    Leads to four gametocytes, each contains one-half the number of chromosomes of the original cell. Meiosis occurs only in reproductive cells.
  14. Atrophy
    Is a reduction in the size of a cell or organ that may occur when cell undergoes reduced workload or disuse, insufficient blood flow, malnutrition, or reduced hormonal and nerve stimulation
  15. Hypertrophy
    Increase in cell size or organ due to increase in workload or hormonal stimulation
  16. Pathologic Hypertrophy
    Is due to disease, for example, cardiac muscle hypertrophy is due to cardiac muscle pumping against increase resistance in patient with hypertension

    Replacement of one fully differentiated cell type by another.
  21. Dysplasia
    Disordered cell growth

    genital warts
  24. Proto-Oncogene
    When mutated they cause uncontrolled cell death
  25. Helper T cell
    stimulate B-Cells to mature into plasm cells. Plasma cells synthesize and secrete immunoglobulin
  26. Suppressor T Cells
    Reduce the humoral response
  27. IGG
    It appears in all body fluids and is the major antibody against chronic bacterial and viral infection crosses the placenta
  28. IGM
    Is the first immunoglobulin produced during an immune response usually present in the vascular system
  29. IGA
    Prevents attachment of bacteria and viruses to mucous membranes and it is found in body secretions
  30. IGD
    Unclear function and it is found on the surface of C-cells and in the serum
  31. IGE
    binds to mast cells and basophilic, mediating immediate hypersensitivity reactions or allergic reactions. IGE stimulates the release of mast cell granules which contain histamine and heparin
  32. Complement System
    Activated by IGG or IGM in the classic pathway and activated by molecules on the surface of microbes (especially endotoxin) in the alternative pathway
  33. HIV is the cause of
  34. Both HIV-1 and HIV-2 cause
    AIDS, but HIV-1 is found worldwide, whereas HIV-2 is found primarily in West Africa
  35. HIV preferentially infects and kills
    Helper T Lymphocytes (CD4)
  36. HIV B infects
    mononuclear cells and appears to be passed readily during anal sex
  37. HIV E
    infects female genital tract cells and appears to be passed readily during vaginal sex
  38. Chemokine receptors, such as CXCR4 and CCR5 proteins, are required
    for the entry of HIV into CD4-positive cells
  39. Anitgens of HIV - Group-Specific Antigen
    p24 is located in the core and is not known to vary
  40. Mutations in the gene encoding CCR5 endow the individual with protection from
    infection with HIV
  41. Although small amounts of HIV virus have been found in other fluids like saliva and tears
    there is no evidence that they play a role in infection
  42. Blood Banks test for the presence of p24 antigen in an effort
    to detect blood that contains HIV
