Astrocytes are a type of glial cell that performs a wide range of functions in the nervous system. They provide structural support for neurons and help to maintain the proper chemical environment for neural activity. WebPenfield (1924) reinforced the view that the formation of myelin is likely the main role of oligodendrocytes. However, myelination was not considered their only function. Within the gray matter, a fraction of oligodendrocytes were termed “perineuronal” satellite cells, which did not form myelin, but were in close contact with the cell body of neurons, suggesting … hollard trucking claims
