Granulocyte
From Freepedia
Granulocytes are a category of white blood cells, characterised by the fact that all types have differently staining granules in their cytoplasm on light microscopy. They are also called polymorphonuclear leukocytes (PMN or PML) because of the varying shapes of the nucleus, which is usually lobed into three segments.
There are three types of granulocytes:
The granulocytes are:
Their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neutrophil granulocyte, which has neutrally-staining cytoplasmic granules.
Other white blood cells which are not granulocytes are mainly lymphocytes and monocytes.
Granulocytopenia is an abnormally low concentration granulocytes in the blood. This condition reduces the body's resistance to many infections.
