Question
TRUE OR FALSE
______________ 1. T cells give rise to plasma cells.
______________ 2. T cells mature in the bone marrow.
______________ 3. The constant regions of the immunoglobulin chains are the antigen
binding regions.
______________ 4. The constant regions of the antibody structure determine
immunoglobulin class.
______________ 5. Accessory cells that act as antigen presenters of foreign bacteria, thus
helping to activate the lymphocytes are neutrophils.
______________ 6. The protein molecules that protect tissue cells from viral takeover are
collectively called interferons.
______________ 7. Lymphokines are produced by macrophages.
______________ 8. The T cell responsible for tempering and shutting down the immune
response when the pathogen has been routed is the helper T cell.
______________ 9. The failure of the immune system to tolerate self results in
immunodeficiencies.
______________ 10.The four cardinal signs of inflammation are heat, redness, pain, and
immobility.
______________ 11.Memory T cells produce antibodies when a previously recognized
antigen appears in your body a second time.
______________ 12.The initial response to an antigen is called the primary response.
______________ 13.The initial response to an antigen is always faster and more vigorous
than the secondary response.
______________ 14.Cytotoxic T cells may destroy a “foreign” cell by releasing a
destructive protein called perforin, by secreting a poisonous
lymphotoxin, or by activating apoptosis within the target cell.
______________ 15. T Cells are monocytes.
