Agranulocyte - Wikipedia
In immunology, agranulocytes (also known as nongranulocytes or mononuclear leukocytes) are one of the two types of leukocytes (white blood cells), the other type being granulocytes. Agranular cells are noted by the absence of granules in their cytoplasm, which distinguishes them from granulocytes.
Monocyte - Wikipedia
Monocytes are amoeboid in appearance, and have nongranulated cytoplasm. [1] Thus they are classified as agranulocytes, although they might occasionally display some azurophil granules and/or vacuoles. With a diameter of 15–22 μm, monocytes …
White Blood Cells—Granulocytes and Agranulocytes - ThoughtCo
2019年10月9日 · Monocytes: These cells are the greatest in size of the white blood cells. They have a large, single nucleus that comes in a variety of shapes but is most often kidney-shaped. Monocytes migrate from blood to tissue and develop into either macrophages and dendritic cells. Macrophages are large cells present in nearly all tissues. They actively ...

2022年11月14日 · Agranulocytes consist of lymphocytes and monocytes, and while they lack specific granules, they do contain azurophilic granules. Monocytes are precursor cells for the mononuclear phagocytic system, which includes cells such as macrophages, osteoclasts, and microglial cells in connective tissue and organs.
White Blood Cells - Granulocytes - Agranulocytes - TeachMePhysiology
2023年9月26日 · Neutrophils, eosinophils, and basophils are granulocytes since they have cytoplasmic granules which can digest microorganisms. Lymphocytes and monocytes are agranulocytes since they lack granules in their cytoplasm. This article will give a basic overview of the five main types of white blood cells.
Histology, Monocytes - StatPearls - NCBI Bookshelf
2023年4月24日 · Monocytes are white blood cells that derive from the bone marrow. A monocyte is part of the innate immune response and functions to regulate cellular homeostasis, especially in the setting of infection and inflammation.[1]
Monocyte | Complete Anatomy - Elsevier
A monocyte is a mononuclear phagocytic leukocyte, 13 to 25 μm in diameter, with an ovoid or kidney-shaped nucleus, containing lacy, linear chromatin and abundant gray-blue cytoplasm filled with fine reddish and azurophilic granules.
Blood: The Histology Guide - University of Leeds
Monocytes circulate in the blood for 1-3 days, and then migrate into body tissues, where they transform into macrophages. They will phagocytose dead cells and bacteria. Some monocytes can also transform into osteoclasts. Monocytes are important in the inflammatory response.
Agranulocyte - an overview | ScienceDirect Topics
Monocytes, previously known as agranulocytes, are the largest sized cells in MPS containing typical horseshoe-shaped nucleus in their cytoplasm. Monocytes are traditionally known as the 2nd line of defense cells after neutrophils in an innate immune system.
Agranulocytes - SpringerLink
2024年6月5日 · Agranulocytes consist of monocytes and lymphocytes. Monocytes leave the bloodstream to mature into macrophages and ingest bacteria, dead cells, cell fragments, and other tissue debris. Lymphocytes can be classified into two groups – B and T lymphocytes and natural killer (NK) cells.
