Which one of the following lymphoid organs does not contain lymphoid follicles or germinal centers? (a) lymph nodes, (b) spleen, (c) thymus, (d) aggregated lymphoid nodules, (e) tonsils.
It sometimes is difficult to distinguish the different lymphoid organs from one another in histological sections. How would you tell the thymus from a lymph node? (a) Only the thymus has a cortex and medulla; (b) lymphocytes are far less densely packed in the thymus than in the lymph node; (c) the thymus contains no blood vessels; (d) only the thymus has distinct lobules and thymic corpuscles.
Which of the following lymphoid organs have a cortex and a medulla? (More than one choice is correct.) (a) lymph nodes, (b) spleen, (c) thymus, (d) aggregated lymphoid nodules, (e) tonsils.
