- Medullary cord
- Subcapsular sinus
- Germinal center
- High endothelial venule
Q2. What are trabeculae of a lymph node?
- Connective tissue extensions from the capsule
- Clusters of erythrocytes
- Bundles of skeletal muscle
- Venous valves at the hilum
Q3. What distinguishes a secondary lymphoid follicle from a primary follicle?
- Presence of a central artery

- Absence of lymphocytes
- Presence of a germinal center
Q4. What is the main significance of a germinal center in a lymph node?
- T cell maturation from stem cells
- Activated B cell proliferation and differentiation
- Erythrocyte destruction
- Urine filtration
Q5. Which specialized vessels allow many circulating lymphocytes to enter a lymph node from blood?
- Afferent arterioles of the kidney
- High endothelial venules
- Pulmonary venules
- Splenic sinusoids
Q6. What do medullary cords contain?

- Afferent vessels, subcapsular sinus, cortical sinuses, medullary sinuses, efferent vessels
- Efferent vessels, cortex, afferent vessels, hilum
- Medullary cord, artery, subcapsular sinus, portal vein

Q8. What is located at the hilum of a lymph node?
- Only lymphoid follicles
- Only afferent lymphatic vessels
- Only adipose tissue
- Efferent lymphatics, blood vessels, and nerves
Q9. Why are lymph nodes commonly arranged in regional groups?
- They prevent lymphatic vessels from communicating
- They drain and monitor defined anatomical territories
- They replace peripheral nerves
- They generate arterial blood for each region
Q10. Which structural feature slows lymph movement and increases contact with immune cells inside a node?
- The absence of macrophages
- The fibrous capsule alone
- A single straight central vein
