Neutrophil

• neutrophil granulocyte
• common leukocyte in blood smears, about 60% neutrophils (50% - 70%)
• nucleus is divided into 3-5 lobes connected by thin strands of chromatin.
• lobe number increases with cell age (old cells up to 7 lobes).
• contain two types of granules stain only weakly if they are at all visible ("neutral").

Granules

• primary granules (A granules)
  • contain lysosomal enzymes and are probably primary lysosomes.
  • larger (0.4 µm) than the typical primary lysosome.
• secondary granules (B granules)
  • the specific granules of the neutrophils
  • contain enzymes with strong bactericidal actions
  • these granules stain only weakly if they are at all visible ("neutral").
