  • (^) a. Effector cells
  • (^) b. Memory cells
  • (^) c. Natural killer cells
  • (^) d. Antigen-presenting cells
  • (^) e. B lymphocytes
  • (^) Correct Answer: d. Antigen-presenting cells Question 2: Which of the following cell types is required for all humoral immune responses?
  • (^) a. Natural killer cells
  • (^) b. Dendritic cells
  • (^) c. Cytolytic T lymphocytes
  • (^) d. B lymphocytes
  • (^) e. Helper T lymphocytes
  • (^) Correct Answer: d. B lymphocytes Question 3: A previously healthy 8-year-old boy is infected with an upper respiratory tract virus for the first time. During the first few hours of infection, which one of the following events occurs?
  • (^) a. The adaptive immune system responds rapidly to the virus and keeps the viral infection under control.
  • (^) b. The innate immune system responds rapidly to the viral infection and keeps the viral infection under control.
  • (^) c. Passive immunity mediated by maternal antibodies limits the spread of infection.
  • (^) d. B and T lymphocytes recognize the virus and stimulate the innate immune response.
  • (^) e. The virus causes malignant transformation of respiratory mucosal epithelial cells, and the malignant cells are recognized by the adaptive immune system.
  • (^) Correct Answer: b. The innate immune system responds rapidly to the viral infection and keeps the viral infection under control. Question 4: Antibodies and T lymphocytes are the respective mediators of which two types of immunity?
  • (^) a. Specific and nonspecific
  • (^) b. Humoral and cell-mediated
  • (^) Correct Answer: a. Helper T lymphocytes and cytotoxic T lymphocytes Question 7: Which of the following best describes clonal expansion in adaptive immune responses?
  • (^) a. Increased number of different lymphocyte clones, each clone specific for a different antigen during the course of an infection
  • (^) b. Increased number of different lymphocyte clones, each clone specific for a different antigen during development of the immune system, before exposure to antigen
  • (^) c. Increased number of lymphocytes with identical specificities, all derived from a single lymphocyte due to nonspecific stimuli from the innate immune system
  • (^) d. Increased number of lymphocytes with identical specificities, all derived from a single lymphocyte stimulated by a single antigen
  • (^) e. Increased size of the lymphocytes of a single clone due to antigen-induced activation of the cells
  • (^) Correct Answer: d. Increased number of lymphocytes with identical specificities, all derived from a single lymphocyte stimulated by a single antigen Question 8: Which of the following is a unique property of the adaptive immune system?
  • (^) a. Highly diverse repertoire of specificities for antigens

  • (^) Correct Answer: a. Highly diverse repertoire of specificities for antigens Question 9: B cells mature in the
  • (^) a. bone marrow
  • (^) b. thymus
  • (^) c. liver
  • (^) d. brain
  • (^) e. pancreas
  • (^) Correct Answer: a. bone marrow Question 10: The principal function of the immune system is:
  • (^) a. defense against cancer
  • (^) b. repair of injured tissues
  • (^) c. defense against microbial infections
