Granulocyte(Neutrophils,Eosinophils,Basophils)
A polymorphonuclear leukocyte, also known as a neutrophil, is a type of white blood cell that plays a key role in the body's immune response by attacking bacteria and other pathogens. Neutrophils are characterized by their multilobed nuclei and are one of the first cells to migrate to the site of infection.
The leukocyte characterized by a purple multilobed nucleus (typically 3 to 5 lobes) and numerous fine granules in the cytoplasm is the neutrophil. Neutrophils are the most abundant type of white blood cells and play a crucial role in the immune response, particularly in fighting bacterial infections. Their granules contain enzymes and antimicrobial substances that help in the destruction of pathogens.
Prokaryotic cells do not have a nucleus
Some leukocytes, such as neutrophils, can have segmented nuclei that appear as multiple lobes. These segmented nuclei can give the appearance of multiple nuclei when observed under a microscope. This characteristic is known as polymorphism, and it is a normal feature of certain types of leukocytes.
Prokaryotic
A white blood cell (leukocyte) containing a segmented lobular nucleus; neutorphil, eosinophil or basophil.

PMN: polymorphonuclear leukocyte because its nucleus have many lobes
polymorphonuclear
Polys (polymorphonuclear leukocytes) and segs (segmented neutrophils) refer to different stages of neutrophil development within the immune system. Polys typically refer to mature neutrophils characterized by a segmented nucleus, while segs specifically denote the fully mature neutrophils with a multi-lobed nucleus. In clinical contexts, the terms are often used interchangeably, but they can have subtle distinctions based on the developmental stage being referenced.
"band" in this case, refers to the form of the nucleus. The nucleus of a "ripe" white cell is segmented where as in a band, the nucleus looks that way, ergo NOT segmented. Therefore, a band is a younger cell. In for instance, infections where the body needs more white cells, band white cells are seen more often.
White blood cells, or leukocytes, are classified into two main groups: granulocytes and nongranulocytes (also known as agranulocytes).The granulocytes, which include neutrophils, eosinophils, and basophils, have granules in their cell cytoplasm. Neutrophils, eosinophils, and basophils also have a multilobed nucleus. As a result they are also called polymorphonuclear leukocytes or "polys." The nuclei of neutrophils also appear to be segmented, so they may also be called segmented neutrophils or "segs."The nongranuloctye white blood cells, lymphocytesand monocytes, do not have granules and have nonlobular nuclei. They are sometimes referred to as mononuclear leukocytes.
The word polymorphonuclear means having many nuclei that are not the same form. Poly- means many, -morpho- means shape, -nucl- means nucleus and -lear means having.
Some WBCs have large nuclei. This nucleus is so big that it may make the cell look dark. These cells are called polymorphonuclear lymphocytes or granulocytes. They can be neutrophils, eosinophils or basophils.
