Neutrophils and Eosinophils

Neutrophils

1. 10 to 12 micrometer in diameter.
2. Named for their lack of charecteristic cytoplasmic staining.
3. Also called polymorphonuclear neutrophils / polymorhs.
4.  Mature neutrophils possess two to four lobes of nuclear material joined by thinner nuclear strands.
5. In women, the Barr body(the condensed, single, inactive X chromosome) forms a drumstick shaped appendage on one of the nuclear lobes. 

Eosinophils

1. About the same size as neutrophils.
2.  Nuclei- typically bilobed.
3. Named for the large, eosinophilic, refractile granules in their cytoplasm.
