Definition
  1. Noun:
    • A type of white blood cell: A lymph cell is an agranulocytic leukocyte. This means it is a white blood cell that lacks visible granules in its cytoplasm when viewed under a microscope.
    • Normal proportion and function: It normally constitutes about one-quarter (25%) of the total white blood cell count in a healthy individual. Its primary role is in the body's immune response.
    • Response to infection: The number of lymph cells increases in the presence of an infection as part of the body's defense mechanism.
Usage Examples
  • Noun:
    • The laboratory test showed an elevated count of lymph cells, indicating a possible viral infection.
    • Lymph cells are crucial for the adaptive immune system, producing antibodies to fight pathogens.
Advanced Usage
  • In medical diagnostics: The term is used to describe a specific finding in a complete blood count (CBC) test.
    • A differential white blood cell count measures the percentage of lymph cells.
  • In immunological contexts: Often discussed in relation to specific types like T cells and B cells, which are categories of lymphocytes (a synonym for lymph cell).
    • The research focused on how specific lymph cells develop memory after an infection.
Variants and Related Words
  • Lymphocyte (n): The more common and precise scientific synonym for "lymph cell."
    • T lymphocytes and B lymphocytes are the two main classes.
  • Lymphocytic (adj): Relating to or involving lymphocytes.
    • The patient was diagnosed with a lymphocytic disorder.
Synonyms
  • Lymphocyte: The direct and most frequently used synonym in medical and scientific English.
  • Agranulocytic leukocyte: A more technical, descriptive synonym highlighting its classification among white blood cells.
Related Phrases
  • Lymph cell count: A phrase referring to the measurement of these cells in a blood sample.
    • The doctor ordered a test to check the lymph cell count.
  • Lymph cell production: Refers to the generation of these cells, primarily in the bone marrow and lymphoid tissues.
    • Chemotherapy can sometimes suppress lymph cell production.
Notes on Meaning
  • The term "lymph cell" is functionally equivalent to "lymphocyte." "Lymphocyte" is the standard term in modern medical and biological texts, while "lymph cell" is a more descriptive term that clearly indicates its identity as a cell and its association with the lymphatic system.
