Appearance of Mononuclear Cells

Lymphocyte or Lymph

  • Lymphocytes are a heterogeneous group of cells that have different origins, lifespans and functions, and vary markedly in size.

  • Some have a diameter of approximately 7μ, while others are as large as 18μ.

  • The variations in size are mainly due to different amounts of cytoplasm.

  • Therefore, the N:C ratio may range from 5:1 in some lymphocytes to 1:2 in others.
