One of the mysteries of the English language finally explained.
Glial cells derived from mesoderm that function as macrophages (scavengers) in the central nervous system and form part of the reticuloendothelial system.
- ‘Scavenger cells called microglia can be found in the center of plaques, and astrocytes, a type of cell that usually helps protect neurons, are found around the outside of the spherical plaques.’
- ‘The neurohypophysis was replaced by fibrotic tissue containing perivascular macrophages and activated microglia, and in the cerebellum, there were large areas of myelin pallor.’
- ‘Three cell types are found: astrocytes with their two varieties, protoplasmic and fibrous; oligodendroglia; and microglia.’
- ‘Nerve cells near plaques often look swollen and deformed, and are surrounded by inflammatory cells called microglia, which are part of the brain's immune system.’
- ‘Optic pathway gliomas in humans are typically surrounded by blood vessels and microglia, which are immune system cells in the brain.’
