Study Notes

Lymphatic System and Blood Terms

  • Lymphadenopathy: Indicates disease affecting lymph glands, often signaling infection or malignancy.
  • Lymphangiography: Imaging technique that visualizes lymphatic channels and nodes using contrast agents.
  • Lymphangioma: Tumor originating from lymphatic vessels.
  • Lymphoma: Malignancy of lymphocytes commonly affecting lymph nodes and other lymphatic tissues.
  • Lymphoscintigraphy: Utilizes a radioactive tracer to study lymph flow, identify blockages, and locate sentinel nodes.
  • Lymph Node: Acts as a reservoir for cellular debris, actively phagocytizing bacteria and harmful materials.
  • Microcyte: Refers to an abnormally small red blood cell, indicating potential anemia.
  • Neutrophil: The most abundant type of white blood cell (leukocyte), essential for immune defense.
  • Hematology: The field dedicated to studying blood cells, clotting mechanisms, bone marrow, and lymph nodes.
  • Leukocytosis: Characterized by an abnormal increase in white blood cells, often due to infection or inflammation.
  • Hemoglobin: The essential blood protein responsible for oxygen transport.
  • Platelets: The smallest formed elements in blood, crucial for coagulation.

Immune System Terminology

  • Phagocyte: A cell that engulfs and consumes foreign substances, vital for immune response.
  • Antigen: A substance that triggers the formation of antibodies, a key player in immune reactions.
  • B cells, T cells, Natural Killer Cells: Three main types of lymphocytes involved in adaptive and innate immunity.
  • Basophil: A type of granulocyte that initiates inflammatory responses.

Clinical Terms and Conditions

  • Thrombolytic: Refers to drugs that dissolve blood clots, often used in treating strokes and heart attacks.
  • Hemophilia: A hereditary disorder affecting blood clotting mechanisms, leading to excessive bleeding.
  • Hemarthrosis: Condition where blood accumulates in joints, potentially causing pain and inflammation.
  • Allergy: An abnormal immune response acquired over time, often triggered by environmental factors.

Additional Definitions

  • Serology: The study of serum, useful in diagnosing diseases through antibody detection.
  • Morphology: The study of forms and structures, particularly in cells and tissues.
  • Thymopathy: Disease affecting the thymus gland, important for T-cell development.
  • Immunotherapy: Treatment modality that modifies the immune system to enhance its ability to fight diseases.
  • Mononuclear: Relating to cells with a single nucleus, important in various blood and immune functions.
  • PT (Prothrombin Time): A test measuring the time it takes for blood to clot, particularly in patients on anticoagulation therapy.

Diagnostic Tools

  • Monospot: A rapid serologic test that detects heterophile antibodies, often used to diagnose infectious mononucleosis.
  • Bone Marrow Magnetic Resonance Imaging: A highly sensitive imaging technique for detecting bone or marrow lesions and changes.
