In what stage of the immune response do the differentiated lymphocytes function in either a humoral or a cellular capacity?
A) The recognition stage
B) The effector stage
C) The response stage
D) The proliferation stage
Ans: C
Feedback: In the response stage, the differentiated lymphocytes function in either a humoral or a cellular capacity. In the effector stage, either the antibody of the humoral response or the cytotoxic (killer) T cell of the cellular response reaches and connects with the antigen on the surface of the foreign invader. In the recognition stage the recognition of antigens as foreign, or non-self, by the immune system is the initiating event in any immune response. During the proliferation stage the circulating lymphocytes containing the antigenic message return to the nearest lymph node.
