granules

They all contain nuclei, and most of them contain granules which vary in size and staining properties.

Nuclei, basophilic granules, and all blood parasites are blue; erythrocytes are red or pink; eosinophilic granules, bright red.

A few fine neutrophilic granules are sometimes present in their cytoplasm.

Myelocytes are named according to the character of their granules—neutrophilic, eosinophilic, and basophilic myelocytes.

These granules are identical with the corresponding granules in the leukocytes just described.
