The right lymphatic duct enters the venous system at the right venous angle, the junction between the internal jugular vein and subclavian vein

Question 9

A patient is seen in the head and neck cancer clinic with a squamous cell carcinoma of the central lower lip. Which lymph node group is most likely to be the first site of regional metastasis?

Answer 9

Submental

• The submental lymph nodes drain the central lower lip, floor of the mouth and apex of the tongue.

Question 10

The medial superficial lymphatic vessels of the leg travel with which vein?

Answer 10

Great saphenous vein

• The medial superficial lymphatic vessels arise from dorsum of the foot, pass behind the medial femoral condyle and accompany the great saphenous vein.

Question 11

The majority of popliteal nodes will drain to where?

Answer 11

Deep Inguinal Nodes

Question 12

Which group of nodes form a line directly below the inguinal ligament?

Answer 12

Superficial inguinal nodes

Question 13

What is responsible for the lymphatic drainage of the upper right quadrant of the body?

Answer 13

Right lymphatic duct

Question 14

What is responsible for the lymphatic drainage of the rest of the body (except upper right)?

Answer 14

Thoracic duct
