A type of immune cell that has granules (small particles) with enzymes that are released during infections, allergic reactions, and asthma. Neutrophils, eosinophils, and basophils are granular leukocytes. A granular leukocyte is a type of white blood cell.

Granulocytes are cells in the innate immune system characterized by the presence of specific granules in their cytoplasm. They are also called polymorphonuclear leukocytes (PMN, PML, or PMNL) because of the varying shape of the nucleus, which is usually lobed into three segments.

Neutrophils, eosinophils, and basophils are polymorphonuclear leukocytes. A polymorphonuclear leukocyte is a type of white blood cell. Also called granular leukocyte, granulocyte, and PMN.

The multilobed nucleus of the neutrophil can assume a variety of shapes and is hence considered polymorphic, which means many shaped. Being the most abundant of the polymorphs, neutrophils are often referred to as polymorphonuclear leukocytes (PMN) or simply polymorphs (1).

Neutrophils, eosinophils, and basophils are PMNs. A PMN is a type of white blood cell. Also called granular leukocyte, granulocyte, and polymorphonuclear leukocyte.

Being the most abundant of the polymorphs, neutrophils are often referred to as polymorphonuclear leukocytes (PMN) or simply polymorphs (1). Neutrophils are highly motile cells and play an important role in infections, inflammatory conditions and autoimmune reactions.

Neutrophil granules house critical enzymes for bacterial and fungal killing, and are mobilized to the phagosome immediately after ingestion of an invader (Figure 78-1). This intracellular trafficking requires molecular motors, which move granules around inside the cell.

Polymorphonuclear Leukocytes White Blood Cells. Polymorphonuclear leukocytes, or PMNs, are a special family of white blood cells. The family includes immune cells known as neutrophils, eosinophils, and basophils. Neutrophils, basophils, and eosinophils are all PMNs that can be found circulating in the bloodstream.

nongranular l’s leukocytes without specific granules in the cytoplasm, including lymphocytes and monocytes. Called also agranular leukocytes. polymorphonuclear leukocyte any fully developed, segmented granular leukocyte whose nuclei contain multiple lobes joined by filamentous connections, especially a neutrophil.

A normal Gram stain of sputum contains polymorphonuclear leukocytes, alveolar macrophages, and a few squamous epithelial cells. The quality of sputum samples is determined by the minimum number of squamous epithelial cells and polymorphonuclear leukocytes per low power field. Find out all about it here.

Called also agranular leukocytes. polymorphonuclear leukocyte any fully developed, segmented granular leukocyte whose nuclei contain multiple lobes joined by filamentous connections, especially a neutrophil.
