Neutrophils

Neutrophils are granulocytes, along with basophils and eosinophils.  They can be easily differentiated from the other two granulocytes by their characteristic multilobed nucleusThe control center of the cell that contains DNA and directs cellular activities..

Nucleus

Neutrophils have a distinct feature. They are differentiated from the other granulocytes by a multilobed nucleus with at least 2 lobes. Sometimes, they can have as many as 5 lobes connected by thin strands.  Because of these nucleiClusters of neurons in the CNS responsible for processing information., neutrophils are sometimes called “polymorphonuclear leukocytes” or “polys.”

Cytoplasm

As a granulocyte, neutrophils have granules in their cytoplasmThe gel-like substance within a cell that contains organelles and cytosol..  These granules are usually smaller than those found in eosinophils and basophils.  Unlike the other granulocytes, the granules are not as densely packed. Sometimes, the space between them appears pink. This is due to the staining properties of proteinsLarge molecules made of amino acids with various functions in the body. in the cytoplasm.

Function

Neutrophils are one of the two leukocytes that are microphages (the other being eosinophils)  These microphages circulate in blood.  When tissues are injured, various chemicals are released to attract leukocytes to the area.  Neutrophils are able to recognize these substances. They exit blood circulation and enter tissues. There, they begin triage with the variety of substances in the cytoplasm.

Confused With

Neutrophils can be easily confused with basophils.  The granules of basophils are larger and the nucleus of a basophil can barely be seen.  They can also be confused with eosinophils, but the characteristic red color of the eosinophil granules tells them apart.
