Why are neutrophils called polymorphonuclear leukocytes?
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).
Are PMNs neutrophils?
Neutrophils, eosinophils, and basophils are PMNs. A PMN is a type of white blood cell. Also called granular leukocyte, granulocyte, and polymorphonuclear leukocyte.
Is lymphocyte a granulocyte?
Granulocytes include neutrophils, basophils, eosinophils, and mast cells. Mononuclear leukocytes include lymphocytes, monocytes, macrophages, and dendritic cells. This group is involved in both innate and adaptive immune system function.

High lymphocyte blood levels indicate your body is dealing with an infection or other inflammatory condition.
What is the shape of WBC?
| WBC | Shape (nucleus) |
|---|---|
| Neutrophils | Multinucleated |
| Eosinophils | Bi-lobed |
| Monocytes | Kidney shaped |
| Thrombocytes | Eccentric |
What is Granulocytopenia?
Listen to pronunciation. (GRAN-yoo-loh-SY-toh-PEE-nee-uh) A condition in which there is a lower-than-normal number of granulocytes (a type of white blood cell).
What lymphocytes mean?
Lymphocytes are white blood cells and one of the body’s main types of immune cells. They are made in the bone marrow and found in the blood and lymph tissue. The immune system is a complex network of cells known as immune cells that include lymphocytes.
What do you mean by monocytes?
Monocytes are a type of white blood cell. They are produced in the bone marrow and then enter the bloodstream. They fight certain infections and help other white blood cells remove dead or damaged cells and fight cancer cells.
