Immunology Lecture
| Question | Answer |
|---|---|
| Which of the following substances is produced by plasma cells (mature B cells)? | immunoglobulins |
| The cell markers present on the surface of all cells that indicate "self" or "non-self" are called | epitopes |
| The classification of immunoglobulin responsible for allergic reactions by stimulating Mast Cells to release histamine is | IgE |
| The primary immune system organ which produces stem cells, many of which will eventually mature into various types of lymphocytes, is(are) the | bone marrow |
| The chemical message substances released from Helper T cells which not only regulate B cell maturation and proliferation, but also differentiation of immature T cells into mature cytotoxic and regulatory T cells are | lymphokines |
| Type IV - Delayed Hypersensitivity | Contact dermatitis for latex, adhesive, topical medication, or cosmetic sensitivity |
| Type III - Immune Complex Disease | Acute inflammation and local tissue damage due to the clumping of normally circulating antigen-antibody complexes. Ex: systemic lupus erthematosus |
| Type I - Immediate/Allergic | Typical allergic reactions such as hay fever. May result in anaphylaxis |
| Type II - Cytotoxic Reactions to Self | The body's own tissue is recognized as foreign and the immune system is activated. Results in slow destruction of cellular membranes of normal tissues. Ex: blood transfusion reactions, myasthenia gravis |
| The most appropriate position to place a person in if he/she is experiencing anaphylatic shock is | supine with feet elevated |
| Passive Natural Immunity | D. Transplacental, colostrum, and/or breast milk antibody exposure from mother to fetus/baby |
| Passive Artificial Immunity | Inoculation of antibody or antitoxin |
| Active Natural Immunity | Natural contact and infection with an antigen (environmental exposure) |
| Active Artificial Immunity | Inoculation of antigen (vaccination); live or dead antigen |
| antigen | Any foreign substance in the body that does not have the characteristic cell surface markers of that individual and is capable of eliciting an immune response |
| The neuroendrocrine organ essential for regulation of the immune system is the | Pituitary |
| The immune organ where T cells differentiate from their origin of lymphoid stem cells and mature is(are) the | thymus |
| Primary organs of the immune system | bone marrow and thymus |
| secondary organs of the immune system | lymph nodes, spleen, tonsils, adenoids, appendix |
| Tissues of immune system | peyers patches |
| cells of immune system | luekocytes, lymphocytes (NK cells), other phagocytes |
| granulocytes | neutro-, eosino, baso-phils |
| the _____ filters and destroys old RBCs | spleen |
| What is the spleens immune role? | filters blood antigens |
| monocytes produce what | macrophages |
| ______ bring in Ag thru the blood to the spleen | macrophages |
| the spleens ______ destroy antigens | T cells |
| the spleen's ______ produce and antibody vs the antigen | B cells |
| mature B cells differentiate into | plasma cells |
| any substance capable of triggering an immune response is a _______ | antigen |
| epitopes- | anything on the antigen that the antibody identifies and attaches to |
| what happens if an epitope is misinterpreted where self is identified as nonself | auto immune disease |
| proteins present on the surface of all cell bodies | self markers/ MHC |
| what allows the immune system cells to recognize and communicate with one another? | MHC |
| growth and reproduction of stem cells are controlled by proteins called: | growth inducers and differentiation inducers |
| the most numerous of WBCs; die after phagocytosis and contribute to pus formation | neutrophils |
| These cells clean up after neutrophils and kill any damaged but not dead backteria or too large for neturophils | monocytes |
| weak phagocytes that participate in allergic disorders; destroy parasites | eosinophils |
| histamine is produced by what cells | basophils |
| basophils- | similar to mast cells; produce histamine; |
| NK cells are what type | lymphocytes |
