A&P2-ClassNotes P39 Immune Sys #8/Test 3
| Question | Answer |
|---|---|
| COMPLETE ANTIGENS: | are antigens that have at least two ANTIGEN DETERMINANT SITES-one for each of the antigen binding sites of an antibody molecule |
| ANTIGENIC DETERMINANT SITES are the portions of the: | antigen that are exposed and will react with an antibody |
| HAPTENS are: | PARTIAL ANTIGENS |
| PARTIAL ANTIGENS are molecules that: | are two small to initiate an immune response on thier own |
| Partial antigens can link with a CARRIER to: | create a complete antigen |
| A complete antigen is a: | combination that will activate body defenses |
| The carrier may contribute: | An antigenic determinant site |
| The antibodies produced will attack both: | the antigen and its carrier molecule (ie:poisen ivy, cosmetics, etc...) |
| Most antigens have multiple antigenic determinents and: | either antibodies or lymphocytes can attach to them |
| Self-antigens are not antigenic to us, but: | form a basis for transfusion reactions & implant rejections in others |
| MHC stands for: | MAJOR HISTOCOMPATIBILITY COMPLEX |
| MHC proteins are glycoproteins that: | are on our cell membranes & specifically mark those membranes as self |
| HLA stands for: | HUMAN LEUKOCYTE ANTIGENS |
| HLA's are part of the : | MHC system |
| Healthy cells have MHC peptides that: | are produced from the breakdown of normal cellular proteins & processes |
| Classes of MHC proteins include: | CLASS 1 MHC & CLASS 11 MHC |
| Class 1 MHC - all body cells except: | RBC's |
| Class 1 MHC is the class that: | activates cytotoxic T-cells |
| CLASS 11 MHC is located on the surface of: | mature B-cells, some T-cells and macrophages. |
| The Class 11 MHC is used to allow cells to: | recognize one another during a battle |
| The IMMUNE SYSTEM is ______ specific. | antigen |
| The Immune system is systemic, not isolated to: | initial infection site. |
| The immune sys is equipped with memory after: | initial attacks |
| There are several forms of immunity and they all: | involve defensive T-cells & B-cells. |
| T-cells cannot react to antigens in: | solution and B-Cells cannot cross a cell membrane. |
| Why do you need both T & B cells? | T cells cannot react to antigens in solution and B-cells cannot cross a cell membrane. |
| The t-cells defend against: | abnormal cells as well as antigens within cells |
| B-cells defend against pathogens: | outside the cell that are within the body fluids |
